V3i Vs MXT Pro And Some Of My Thoughts This Week...... Asking For Some Of Your Thoughts


Recommended Posts

Have recently got a hold of a nice V3i......I had one about 8 years ago and I decided back then it was not for me. I have Been comparing a MXT pro to it. Straight out of the box the MXT is way faster on recovery and obviously way easier to set up.

With the 6X10 DD coil the V3i cannot see a penny about 1-1/2 inches from a piece of iron.

If I put the same coil on the MXT it picks it right up. Very well actually.

I have fiddled with the V3i on and off for a couple of days. I am on the fence about hanging on to it. I have been talking to a friend here locally who swears by the V3i and it is his go to machine. He told me that once I get it figured out it is deeper than the MXT.

I guess that is possible.

I am not a fan of the D2 coil as much as the white 6X10 DD coil. With the white 6X10 DD coil on the mxt I can hit an 11 inch nickle in my test garden with just turning the gain up.

With the same coil on the V3i I have to go and adjust the ground phase and the recovery settings plus SAT as well....Sorry I do not know what all they are called but it used to be pre and post gain or AC and DC or whatever was on the XLT and such. Plus there is also the transmit gain and all that too that I can adjust and I am trying to just hit a 11 inch nickel with the V3I!!!

I have messed with the recovery speed and the internal filters and have managed to get pretty satisfactory results after lots of hair pulling and time out in my back yard.

I paired up the 13" DD Coil to the V3i. It made the machine way more sensitive without hardly doing anything else to the settings. It is like a match made in heaven actually on the V3i.

I normally am a turn on and go kind of guy. I guess once the V3i is set up the way I like to run a machine it would become a turn on and go unit.....It will just take a bit to get there.

I am on the fence kind of. I know there seems to be a little more action here with a few of you who still use a V3i so I am going to ask, is there any way the V3i can be adjusted to be as deep and as fast as the MXT pro??

If not I may just wind up selling both and sticking to lighter machines....... Had a blast with my Equinox yesterday!!

If you have a 13 "ultimate coil on the Spectra V3i ... then you don't have to worry about the depth of detection ...

My recommended base setting for a good depth on the Spectry V3i... is  :
3F multifrekvenci-Best data program Hi-Pro ... Mix-mode, .. Ground filter - 7.5 hz Band /High filter, Recovery delay 70 .., Rx Gain 10-12 .. Tx -Bost Off, Allmetal 85, Sensitivity DS 88 -93 ..., Modulation OFF .. bottle cap reject OFF ..

If terrain conditions allow .. slight mineralization of the terrain ... you can try using RxGain- 6-7-8 with TX Bost ON ..

If you cannot use such a setting. -for example if you have a medium-mineralized terain.. just set RX Gain to 7-10 without TX bost ... and change the ground filter from 7.5Hz Band / High  groun filter to 10 Hz Band / High  ground filter...

Thank you. 

 

Yes the 13 inch coil is good on depth. 

 

I am still trying to get the recovery speed up to par. 

Am trying to like the unit. It is a nice and pretty one. 

 

Maybe if I forced myself to only use the v3i I would not ask so many questions !

If you want depth and speed, the Ultimate 13" coil on the MXT is a great match.  You shouldn't have to work this hard tweaking a machine to get what you want (unless you are simply enjoying the tinkering - which is what the V3i excels at most).  You are comparing the V3i ultimate depth to the MXT based on something someone said.  Yet you have a perfectly capable MXT sitting right there that can get it done and be deep with that ultimate coil.  Is the infinite tweakability, spectragraph, and MF worth it for what you want to do with it considering what else you have in your arsenal?  If you are enjoying the challenge and tinkering, that's one thing.  When it turns into frustration, that's another.  To me the MXT was a high water mark for Whites in integrating capability and tweakability (love those analog knobs) of key parameters with relative ease of use.  A classic.

I think maybe I am enjoying the challenge possibly.  I kind Of want to keep the V3i. .

Your correct about the mxt pro just being a workhorse with the best and easiest set up there is from the whites line up.

Not to mention battery life compared to the V3i. No comparison whatsoever.

What I have noticed is the programming throughout the different programs are different internally.

