What was your frequency setting? Multi or a single frequency? Changing to a single frequency can definitely affect ID numbers. Multi has the most predictable target ID numbers on shallower targets. Also, detecting a target on the surface or air testing with a coin really close (1” or less) can skew the target ID numbers. It’s in the online manual concerning surface targets, target ID and Multi IQ.

Too much iron bias can also affect target ID numbers and especially tones. It can also basically make some deeper non-ferrous targets virtually undetectable if running on the 600’s maximum setting of 3 in more iron mineralized ground unless the horseshoe button is engaged. That deeper non-ferrous target may sound like a broken up iron signal especially with F2=3 on the 600.

EMI………are you running your Equinox sensitivity high so that it is actually responding with tones and target ID numbers with the coil away from the ground?

Ground conditions, wet or really dry can affect target ID numbers if you are not ground balancing.

What software version are you using and did you do an update recently?

I always run in multi, ground balance with tracking on, iron bias on 0 or 1. I typically run my sensitivity between 15-20. I'm not sure which software is on it now but I have not done an update. I'll check which version it is. As far as soil conditions it varies alot here but mostly red clay.
I'm going to take the coil cover off, clean my connections, do another FP and see if there is any difference.

Thanks for the feedback

Simple hard factory presets, no GB or ANY other settings at all, test in air. That's as raw of a baseline test as it gets. If you do remove the coil cover, do it before the air test and leave it off.

Today I turned her on and did a FP and did some air testing in multiple modes. P1,P2,F1 and F2.
Clad quarters are coming in at 32-35. Silver quarter 35. Some wheats are giving vdi all the way up to 31 in P1.
P2 isn't even picking up a clad dime, clad quarter, or silver quarter. Pennies are everywhere as well with it not reading one of the wheats and coppers. Nickels seem close.
F1 and F2 sounds right but the VDIs are low with a silver quarter reading 25.
I plan on reaching out to Minelab but wanted to ask here and see what yall thought.

Ive been primarily using the 6 inch coil on my 600..and i can tell ya the vdi is crazy..its the nature of this machine..i dug a few deeper pull tabs the other day giving quater id high tone ,,

Get used to it

Were you in Multi or a single frequency when the pull tab gave quarter high tone and ID?

I always hunt in multi, my diggin buddy here on the forum sees the same ...it seems that all the targets I'd ok in air tests..but as soon as they get 3 inches deep...they can be anything...
But pulltabs hitting 30?... cmon minelab you can do better can't ya?

Sorry, not trying to jack the thread but feel the need to put my 2 cents in. I just commented on another thread on these issues.
I have been dealing with these issues since the release in Feb. of 18. I've experienced them all and think it has to be a glitch in the multi-iq. Hunting one yard in 10k I noticed it made every little piece of aluminum sound great and #s in the high 20sand 30s. And in a city park hunting in 4k same thing, pulltabs ringing 29-30. I hunted almost 6 hrs that day, dug a ton of junk and I think only 2 wheaties. They rang up pretty high also. Normally I hunt in multi unless I can't get the machine to settle down, the 4k hunt was a tryout on the latest upgrade. Also I think the more Minelab updated the worse the issues became. Face it, tradeoffs are inevitable. The company that can tame SMF will rule the roost and there is 2 knocking right now. Can't wait to see some real world tests. Mark
