I used to have one of these.
Anyway,,yesterday,,,was using my brother's unit to do some testing,,on some scenarios using nails and coins.
He was setting it up like he usually does,,,for best settings for unmasking in around iron and nails.
He said he usually uses ground tracking on.
Well,,,I discussed this with him a bit.
So we using what he thought was the best way to set up,,we tested.
Here's what I saw.
If you use a tracking ground balance,,,and have speed adjusted say correctly,,,this using tracking ground balance---I don't recommend.
Why??
What I would do,,is sweep the challenged target scenario,,,then sweep some adjacent junk targets and iron setting off to the side about 16" away,,,and then moved back over the challenged target scenario.
Most times V3i provided no detection on challenged target with first pass of coil,,sometimes even as many as 4 passes of coil.
If I continued to sweep the challenged target scenario,,eventually the detector would start to detect the coin by nail scenario.
Thought I would share this info.
I highly recommend if in trashy site,,or site with lots of iron,,,lock your ground tracking.
Otherwise,,you run risk of leaving some finds in the ground.