It does not seem to carry the same parameters across the board.

There are many more choices in mixed mode pro to adjust than in coin mode.

I found that out today.

So it looks like the ultimate find everything mode is mixed mode pro I think it is called.

Therefore, I recommend Hi-pro .. Best data. + set to Mix mode .... it's one of the deeper programs ... with low discrimination that works OK ... out of the box ..

   If you have doubts about how to set the recovery delay .... then in my opinion the optimal value for coins in the depth somewhere is between Recovery delay 65-75 .... this applies to every coil size you use ...

Don't be afraid to add DS sensitivity to at least 88-90 ... and you can go to 93 ... if the conditions allow.

On small 7 "coils you can certainly increase to DS 95 .... and the detector will process satisfactorily ..

set the sensitivity of Allmetal ... 80-90 so high .. that it alerts you to the target on deep signals .. which may be beyond the reach of discrimination ..


If you want to be more certain ... bury a few coins on your terrain at the depths of the depth and check your settings in such a test ...IMG_20200329_181024.thumb.jpg.b850793c4c194377dbf841bde18d9e91.jpg

It looks like you know the V3i inside and out. I like how the mixed mode acts but I am going to have to tweak a lot of settings on it.

Yes I have a pretty good test garden. That is what lead me to start asking questions on the V3i here on the forum. I could not get the V3i to hit a copper coin about 1-1/2" inches from a piece of iron in the ground with the D2 coil and the 6x10DD coil.

But it will hit the coin next to iron with the 13" DD ultimate coil without much parameter adjusting.

I wanted it to be as fast on recovery speed as the MXT is however I do not think it will be possible. I do have it way faster than the stock programs is though.

 Spectra V3i ... in Mix mode and SAT set to 25 and more ...., and Recovery delay to from 20 to 33 ...... is a faster responding detector ... in this case better separation use Ground Filter 10hz band / high, or 12.5 Hz Band. Filter .. and you will still get an acceptable depth ...

12.5 Hz high The filter is the fastest Ground filter..but it is already visibly shallower in range .... than other Ground Filters .... of course, due to the strong separation, the loss of depth does not matter ..

 For good separation, always set the Bottle cap to OFF ... ,,, it is a similar function .. as the Iron bias setting for Equinox ..

      I am a big fan of the White's SignaGraph display. A version 1.0 was originally developed for the Eagle Spectrum. The Eagle Spectrum underwent a complete hardware revamp, and was renamed the Spectrum XLT. A more refined version 1.1 of the software was matched up in the XLT with a much better LCD display. The SignaGraph was also used on the DFX, and was largely the same as on the XLT, with the addition of multifrequency options. The SignaGraph was later greatly enhanced on the V models (Vision, V3, V3i, VX3) and renamed the SpectraGraph.
      The genius of the SignaGraph/SpectraGraph is the ability to display multiple target id numbers at the same time, and even to choose how the target id number is determined. Here is the SignaGraph explained by its designer, engineer Mark Rowan. More details can be gleaned from the White's XLT User Guide.
      Spectrum XLT Engineering Note
      The SignaGraph™ "Phase Spectrum Analyzer"
      by Mark Rowan
      Some time ago, I had a conversation with an avid treasure hunter whose instrument of choice was White's Eagle II SL 90. He described to me a technique with which he could discern pull tabs from rings, nickels, and other desirable targets by listening for some subtlety in the audio response. Then he asked me, "If I can do this, why can't you program the Eagle's microprocessor to do it?" My response was, "If you can do it yourself, why would you want the microprocessor to do it for you?" I mention this as a means of illustrating what I consider to be the metal detector designer's fundamental dilemma, which is, as Prince Hamlet might have phrased it, "To beep or not to beep". More specifically, if you're faced with a target at some depth in badly mineralized ground and the detector has a hard time getting a solid reading on it, what do you do? If you design your detector to ignore the target, and then someone comes along with their El Cheapo brand detector and digs the target, which just happens to be a $10 gold piece -- you're in big trouble. If, on the other hand, your customers find that they're spending most of their time chiseling through eight inches of hardpan and finding bent nails and wads of aluminum foil, you're not much better off. The point I was trying to make with the gentleman who had devised the clever pull tab discriminating scheme was, that if you put too much of that kind of "intelligence" into your metal detector, there are always going to be those targets that you miss because the machine got fooled.
      Which brings me, of course, to the newest White's model, the Spectrum XLT. The Spectrum XLT has all of the features, performance, and flexibility of previous members of the Eagle series, plus a new display which makes the instrument remarkably easy to use. It also makes use of a new way of displaying information about targets -- the "SignaGraph™ or "Phase Spectrum Analyzer" -- which shows the operator everything that we currently know how to display about the characteristics of metallic objects in the ground. In this way, we have gone a long way towards addressing the dilemma I mentioned earlier. The Spectrum XLT is a very "smart" detector, but it is also an "honest" one.
      Having done the best it can to determine the probable identity of a target, the Spectrum XLT gives you all of the information you need to make your own decision (human beings are, despite what you might have heard, still a whole lot smarter than computers) to dig, or not to dig.
      Before I begin to describe in some detail what the SignaGraph™ is and how it works, I should emphasize that you don't need to know how it works in order to use it effectively, and that the best way to learn how to use it.... is in the field. In a very short time you will begin to recognize certain display patterns as being characteristic of certain types of targets. I should also point out that even if you ignore the SignaGraph™ altogether, this instrument still has the audio discriminator, V.D.I. number, that its predecessors had, plus the icons, and some significant improvements in terms of weight, physical size, and ease of operation.

