I have used this size coil on the Gold Racer but not Racer 2. In most ground a coil that much larger will of course add depth, but if in anything but sparse targets has a much greater chance of multiple targets under coil at same time and harder to pinpoint with. In extremely bad ground depth gains can be minimal as the coil sees way more ground, calling for reduced Gain settings to compensate. In other words, mileage can vary with oversize coils on VLF detectors. In milder ground it would add substantial depth. Substantial with large coils on a VLF usually translates into 10% to 20% more depth on coil size targets, or an inch or two. Doubling VLF coil size comes nowhere close to doubling depth on coins unfortunately. The larger the item, the better the relative depth gains.

Here is the RC40 on the Gold Racer...

After digging tin all day with the racer2 the ctx3030 is sounding better and better.

Steve, what kind of depth increase would I see with the 3030 vs. racer2?

You will not see a big depth increase per se. Just more solid, more reliable target id numbers at depth. I honestly have not used both enough comparatively to put an amount or percentage to such a thing, and it varies anyway depending on your ground. When I have more time to run the CTX and Racer 2 side by side on found targets I might have more of an opinion on that.

What makes the Minelab multi frequency units special is not raw depth, but accurate discrimination to depth. The machines tend to hold reliable id numbers until the signal gets lost. Machines like the Racer 2 have decent depth but target numbers can vary a lot at depth. In my ground for whatever reason aluminum tends to upscale so you can get a nice coin type signal at depth only to get an aluminum beaver tail off an old pull tab. Then once out of the ground the target numbers drop to where the item should be. Up scaling non-ferrous targets can be just fine if you want to dig all non-ferrous targets, but not good when you are in a nice park and want every hole to count. And putting aside all the multi frequency marketing fluff the reality is the Minelab BBS and FBS units tend to act like lower frequency units with their affinity to high conductive targets like silver coins. Yet they do just fine on low conductive also.

Anyway, I am not wanting to make it out like there is something wrong with the Racer 2 for coin detecting, it is just that they are being made out to be something just a bit more super duper than they really are. I am just trying to dial the hype back a bit.

Here is a tidbit. I hunted an area recently in a park with the CTX and 11" coil quite carefully, and pulled up a dozen coin, nothing exceptional. I then went back and hunted same area carefully with Racer 2 and 5" coil. I wanted to see if the smaller coil and quick recovery might find something hidden from the CTX with larger coil. Two targets made me dig them, one a penny, and one an aluminum beaver tail just like I described above that read as a coin until out of the hole. No real conclusion to it other than for that one little test I came away pleased with how the CTX had done. It took me twice as long to hunt that ground with the little coil only to come up with one more target. But do not read too much into it. Just one little data point is all it is.

Thanks for the quick response. I've been loving the racer2 its been working really well in all the iron rubbish around the sites I've been visiting, I pretty much keep it in two tone just hunting for those sweet, non-ferrous tones.  It's a great machine, that's built we'll and it's easy to use. It's those little flat pieces of tin that always have me digging holes they sound too good to pass up on. I spend most of my detecting time prospecting but have started looking for coins and jewelry when I can't get out to the gold fields, it's a blast and it keeps my son interested. He gets a little bored looking for nuggets when the targets are far and few in between, anyway sounds like a good enough excuse for another toy.

Hmm, the Racer 2 sounds ok, but I still had my best ever coin depth results ,in ground, with a Tesoro Tejon and stock coil like 10 years ago. Deepest was a wheatie in dry ground with my Lesche digger completely in the hole, handle and all. I only got rid of it cause it was an iron magnet and did not have VCO audio. Is it possible to add VCO to a detector that does not have it? And my old Fisher CZ6 with 3 tone audio id and meter, could hit a silver dime in black dirt at 10+ inches with the stock coil. Might need to find me one of them again ....

Unless you are a techie adding VCO is not something most of us can do. If you are looking for a single frequency detector with "more depth" all I can say is that I personally believe that particular wall got hit in the 1990s. Whenever I hear talk about a new VLF and how it gets "more depth" I frankly just ignore it. We have gotten better ability to discriminate and/or separate targets that adds up to more effective depth but that's about it.

In other words, your old Tejon goes about as deep as any single frequency VLF can be expected to detect. Lots of people still running CZ detectors also and for that matter they are still sold new as one of Fishers top of the line models.

