You are using three different combinations of frequencies. Different frequencies have different responses to different metals. The ID is going to be different. If you do the same test using single frequency your results will be much the same, different ID’s.
Not all zinc pennys ring up at 41. On my Legend I have a hand full of zinc pennys I use to setup my discrimation and there's a few of them that ring up at 46. I get the same situation when setting up my Manticore. I also use a hand full of pull tabs. On my Legend they ring up in the high 20s and low 30s. Maybe a coil issue or a machine issue. Hope that might help you.
Looking at your video again. You know what I think. I wonder if you put older version in and checked M1 and M2 on bullet. I bet you will see exactly what you are getting. Remember wasn’t it M3 was changed in update later on. And it works right it seems.
I found flaws with my Legend it went down the road. Something you may decide to try. Is it the shape causing the inconsistency. Might try a spent larger center fire brass round and see how it compares across the board with ID. Might even try something else cylindrical and check.
Copper is around 14 times more conductive than lead, so I would believe that M1 and M2 are bang on according to their conductive scale. I believe M3 emphasizes the lower conductive targets.
I was using a zinc penny and they are 97.5 percent zinc and 2.5 percent copper. The copper pennies usually hit around 46 on mine. Will have to read up on the M3 settings.
In park and Field modes different algorithms are run. In trashy sites M3 Multi frequency should be preferred. When a target is isolated underground, the ID will be the same in both modes. However, if the target is next to trash such as aluminum foil, Multi 3 in Park mode will generate a more accurate ID for the target.
White's Spectra V3i normalized all metal alloy targets to be the same VDI. How can a metal alloy VDI change It can't? No simultaneous freq./kHz shows the various freq./kHz in different frequency to indicate a nickel is a nickel normalized other than the V3i? In reality they provide very little information other than: Beep, Beep, Beep. The operator becomes frustrated, stating my detector is 'chatty'? Is that what you are experiencing? Thanks for the video.
If I remember right you could turn off the normalization on the V3i if you wanted to. The metal detector runs fine its just that the ID's are not consistent over different frequencies. So if I wanted to hunt in M1 my large civil war bullets would come in at an ID of 30-31. This is the same range as those ring pull tabs. It wouldnt be so bad in less trashy areas but I normally hunt public areas and there are hundreds of trash targets that fall into that range. If I hunt in M3 then then the IDs are back up in the zinc range. It would be nice to have a consistent ID no matter which frequency you were in.
@@DirtFishing You are correct. You could turn it on and off. White's Spectra V3i Advanced Manual. With Normalized unchecked, V3i will report the raw VDI numbers for the frequency mode selected. There is at least one situation where this is an advantage. At 22.5kHz the lower part of the non-ferrous VDI range is expanded, resulting in more numerical separation of low-conductive targets. This can help in separating nickels and jewelry from pull tabs. Here is a table showing the difference in normalized versus un-normalized VDI’s for a number of targets:
Thia Way You Should Never Relic Hunt Using Machines With VID Numbers, Meters. You miss Small, Lead, Small Brass, Gold Coins. Audio Will allway tell you "Truth" by it tones, but today hunters are lazy to try "Cherry Pick' targets vs Hardcore Relic Hunter that hunt non VID/ Meters Detectors and find that Hi _Tech Machine Miss!
