Why Only 50 Points Of Vdi?


Xergix

Recommended Posts

In most high-end metals detectors, the number of vdi points that can be displayed is 100 or more, why is Equinox scaling reduced to 50 points?
What problems could arise from this compression?
Less selectivity and more chance to dig trash?
Perhaps I-Q allowed this compression for greater selectivity?
Have they reduced the points to get more VDI stability?
I have not yet got my hands on Equinox but I plan to do some testing to see if this compression brings disadvantage in the search.
What do you think?

Welcome to the forum!

It depends on your point of view. You could argue Minelab has expanded the range based on the detectors it is directly replacing. This is one of those pictures say it all things. Bottom line - nearly twice the target id resolution as the X-Terra 705 (50 versus 28 segments), with each segment independently notchable (a new word definition?). Personally I think this is a good compromise between resolution and target id stability. I have had no issues regarding this in actual use of the detector and I can’t say that doubling the amount of scrolling and notching would result in better finds for me. But that’s just me. No doubt there are some that would like more resolution, and if so alternatives exist to the Equinox. My V3i has 190 points of resolution and if I recall correctly the CTX has 1750 separate id points.

The target IDs range from -9 to 40 arranged in an arc for better on screen visibility. The arc is divided into what I am calling "zones" (my term - I don't know what if anything Minelab calls them) for easier identification. When you notch in and out the segment will flash and the target id number will display so no worries knowing where you are.

The X-Terra 705 above has 4 ferrous numbers, and 24 non-ferrous. The Equinox expands on this significantly, to 10 ferrous, and 40 non-ferrous.

Most or maybe all American made detectors have the ID numbers on the high end of the spectrum. Minelab stops at the lower end but in all reality American made ones could do the same.

It could be less for the number of coins you had in the country where you live. We’ve got to remember we need some numbers for all the trash and too gold falls in the same category as trash.

I’m left handed but I swing a detector with my right.So I guess you could say I’m ambidextrous . So if the detector had high or low numbers it’s all the same to me.haha

Thanks Steve for the answer, I write from Italy, as you know we have different targets than the US, small coins hammered, devotional medals, and as the current currency the euro, already in the past with F75 I had problems because the range of our targets it was too tight, this made you dig a lot of trash, my concern is that this can happen also for equinox.

I dig lots of trash with any detector I have ever owned. It’s just part of the process and the secret to making the best finds. When I was in the U.K. I simply dug every non-ferrous target and I was using the F75 at the time. If I was to go back to the U.K. with Equinox I would do the same thing.

To an extent VID is pretty useless. Coming from Tesoros with no VID I learned to beep and dig... it was kind of nice not to analyze targets for 2-3 minutes before digging, I just got a nice repeatable tone and dug it. Being that rings fall all along the spectrum, you pretty much have to dig it all still...I like to take my Tesoro Compadre out once in awhile just to put the simple fun back into detecting.

Just the opposite for me unless I am digging it all. Target id is the cats meow for coin detecting in parks. Jewelry detecting is different but I can up my odds by focusing on low conductive targets. And I am learning new nugget hunting tricks with target id.

True, in field hunting the VDI may be less important, better a good tone, I always liked the two tones of the MXT, I also use it on DEUS, but on the beach a precise VDI helps and speeds up the search, EQUINOX has no visualization graphics like CTX where you can see the signal track, as well as in DEUS, a leaping VDI is an indication of the presence of trash, more points of VDI more possibilities to understand what's underneath.
Probably with 50 points of VDi a greater stability but more possibility of digging trash, even if we all know that by digging everything we have more chances of nice surprises.

Equinox can use 1-4  wireles  audio ouputs at once,-in 50 tone, so it will not be a problem to use some spectral sound analyzer in a mobile phone ... even though a good sound signal is being heard ... and then VDI...