I'm a bit of a Makro fan. I bought first run Racer, Gold Racer and Racer 2.                                        I sold the original Red Racer in anticipation to getting the Racer 2.  I have to say I was a little       disappointed with the R2.  I liked the added features but did not like what they did with the tighter iron zone.  The VID is very jumpy compared to the original Racer that would lock on to coins real hard.  I think if they would have took the original 0-40 iron range of the Red Racer and made it     0-20 instead of 0-10 it would have been perfect.  I sold the R-2 and am down to the Gold Racer (which im not selling anytime soon) and my CTX.   The CTX somehow has the ability to ID coins   accurately at depth in bad soil like no other detector I have yet to use.  I had a 12.1" certified Tom tuned CZ-5 that would call a dime a nail at 7" in my soil but my CTX can go to 10" with accurate ID. 

The Gold Racer is so unique that I don't see getting rid of it.  The Big 13" coil runs awesome on the Gold Racer and I just received the new little elliptical today.  I love the size of it and can't wait to use it.  My only complaint about the gold racer is the hallow 10x5 coil.  I wish it was solid.

Can't you cut out and attach a thin clear piece of lexan or plexiglass to the spoked Racer coil with nylon ties so it doesn't hang up on weeds?

MAKRO---

I don't see why not.... maybe the ties would be a snag point----- why not just use some rubber cement or something that can be peeled off easily---

Dilek----Are there any plans to make us a coil cover for the 15x13.5 coil???

( I admit haven't even looked to see if there is one available... because usually they are good enough to include one if they have them )

I will have to experiment with mine....

Using it at the beach last weekend I found the open spokes good for back filling my holes-- I would just pull it backwards over my sand pile and it would level it out....

(still can't figure out why my plastic bolt failed):huh:

This coil hit so hard on a nickel I just knew I had a gold ring--- approximately 8-9 inches deep in dry to damp sand... It was like BAM!!!! ---:wub:

The 15 x 13 coil comes with a fitted scuff cover. A full cover would be nice for some applications but they do collect a lot of debris.

      I have used many metal detectors over the years, and right now I have to say that the new Makro Racer 2 has perhaps the easiest to understand, best laid out, most practical display and menu system I have ever seen in a top end detector. Now, you can sure say you hunt by ear and do not need a screen and I get that, but if we are going to put a screen on a detector, then let's do it right.
      Simple detectors with few functions are easy to make screens for - there is not much you need. But even then just the basics are often wrong. Machines that feature target id numbers, what is the thing you will most look at on screen? The target id numbers! Yet these are often way too small or off to the side as if an afterthought.
      The Makro Racer 2 id numbers are huge, much larger than on the original Racer and Gold Racer, which are already good sized. The number 88 display in the diagram above is fully 1.5" x 1.5" in size in real life. Other machines have some pretty big numbers but I think this sets a record as I can't think of any machine with larger id numbers on screen though some are close.

      Makro Racer 2 LCD display and controls

      Makro Racer 2 screen layout

      Makro Racer 2 screen and control descriptions
      The number can be the ground balance number, target id, or depth reading. You get a text display just above the number confirming which it is. Below the numbers are three zone references, Fe, Gold/Non-FE, and Non-Fe, that are used to set tone breaks and audio for the three main zones or bins as they are sometimes called.
      Another basic feature lacking on a lot of machines - the meter backlight. With the Racer 2 you get off, intermittent, or full time backlighting, and it includes the translucent red control buttons. The control ranges between 0-5 and C1-C5. At 0 level, the keypad and display backlight are off. When set between 1-5, they light up only for a short period of time when a target is detected or while navigating the menu and then it goes off. At C1-C5 levels, the keypad and display will light up constantly. I do not know of anyone doing a better backlight.
      The right side of the meter is informational - ground phase (ground balance number), mineral % (ground magnetite content), coil warning notices, and a six segment battery meter.
      Across the top below the 0 - 99 reference sticker, is a series of 50 "bullets" each of which covers 2 target id numbers. Open bullets (which appear gray in the diagram but are invisible in real life - see top photo) indicate accepted target id numbers. Blacked out segments show what discrimination and notch setting you have programmed in a single quick glance. When a target is detected, the big number on the display will be mirrored by one or more of the bullets flashing dark.
      The four control buttons are simple as can be - up and down takes you through the left hand menu area. Right or left lets you set each function selected by going up and down. The menu is basically the entire feature list just laid out right there for you to see. You want to know what this machine can do, just look at the screen. Most other machines you have no clue without reading the owners manual or at least pushing buttons to see what functions appear.
      Some settings like the backlight are system wide for all modes. All other settings like Gain are independent in each mode, and can be saved independently in each mode. This means you can play neat tricks like setting up a couple modes with dramatically different settings and then flip back and forth easily between two modes for target checking.
      You even get to decide what mode is the default start up mode. The Racer 2 starts up in the last mode where the save function was performed. If you always want to start in Beach mode, just modify and save something in Beach mode. Next time you start the detector, you will be in Beach mode.
      It is simple. It makes sense. No cryptic abbreviations or acronyms. No sub menus. It is, in metal detector terms, a work of art. Whoever designed this should sign it so I can frame it and hang it on my wall.