      White's SignaGraph display
      For many years, White's has built detectors which identify targets based on a V.D.I. number (V.D.I. stands for Visual Discrimination Indicator) which characterizes metallic objects according to their size, shape, and composition. The V.D.I. scale on the Spectrum XLT runs from -95 to +95. Large positive numbers typically indicate objects which are good electrical conductors; for example, silver dollars will come in at 92. Smaller positive numbers usually indicate objects which, because of their size, shape, or composition, are not as conductive; nickels will read about 20 and aluminum foil may come in near 5. Large negative numbers are typical of targets which are readily magnetized, but which conduct electricity poorly or not at all. Some sands or soils which have a high concentration of ferromagnetic minerals may read -93. Metals containing iron have both magnetic and conductive properties, which causes them to spread over a wide area of the scale, although most typically iron objects will fall in the range -30 to -75.
      The V.D.I. reading is an excellent way to determine the identity of most commonly occurring targets, although I might mention in passing that the only 100% reliable discriminator is called a shovel. However, as a famous metal detector engineer once said, "Life is grossly unfair" (actually, there is no such thing as a famous metal detector engineer, and life really is fair, it just doesn't want anybody to know). For one thing, the signal which a detector receives back from even moderately mineralized ground is typically much stronger than the signal it receives from the targets buried in it. This makes determining an accurate V.D.I. number for a target at any substantial depth a very challenging business indeed.
      Furthermore, some targets will cause an abrupt change in V.D.I. response during the course of a single pass under the loop; the most notorious of these are the dreaded bottlecap and the dreaded small piece of foil near the surface in bad ground.
      Enter, as they say, the Spectrum XLT. The SignaGraph™ is very similar in some respects to the familiar analog V.D.I. meter. The display is calibrated from left to right in V.D.I. units, from -95 to +95. When the loop is passed over a target, a V.D.I. determination is made, and a vertical bar is placed at the appropriate place on the scale; near the right end of the scale, say, for a reading of 78. So far, this is just what an analog V.D.I. meter would do. At this point, the similarity ends.
      An analog meter can indicate only one value at a time; with the SignaGraph™, up to 30 readings can be displayed simultaneously. Also, the vertical height of the bars in the display has significance; the height can either be used to indicate signal strength or a running total of the number of readings at that point on the scale ( the operator may choose which of these two indications is to be used). The advantage of this type of display format becomes evident when the loop is passed over a bottlecap or some other flat, thin iron object.
      Although the instrument may respond with a loud, clear audio output, and the V.D.I. readout may register a value near the upper end, the SignaGraph™ will tend to "smear out"; numerous segments will appear throughout the display, many or most of them in the negative (typically iron) range. Try the same things with a coin, and you won't see the "smear"; typically you will see 1-3 bars grouped closely together near the top end of the scale. If any smearing does occur, as it might on a deep coin in bad ground, the more accurate readings will stand taller in the display and will tend to persist from sweep to sweep.
      Another unique advantage of the Spectrum XLT is the ability to make use of information gathered during the course of multiple sweeps of the loop. For years, clever detectorists have realized that by passing the loop over the target repeatedly and mentally keeping track of the range over which readings appear, and the most frequently occurring numbers within that range, they can achieve the highest possible accuracy on really tough targets. The Spectrum XLT performs this operation automatically.