      We do like Steve,  wife sold her nox 800 just before 3 years and ordered her new one. Showed up today and she was all excited ,put it together, charged up ready to try it out. Well the on/off switch wouldn't work!  She was a little disappointed but Minelab said send it in, so off it went !

      I have been suffering from plantar fasciitis and torn ligaments in my left ankle for about 6 months. The plantar fasciitis has cleared up on its own. The torn ligaments have not yet healed so hunting with a dig it all approach just hasn't been possible since last March. Walking is iffy enough, but lots of getting up and down is very painful. So, I have had to limit myself to shorter outings and lots of cherry picking.
      I tried an experiment using the F2 iron bias feature during my recovery for some of the parks I hunt that have high iron mineralization. I used Park 1 and Park 2 with F2=4 and just concentrated on obvious no brainer signals. Deep or shallow didn't concern me, just the quality of the response. I hunted with both zero discrimination and with half of the iron range rejected = -9 to -6. My target recovery of deeper low to mid conductive targets pretty much ceased to exist during this time.......deeper silver jewelry and coins along with any depth of higher conductive US modern coins (wheats, copper memorials, clad dimes and quarters, Kennedy halves and modern "gold" President and Sacajawea dollars) was seemingly not effected.
      Today, I hunted an exact area that I had hunted a month ago with those settings except that I hunted with F2=0 and dug every target that sounded good. I had already cleared out the higher conductive clad so none was found. I tested every low to mid conductor target from +6 to +22 (the gold and small silver jewelry range) that sounded decent using F2=0, and then switched to F2=4 and F2=9 before I dug the targets. All of these targets which were clear and obvious targets using F2=0 were beyond the range of my handheld FTP Tek Point pinpointer that was set on maximum which usually reaches coin sized targets down to 3.5 to 4" in this park. All of the targets in the photo except for the first two modern pull-tabs (bright silver and red surface finds) were recovered at deeper than 4". Some were as much as 8". They all sounded very good with repeatable signals in all four swing directions (+), and had dig me gold range numbers using F2=0. Using F2=4, all of these targets were iffy at best and the deeper ones sounded mostly like iron. Using F2=9, all of these targets were mostly iron with just a hint of low to mid conductor tones and corresponding numbers. 
      It is no wonder that I previously walked right over these targets since I had limited myself to digging only excellent sounding targets due to my injury. Even if I wasn't injured, I am not sure that I would have dug these using F2=4. No way using F2=9.
      Two of the nickels are fairly old for the Denver area, a 1949 and a 1960. Both were 8" deep and sounded very good using F2=0. The big stainless steel ring (+8) and the Avon gold plated junker (+14) were 6" deep and sounded fantastic with F2=0. The two .925 small silver jewelry items (+22) sounded great using F2=0 and were 5" deep.
      So, in higher iron mineralization, are my results an outlier or is using F2 iron bias above zero just too agressive on low and mid conductor non-ferrous targets? Comments, disagreements and Pooh Poohing are welcome.

      I hunt really trashy parks and hardly ever go after nickels because my time is limited.  I'm going to notch in 12-13 on my next hunt due to amount of wheats and silver I've been taking out of 2 places I've hit this past month. Have you found the Nox the hit nickels in this range at depth, I'm talking 7-9" depth, that's where most of the keepers are being found, thanks.

      Blank Sheet for Recording Custom Settings for my Nox 800

      OK, Ok; back in the day of my XLT Spectrum...
      ...I had a notebook full of custom settings for my records.

      Now I can convert (scan and save as) to Word Document or Adobe Acrobat to save and carry with my Smart Phone.

      Problem is, I cannot seem to find a sheet to copy online.
      I know I could create my own, but...

      HELP!
       