      Hello all...as we are getting many emails and messages inquiring about the Racer, we would like to give you a little bit more info.
      The device has 2 versions - Racer and Gold Racer.
      Racer is the coin & relic device and the Gold Racer is the prospecting one as the name implies. Racer will be launched first and Gold Racer will follow a few months after that. Racer runs on 14KHz. Gold version - waiting for the final testing stage.
      We will be visiting USA next week to meet our distributors and upon our return we are planning to launch the product.
      So we are expecting to start shipments early February if all goes smooth. Should there be any changes, I will definitely inform you.
      Thank you everybody!

      I got my new coil and played sick at work to run this thing on our claim. 
      So the claim has lots of desert bed rock and very small gold on it. I have picked it over with the makro and the monster. Others have done the same with a sdc2300 and gb2. So, needless to say the pickings are slim these days. Matter of fact I have been skunked the last two times. Both of those times with the monster using the small coil. Not so this time out. I only found one small nug. It is .8 grains it was about 1.5"-2" down in a bedrock wedge. I am very happy with this coil. I really like the size and shape. I feel I could go toe to toe with a gb2 sniper coil, with this new setup.

      Tried out a new detector on Saturday:

      Due to some unavoidable delays, I finally made it out with my Makro Gold Racer on the weekend to see what it could do.

      I don't know about where you live, but winter here just didn't want to let go this year. I mean, we had one of the coldest, longest winters we've had in forever, and snow, snow, snow (we're about four feet over the average mountain snowpack at the higher elevations as I write), but Old Man Winter finally took a breather, and so I got a chance to head to the mountains to swing the coil again.

      The place I picked was one that didn't have a lot of exposed bedrock, just a small section really, with the rest of the ground covered with six to eight feet of overburden on top of the bedrock, and that's just too much overburden for the size of gold I commonly find.

      As for the weather that day, it was a true mixed bag. I mean this time of year, we can get all four seasons in one day! Saturday was no exception. It rained early in the morning, then the sun came out and it was nice and warm, then it clouded over, started to rain again, then turned to snow, then the wind blew a cold blast of air for about an hour, then the sky turned blue and the sun came out once more, the wind stopped, and the weather did its best spring imitation for the next three hours.

      I unlimbered the Gold Bug Pro first, and you can't make this stuff up, within three minutes, I'd found a three gram nugget, one my wife said looked sort of like a four-leaf clover. And, Nature indeed had made it look kind of like one. The nugget was sitting in some tough clay that held a lot of former river stones, so it seemed to me that it was likely what used to be the bottom of a crevice long ago, as the surrounding bedrock had been cut down at least a couple of feet by the former placer miners whose actions would have left the sort of deposit I've described.

      I kept working the exposed bedrock and any places I could find where bedrock had been tossed out in case some gold had ridden out with it. (I have found nuggets this way before.) I really took my time and went slow, because I wanted to be sure I'd cleaned the area before I broke out the Gold Racer so I'd have as accurate a comparison as I could. By the time I'd finished with the Fisher, I'd gathered another gram and a half of small stuff that I'd thrown in the bottle.

      My wife had wandered off, and I found her panning near the foot of channel wall, but she wasn't having much luck; however, she pointed out something to me that I'd have completely missed. To the north and east of where she'd been panning, there was a short section left of what had been a bedrock drain, and there were small sections of bedrock still exposed that the boulder clay hadn't reclaimed.