      The standard mode of operation is the so-called "Graph Averaging" mode, in which a continuous count is kept of the number of readings that fall into a particular slot in the graph. This might also be a good time to mention that more than one V.D.I. determination is made during the course of a sweep; sometimes as many as 6 or 8 readings will be taken during a single pass, so it only takes a couple of sweeps for the effect of averaging to become significant. What you will see in the field will be a single bar on the display which will "grow" until it stands out prominently above the other bars on the display.
      Although it is not necessary to adjust them, there are a number of controls that allow you to customize the way that the graph is displayed. It can be set up to clear itself on each sweep of the loop, if you find that too much information is persisting in the display for too long. Or, you can configure it to let the vertical bars fade slowly out of view. Even the rate at which this fading takes place is adjustable. If you don't want to be bothered with any of that, then don't be. The factory preset settings should work just fine for almost anyone. For those of you who want to know an explanation of Accumulate, Average, and Fade, one is included in this Guide.
      If all of this sounds confusing or mysterious to you, allow me to put your mind at ease. The Spectrum XLT is one of the simplest-to-operate detectors you will ever use. I shall describe just how and why it is so easy to use momentarily; but before I finish talking about the SignaGraph™, I want to say it one more time-- you don't need to be a Nobel Prize candidate to figure out what the display is telling you. The usual response from somebody seeing it for the first time is something like: "Okay, I get it now. Now leave me alone and let me hunt!"
      What is it that makes the Spectrum XLT so easy to use? The key is something that is known in the software business as a "menu-driven interface". To implement that, we have used what is known in the display business as "A True Graphics Display". What all of this means to you, the user, is that all of the controls and options are listed clearly in plain English on the display. A flashing arrow appears on the screen next to one of those options; you can move the arrow up or down with the two "arrow" keys on the 5-key touchpad. When the arrow is next to the control you are interested in, you push the ENTER key. That is everything you need to know to run this machine. If you are like me and you hate reading instruction manuals, I believe I can safely guarantee that you will be able to operate the Spectrum XLT successfully your first time out without ever having to open the cover -- although the manual should be extremely helpful if you want to fine-tune the performance of your detector by adjusting any or all of a rather lengthy list of professional options. Incidentally, another name for this method of running a machine is the "point-and-shoot" method; you point at what you want, then "shoot" with the ENTER key to make it happen. Finally, for those in a hurry, there are a number of "shortcuts" designed to make accessing commonly used features as fast as possible.
      What makes the Spectrum XLT even easier to use are the factory preset programs (like those in previous Eagles) which you can load with just a few simple keystrokes, following the prompts in the display. These programs configure the machine automatically so that the beginner or casual treasure hunter can expect a great deal of success over a broad range of conditions.
      Any attempt on my part to detail all of the advanced features and controls which the Spectrum XLT has to offer would probably leave me with blisters on both of my typing fingers. Suffice it to say that all of the features we have had in previous state-of-the-art detectors are here in this one, plus several new ones. Most of the features are there because somebody asked for them -- the moral of the story being, keep those cards and letters coming, and we will continue trying our best to give you the kind of detector you really want.

      Very good post by Mike Hillis at Dankowski's on V3i filtering options and how they affect performance.
      Older designs often refer to having "two filter" or "four filter" methods. Here is a post by Monte that discusses that subject. See also "Ground Filtering" in the DFX Engineering Report by Mark Rowan.

      So if a man wanted to have a faster recovery speed on a V3i in coin & jewelry mode for a trashy area how would one go about that??