      Started a list to see if I have the settings in the right order.
      Does anyone have suggestions and/or corrections for the following list.
      OK; what order for the Equinox Settings Sheet???
      1. What preset program to start with
      2. How many tones; 2, 5, 50
      3. Ground balance setting and/or auto balance
      4. Setup accept/reject notches for your hunt site or hunt style
      5. Select Volume for each tone region
      6. Select Tone Pitch for each tone region
      7. Set tone break, preferably at 1
      8. Set recovery speed for conditions or accept default
      9. Run Noise Cancel
      10. etc. etc. etc.
      what am I forgetting

      I bought these headphones and used them in the ocean last week in the Kauai (up to my neck).The dealer is always busy or on a trip so I thought I'd throw this out there to get some feedback. I had a few instances where the audio cut out completely and I jiggled the cord and it came back. My question is, should the end of the headphone cord have an o-ring like a lot of my scuba equipment does? The EQ800 still seems to work fine so I don't believe any water made it's way inside detector.
                         As to my success ..well let's just say I understand why my dealer goes to Cancun for his jewelry hunts and not where I went where the waves are 3,4,5 feet. I quickly looked for beaches with "breakwaters" that you can safely take children to and I did find lots of coins and 1 silver diamond ring..but man, it was still 'surgey' as heck and not easy to lift one foot up to push scoop into sand while keeping your balance! Anyone have any experience in using the EQ in the ocean? I saw online sand scoops with a "cross" handle (like on a small shovel) where when you scoop you can keep the scoop from twisting sideways...thoughts..usage?The scoop handle would have to be a "breakdown" type to be able to pack for air travel. The scoop I took has a straight shaft that easily turns sideways when scooping.

      So, my beach season hunting has officially started. I was going to shoot for two days hunting but a wash out on Thursday made me change some plans. I had reserved Thursday for the GPX 6000 and the 14” DD coil, but had to settle for trying the 6000, 5000 and Equinox on Friday. I changed beach locations too and ended up at the less EMI beach for the day. Started out using the GPX 5000 for clearing out some of the recently deposited junk in an area that has produced silver before. I thought the storms that ripped through the previous day would remove some sand, but it was just the opposite…. sand deposited along 3/4 of the beach (top to bottom). Also, high tide reach to the highest point of the beach, so I could only hunt where the waves did not constantly reach up top. The 5000 did well considering the beach was really sanded in and gave me my first silver of the season – a 1955 Washington quarter. The rest was clad, but for 2 copper pennies. Some junk jewelry, and maybe some iron shot or just a ball bearing, - it measured .75 caliber. The big spoon was found at 20” and I thought I was going to get a beer can or some big iron, so that was a nice surprise. Hunted with the 5000 for 6 hours and decided I cleared enough to try the 6000 in that spot. The EMI was a bit more than usual but not really bad. I’m still not sold on that 14” coil. I tried both ground settings, as well as both Salt mode and EMI mode. I tried auto, auto +, manual (full) and manual (setting 1) and some in between. I just could not get the 6000  to not false on the sand. It was partially damp, as high tide receded a while ago, but with a sensitivity of 1, I would have expected a smooth clean machine. IDK maybe the coil is not good. I did not bring the 11” mono as I really wanted to see if the salt mode would work on the 14” DD. Being a bit disappointed, and after trying all combinations of settings, I called it after around 10 minutes. So, the tide was getting as low as it was going to be, so I hunted for 3 hours with the Equinox and traded my spade for my scoop. I didn’t use the Nox much last season as the 5000 was killing the silver, so the Nox sat idle. But I wanted to see if the heavy waves dropped anything on the beach along with all that sand. There weren’t many targets, so I dug everything to get a feel for all the numbers. The hairpins and tiny wire all read a steady -2, -3. The Nox did well for the short time I used it and if I wasn’t beat from the hunt, I would have stayed in the area that was producing some coins. It was the best machine for the day to give me a chance at some gold. It felt really, really good to get out and just walk the beach. Next week all 3 machines will be at the crazy EMI beach. I will have the mono coin and the DD to see if this beach (dry sand) will be ok for the 14” coil. Can’t wait!!!