      Nevertheless, I headed back to the original bedrock I'd worked with the Gold Bug Pro, and I broke out the shiny new Makro Gold Racer. The ground balance worked flawlessly, and setting the sensitivity was a breeze. The ground was moderate to a little hot, so I didn't have to worry about adjusting the ISAT, and I was pretty familiar with the types of hot-rocks I'd likely find, so I knew most, if not all, of them by sight. 

      I started by running the coil slowly over the areas I'd hit with the Bug Pro, and after a few sweeps, I had several quiet but distinct signals. When I dug down, the signals got louder. I called by wife over, and she took the dirt with the signals and panned them out. Neither one of us could believe the tiny gold in the pan! The Gold Racer really did deliver on finding small gold. However, the first bedrock area was not where I realized how good the Gold Racer could perform.

      Remember I mentioned the bedrock drain? I headed over to it with both detectors. First, I scanned the small exposed areas exceptionally carefully with the Bug Pro, and I got a few small pieces, then I ramped up the sensitivity on the machine as far as I could, fought the background chatter, and all in all, liberated about half a gram of gold from the bedrock. 

      I swapped out the Bug Pro for the Gold Racer and covered the same areas again. Almost immediately I had a signal. I couldn't believe it, but the signal was clear, and I could see a previous dig mark where I'd nailed some small stuff with the Bug Pro, and the Racer was giving a crisp signal, quite unmistakable, right in the same dig hole! To make a long story short, three inches of bedrock later, a nice picker was in the bottle! This blew me away, as the Gold Racer had found the target while running nice and quiet, with the sensitivity not ramped up, yet the signal was very clear.

      I kept at the small sections of bedrock, and kept getting quiet, but clear, signals until I'd added another gram and a half of small gold to the vial. (Sometimes I'd get a break in the threshold too, but when I dug down, the signal either disappeared or it turned out to be a target. [Some heavy iron deposits in the bedrock did give a weak signal, but I soon learned that due to the broad nature of their signature exactly what they were.]) 

      What this weekend's outing made me realize is that if I'd have given the Gold Racer a run the end of last summer, I'd have undoubtedly recovered a lot of small gold, and I do mean a lot, that the Bug Pro just couldn't see (this test was carried out with virtually the same coil sizes on both machines, elliptical shapes and DD's as well), and knowing now what I likely left behind last summer makes me a bit sad. (Out of six grams of gold for the Saturday, a gram and a half was fine stuff from the Gold Racer, and that's a pretty good added portion of gold recovery I'd say.)
      In fairness to the Gold Bug Pro, let me say this: I've found lots and lots of gold with that great little machine, and it's super easy to learn how to use making for a quick learning curve. In addition, I don't have an unkind word to say about the Fisher as it's paid for itself many, many times over, and I will continue to use it, and I'll continue to train others how to use it as well. Moreover, let me say that the Bug Pro doesn't run at nearly as high a kHz, so it's unfair to compare apples to oranges that way, but I wanted to see what I was leaving behind, that's all.

      So, I learned my lesson well on Saturday, and I gained a whole lot of respect for the little Gold Racer for how sensitive it is to small gold, how good it punches into the ground to find it, and how quietly it goes about its job of doing so. Furthermore, The Makro is a great little gold machine I can swing all day long, and I'm looking forward to really taking it for a long, dedicated run this summer to add more gold to the poke because it sure gets the job done in style! (How I wish some fine company would produce a light-weight gold-hungry pulse machine with excellent capabilities or that Minelab would find a way to lighten the technology package of their GPZ 7000. Wouldn't that be great?)
      (I'd like to thank Steve for pointing me in the direction of the Gold Racer, and I'd like to thank Dilek at Makro for her exceptional customer service.)

      All the best,

      Lanny

      The Makro Gold Racer has been one of my most anticipated new VLF metal detectors in years. This completely new model represents something I have wanted for a very long time – a high frequency VLF metal detector that does not skimp for features, in particular as regards discrimination options.

      A little background. First, I have been testing prototypes of the Makro Gold Racer, and this review is based on those prototypes. The final version due soon has a completely new LCD display layout, audio boost, refinements to other settings, and physical refinements like a change in the handle angle, etc. That being the case this review should be considered preliminary and final specifications are subject to change, as well as details you may see in my photos regarding the physical design of the detector.

