Custom M6 Coin ID Chart!

[Critterhunter]

Two friends and I just scanned in a bunch of coins today on the M6. Here's the VDI chart for them. We also scanned in well over 100 or 200 gold rings and made a VDI chart for those too. I'll be posted a seperate thread on that with more information in a little bit here. If you have any other coins on the M6 to add to the VDI list below please post them for people.

Jim just bought an M6 and I'm considering one to add to my line up. Both of us would like to thank Fern for helping us scan in all those rings he found with his Excalibur as well as these coins. We made quite a team. One guy sweeping targets over the coil, the second guy reading the number, and the third guy punching it into the spreadsheet.

The charts are great, I am planning on ordering a M6 this comming Monday. You fella's put alot of time & work into it. Would you mind if I posted your charts on another forum that I visit frequently, I'm sure alot of others would appreciate it. Thanks again for the charts. Steve.

If anyone relies too heavily on the VDI's, you will be missing some very good targets. Deep targets in the ground could be off by 30, 40 or 50 VDI numbers depending on many, MANY factors. VDI's.....use with caution.

Good point Larry.

Yea, most of us know that VDI's can be off in certain ground conditions. That's why I tell people to dig a few targets at a new site first to see where things are reading at depth. I've ran into sites where silver dimes read like zinc pennies and so on. Still, in most situations a coin should give you a good ID unless at the fringe of detection, masked by junk, or in very heavy minerals.

Go ahead and post that chart where you like. I'm going to re-do it in a better format that makes things easier to follow, though. A chart you'll be able to carry in your pocket. Tape it onto a piece of cardboard and protect it with clear box tape so mud just wipes right off in the field. I'll post it tomorrow probably. It's similar to one I did for the Sovereign GT a few months back. It'll list things like pulltab ranges, common trash target numers (shot gun shells, 22 casings, screw caps, etc) as well. It'll be more clear than the above chart with targets listed in order of VDI number as well. See the splitting hairs on rings thread for info on the pulltabs and rings that this chart will list as well in a more compact fashion.

hope you will add the ring chart too thanks

War nickles are jeffersons too, and then again all nickles could be called clads, so there is a distinction there.

Here's the initial rough draft of a chart you can carry with you. It's way too long at the moment but that's because I left stuff in there from the Sovereign GT chart to remind us to scan later on the M6. Most of the trash and other target listenings will get condensed down later. I noted where to cut it in half so you just have the coins/rings lower half. The top trash section is useless at this point. Throw that away. Load the chart into paint and stretch/skew it into a size printed out that you feel comfortable carrying if need be.

If anybody has any further coin numbers please post them here and I'll add them on the next update.

Yea, it should work with the MXT as well but I figured it's time the M6 snubs the MXT in name recognition here and there. Plenty of threads on the MXT where no mention is made that it applies to the M6 as well. I don't need the prospecting mode and the re-label of targets for relic hunting is pretty much useless since you should be going by the VDI # anyway if you need that kind of information. The only feature on the MXT I'd like to see added would be the notch and a threshold (think you can turn that up inside on an M6, though). The sensitivity/audio boost mods for the MXT look interesting but I have a feeling they might work with an M6 as well. Seems like most of the differences between them is software but haven't researched that yet. Even wonder if there might be a notch function hidden away on the M6 board needing only the external pot, if it shares much of the same hardware. Either way, the M6 has everything else I need in a coin/ring/relic machine, and more tones than the MXT unmodded. I'll either buy a cheap used MXT and add the tone and other mods or just pick up a used M6. Either will work well for what I need in an addition to my line up of machines.

By the way, the current tab range (see splitting hairs on rings thread) is 20 to 37 but that's showing every tab number from our test pool instead of listing what number range to avoid to block out most of them (say 84%). I found with the Sovereign GT that only 8 percent fell onto the first three or four numbers and the last three or four numbers. More than likely you could just avoid say 23 or 24 to 33 or 34 on the M6 (instead of 20 to 37) and avoid roughly 80+% of the round/square tabs liike the pattern showed on the Sovereign. We're going to post exact numbers when we re-scan them to graph the percentages.

The Sovereign found a 20 digit wide window for the test pool of random round/square tabs. Scanning the same tabs with the M6 found a 17 digit wide (20 to 37) window of all those tabs. Using a less wide window on the GT blocking out about a 12 or 13 digit wide window (size of GT's notch) of those tabs (instead of 20) kills 84% of them. This window starts roughly 3 or 4 digits in and ends 3 or 4 digits before where the 20 numbers fell on the GT. In your head you can kind'a do the math and figure out where that would be on the M6's 20 to 37 window of tabs as described above. Slight adjustments up or down to fine tune it for your site will avoid most of them while still recovering the majority of rings.

Well have mxt good machine needs tone id digital discrimination or notch back lite.The prospecting mode gos deep and you use the iron content to see if good target.Never tried m6 good machine.But the chart is close to what i have on xlt.I was just looking this morning have you noticed if good target are odd numbers more than even numbers?I started to notice this on xlt numbers go +1 to +95 but most target come in odd numbers around here.

 

[ohio fred]

i see this chart has a lot of even numbers my number on good targets on xlt are more odd numbers.On your chart you have i believe 6 odd numbers good targets i believe if i counted 14 even numbers good targets.Just checking numbers to figure out a program or what to be more aware off.Was that the ring chart in post below or are you redoing it?

 

[Critterhunter]

The ring chart in the "Splitting Hairs On Rings" thread is the one we just did on the M6. We had scanned in just about all the same rings on a Sovereign GT and made a chart for that a few months back posted in that forum. What I was saying was the pulltab percentages and ring numbers in the coin chart are/will be derived from the ring chart so you can carry that info with you for quick reference. Just need to put the percentages for the tabs in on that chart above. It will eventualy show what range of numbers 84% or so of all tabs fall into, with the other 8% at either end of that window as it's listed above. Don't have that info for the M6 yet. Just that all of the tested tabs ranged from 20 to 37. Hope I'm making that clear enough this time for people.

Maybe it's just me but the charts are fuzzy and I can't read them, is there a way to clear them up? Thanks.

Just click once on the chart and that will magnify the lettering .