      Second, what is the intended market for the Makro Gold Racer? The machine looks deceptively like many other detectors aimed at general purpose metal detecting. I want to emphasize that first and foremost this is a gold prospecting detector. There are only a few other detectors that directly compare to the Gold Racer which is running at a very high frequency of 56 kHz. Comparable detectors would be the White’s GMT at 48 kHz, the Minelab Eureka Gold running in its 60 kHz setting, and the Fisher Gold Bug 2 at 71 kHz.

      The intent with very high frequency detectors is to sharpen the response on extremely small metal targets. High frequency detectors are in a niche all their own when it comes to finding the tiniest of gold nuggets. This sensitivity does come at a cost however, in that the detectors are also responsive to ground mineralization and hot rocks that less sensitive, lower frequency detectors might ignore completely. There is no free lunch in detecting, and I want to caution anyone thinking that the Makro Gold Racer is going to be a magical solution to all their detecting desires to be realistic about things. Inevitably when new detectors come out people fall victim to wishful thinking, and I would like to try and avoid that here.

      When it comes to reviewing detectors I do the best I can to describe detectors to help people decide if they might be interested in them or not. Do realize again however that this review is based on preliminary information. Also, I honestly do not want people buying new metal detectors based solely on my reviews. There will be some of who want the latest and greatest right now, and I appreciate that, but being a first adopter does have its risks. My normal advice to people is to never buy anything based on a single review, but to wait for more of a consensus opinion to emerge.

      I have used the Gold Racer in the field, and I have found gold with it. Right now though if it is just a matter of you wanting to know if the Makro Gold Racer can find gold then I refer you to the excellent field review with photos posted by Ray Mills at the Detector Prospector Forum.

      In outward appearance the Makro Gold Racer resembles its immediate predecessor, the Makro Racer, but this really is a new detector, not just a Racer running at a higher frequency. Feedback on the original Racer has been incorporated as well as extensive testing and commentary from prospectors around the world. Besides the obvious color difference, major physical changes include completely redesigning the layout of the LCD display to better differentiate what are all metal functions and what are discrimination functions. All metal functions are on the left, and discrimination functions are on the right. I think the new display is more intuitive and better accommodates the extra functions implemented on the Gold Racer.

      The angle of the bend in the S rod handle grip has been relaxed based on feedback from Racer owners. The vibration mode was eliminated, shaving a tiny amount of weight and freeing up room on the display menu. The Gold Racer with stock 10” x 5.5” DD coil and NiMH batteries installed weighs in on my postal scales at exactly three pounds.

      Coils available at launch are the 10” x 5.5” DD that is stock on the detector. Optional coils include a 10” x 5.5” concentric coil, 5” round DD coil, and a light weight 15.5” x 13” DD coil.

      Let’s take a look at the functions. Under All Metal on the left side of the meter are the functions that apply only to the All Metal mode. On the right are the functions for the two Discrimination modes. The settings are independent in each mode, and once set can be saved when the detector is powered down. This simple and intuitive setup is also part of the power of the Makro Gold Racer. It is incredibly easy once each mode has been customized to flip quickly between the three modes, cross checking target responses to make a dig/no-dig decision.

      All Metal is the heart and soul of nugget detecting, and the Makro Gold Racer has an extremely powerful, smooth, and sensitive threshold based all metal mode. The Sensitivity setting is familiar to anyone who has used a metal detector, except that there are three base levels of sensitivity or gain. Significant boosts occur between 39 - 40 and again between 69 - 70. Most detectors max out at what is a setting of 69 on the Gold Racer. Settings of 70 and above are a type of hyper gain setting that takes the machine above and beyond, but in extreme ground overload signals may occur. Overload signals are indicated by a “warning siren” audio and the machine is telling you that there is either a large metal object under the coil, or that you are encountering extreme mineralization. In the case of mineralization, either raise the coil slightly while scanning, lower the sensitivity setting, or both. Overloads occurring at 70 will almost always be eliminated by dropping to 69.

      Rest assured very little is lost by lowering sensitivity to 69 or below, again, because many detectors cannot be set as hot as the Gold Racer even at their maximum setting. Do you ever run detectors and have the distinct feeling some performance has been left on the table, because the detector can always be run at maximum settings? Makro has given you that extra power for where it can be used, but in doing so they expect you will lower settings in places where that extra power works against you. Luckily, the audio alert makes it easy to know when this is. Most people do not know it but many detectors simply shut down and quit working under similar conditions with no indication at all to the operator, a situation referred to as “silent masking”.

      The threshold setting is the normal control that sets the volume of the slight audio tone that is key to any experienced nugget hunter finding the tiniest or deepest gold nuggets. The most minute variations in the threshold tone can indicate a gold nugget, and the ability to read the threshold is what sets most really good nugget hunters apart from everyone else. Makro has added a feature to the Gold Racer called iSAT, for “Intelligent Self Adjusting Threshold”. This setting consists of several levels of adjustment that vary the rate at which the threshold tone steadies itself. Higher levels of iSAT smooth the threshold more aggressively which aids in maintaining a smooth threshold in rapidly varying ground. Lower levels allow for faint variations to be heard more clearly in milder ground for extra depth and sensitivity.

      The Gold Racer can be ground balanced three ways. Holding the trigger switch under the control pod in the forward position activates an instant automatic ground balance. Just pump the coil over the ground a couple times, release the trigger, and you are done. There is a short delay when you release the trigger, and during this delay you may manually adjust the ground balance setting. The instant ground balance is neutral to slightly negative. Those that like a slightly positive ground balance need only perform the instant balance, then tap the right hand control button three of four times.

      The Tracking function on the control panel engages and disengages automatic ground tracking. This is most useful where the ground conditions vary wildly, a perfect example being mixed cobble piles or river bars. The tracking is very quick yet resists tracking out genuine gold signals as much as possible. This can also be an aid to anyone new to ground balancing detectors as it makes the process entirely automatic.

      The Backlight setting adjusts the illumination level of the backlit screen. The FD/Save setting allows adjustments to be saved when the detector is powered off, while the FD function resets Factory Defaults. There is also a Frequency Shift setting to help eliminate outside electrical interference from power lines, or another Gold Racer being operated nearby. This is set through a combination of control buttons but not visible on the menu. Finally, although this is a true threshold based all metal mode, the meter acts independently in discrimination mode at all times and indicates target id information when the signal strength is sufficient to do so.

      Under the Discrimination menu are settings that are completely separate from the All Metal settings and also saved or reset separately. Disc 1 is a standard two tone mode with low tone ferrous and higher tone non-ferrous. Disc 2 is a similar but deeper, more powerful mode. Quick switching between these two modes, each with fully independent settings, creates a many layered and subtle approach to target discrimination. Both discrimination modes are silent search, no threshold based systems. However, new to Makro models is the ability to set the point at which low tones flip, or “break” over into being higher tones. Typically 39 and lower target id will cause a low tone, and 40 and above a higher tone. This ability somewhat replaces the three tone mode on the original Racer because by increasing the Tone Break setting it is possible to create various coin detecting scenarios. For instance, all targets with an id number below copper penny could register low tone, and therefore copper pennies, dimes, quarters, and dollar coins a higher tone.

      Conversely, lowering the Tone Break setting would create a more conservative approach for nugget detecting by accepting a little more ferrous digging in return for possibly finding another nugget or two.

      The Sensitivity control on the Disc menu is the same as but independent of the All Metal setting of the same name. ID Filter is a variable discrimination control, with higher settings eliminating or blanking out id numbers lower than the current setting. This setting is independent for each Disc mode, and again flipping back and forth can create some interesting scenarios for comparing targets at completely different sensitivity and ID Filter levels. This quick mode switching between All Metal, Disc1, and Disc2, all with independent settings, is a very powerful tool once you get used to it.

      Also new with the Gold Racer is the iMask setting. I noted at the start of this review that all metal detector designs involve making trades of some sort. Extreme high frequency sensitivity to small metal targets does increase chatty false responses in extreme ground when in the discrimination modes. iMask attenuates or suppresses weaker target responses in the discrimination modes and provides a secondary level of adjustment separate from and in addition to the Sensitivity and ID Filter settings. If the detector is producing lots of quick, spurious signals in the discrimination modes, reducing sensitivity or increasing ID Filter settings or both is the first line of attack. If this does not work, go back to the original settings on those functions, and try increasing the iMask setting. If this does not work, again lower sensitivity or increase the ID Filter or both on top of the current iMask setting. iMask acts as a pre-filter giving an extra level of control to help deal with extremely bad ground conditions. Finally, Disc1 is a less aggressive mode than Disc2, so using Disc1 offers even another level of possible options when dealing with bad ground in the discrimination modes.

      The Backlight setting is independent for the discrimination modes, as is the Factory Default/Save Settings function. I think it goes without saying that there has never been a high frequency metal detector ever produced with this level of options and control. There are a lot of variables to play with here, and I would not be truthful at all if I said I have this machine all figured out. In fact, I think part of the fun with the Makro Gold Racer is we are entering uncharted territory. Until the final version of the machine is released, and until quite a few people get their hands on it and experiment, it is very difficult to say just what applications creative detectorists may find for the Gold Racer. It is a very powerful VLF gold prospecting detector, I can vouch for that. Applications also may be found for jewelry detecting and relic hunting in particular, and even coin detecting, due to the unique combination of features the Makro Gold Racer offers.

      OK, finally – some notes on real world use! Again, this is all based on prototype models and so I can only speak in generalities for this report. However, there is no doubt in my mind that even the prototype detectors rival anything currently available in a VLF detector for finding tiny gold nuggets. I can easily locate flakes of gold weighing under one tenth grain with the Gold Racer and the stock 10” x 5.5” DD coil. In fact, the machine is so hot with the stock coil I thought using a smaller coil offered minimal if any benefit, mostly because of lost ground coverage and possibly lost depth on larger nuggets. I would only use the smaller coil myself for nooks and crannies where the stock coil can’t fit, but otherwise the stock coil really is the way to go in my opinion. Keep in mind I did say grain not gram. There are 480 grains per Troy ounce and in my opinion I can find flakes all day long with the Gold Racer that weigh less than 1/10th grain, or less than 1/4800th ounce.

      In trashy locations I generally preferred running in all metal and just checking the meter for ferrous targets, which tend to lock in hard at 21 or 22 on the numbers. In theory anything under 40 is ferrous, but to be safe I might investigate items as low as 35 or even 30 depending on the situation and amount of trash. However, as I noted most ferrous locks in hard around 20 leaving no doubt what the target is. In All Metal mode very tiny or very deep targets beyond discrimination range give no target id at all, automatically meaning they need investigation. The main reason I prefer to always hunt in All metal is the extra depth and sensitivity it affords, and checking targets visually is very quick and more efficient than toggling back and forth to a Disc mode under normal circumstances.

      For areas with too much trash where meter watching might get to be a bit too much, I jnormally use one of the disc modes set for two tone ferrous/non-ferrous. Iron targets just burp away, while non-ferrous target pop out with a beep. If even that got to be too much for some people, increasing the ID Filter to eliminate most ferrous responses completely can make for a quieter experience in really trashy locations. As always, I must include the warning that the more discrimination applied, the more risk of missing a good target. Use no more discrimination than needed to preserve your sanity!

      I used the Gold Racer to hunt a couple trashy areas where I just could not go with my big dollar all metal machine, and easily located nuggets in the midst of trash. For me personally the Makro Gold Racer fills in two areas where the high price big gun detectors come up short. The ability to find the tiniest, most dispersed gold possible, both in flake form or enclosed in specimen rock. And the ability to deal with really trashy areas where good discrimination is needed.

      Perhaps the biggest surprise for me was when I decided to give the 15.5” x 13” DD coil a try. Honestly, I did not expect much from it. You normally do not see a coil this large for high frequency machines because the ground feedback usually overwhelms them, negating any gains that can be had regarding depth. Instead, the Gold Racer seemed to be even better behaved with the larger coil than with the smaller coils. I hunted some cobble piles with it and it ran smooth as can be at higher sensitivity levels. I then wandered into some moderately hot ground with it, still with no problems, and was actually surprised when I came up with a couple small gold nuggets with it. The first was only 0.8 grams which I thought was pretty fantastic. So I put a little more effort into it, and found a 0.3 gram nugget. With a 15.5” x 13” DD coil on a VLF? That is really kind of unheard of, and I was thoroughly impressed. I am not sure what is going on there but I do know the Makro detectors can sense what coil is on the detector. Something different going on with that big coil? I don’t know, but the results and performance surprised me. Also surprising was that for such a large coil it actually was not bad swinging it for half a day. That could be from my using large, heavy detectors all summer however. Still, it was an eye opener all around and changed how I think my Gold Racer might get used in the future. It looks to have more use for covering very large areas blue sky prospecting than I would have imagined.

      I would be remiss if I did not include at least a note on the versatility possible with the Gold Racer. I recently took it to a local park. Now, my ground in Reno is screaming hot, full of magnetite. The mineral percentage graph on the Gold Racer and similar machines all come up one bar short of maxed, and ground balance numbers run around 88-90. A magnet dropped in this stuff comes up with a lump of magnetite. As a result getting accurate target id numbers with even the best coin detectors past 5” is a chore. I know that sounds crazy but it is the truth. I ran the 5” DD coil and even then had to back the sensitivity down to 69 to prevent overloads in the worst areas.

      One thing about the Racer detectors that I have heard people complain about, and that is that they tend to up average target numbers in bad soil. For me this is a good thing. Many detectors will see target id number average lower in bad ground, and so fringe targets are more likely to get identified as ferrous when they are in reality non-ferrous. This is obviously not a good thing for nugget detecting. The Racer and the Gold Racer both tend to up average, and so targets like lead sinkers or aluminum that you would expect to give lower numbers often give coin like responses with the Racers. It is odd to see in practice. I got a good high signal reading near 80 at about 5” that when dug up turned out to be a common round lead fishing sinker. Out of the hole the target id promptly dropped to about 45. This effect whether by design or by accident is common with European detectors. I think it is by design because first and foremost these machines are made to pull non-ferrous targets out of ferrous trash. Improperly identifying a non-ferrous item as ferrous is the worst possible result, and so up averaging helps insure that non-ferrous items will not be missed. However, it also means these types of detectors are not as efficient at cherry picking coins as common coin detectors are. You get the coins for sure, but you dig more trash doing it.

      Still, I experimented a few hours and if you are content to live with the limitation I just described you can actually make some good finds with the Gold Racer under almost any conditions. The ID Filter works very well, and by just running it all the way to 79 it was easy for me to cherry pick a few coins though larger aluminum items like screw caps or big pull tabs often came up in the 80s also. I do think this is a result dependent on ground conditions to some degree, but really the Gold Racer is best suited for people like me who want to recover all non-ferrous targets. I prefer to hunt jewelry rather than coins myself, as one gold ring makes up for a pile of coins. And to hunt jewelry you have to dig aluminum, no two ways about that. The Gold Racer will suit me well hunting jewelry, especially micro jewelry like ear rings and fine chains.

      This report is very long, and yet I really am just skimming over the features and possibilities inherent in the Makro Gold Racer. I will close by once again noting that while everything regarding the Gold Racer is pretty much set in stone at this point, last second changes are possible. Look for more soon when the factory production models hit the street. I also get frustrated when people want information on new units, but then turn right around and characterize reports trying to provide that information as hype or a sales pitch. I have tried my best here to just present what facts I can without leading anyone to think that the Gold Racer is anything other than what it is. And that, in my opinion, is a very interesting, unique, and capable metal detector. I look forward to hearing for myself in the future what people think about it and the applications and tricks they come up with, because you pretty much need to toss anything you think you know out the door when approaching this machine.

      Many thanks to the folks at Makro and in particular Dilek Gonulay for providing me with the opportunity to be one of the first to use the Gold Racer. I admit that VLF detectors were beginning to bore me, and the Gold Racer has reignited my interest in seeing what they can do for me.

      I bought my Makro Gold Racer a while ago and finally got the chance to get out with it. It works fine around my home. The first gold area I took it too, it went bonkers with a pulsing noise and the display target  reading bounced all over the place. I was in the all metal mode with tracking on. I thought it might be EMI, since there was a massive radio tower about 1 mile away. I took it to another area away from any known towers and it did the same thing. The ground in both places is highly mineralized and variable. In the last place I turned up the iSat and that helped some. I also turned down the sensitivity which also helped some. Any ideas would be welcome. Maybe there is a problem with the detector or is it me???????
