There is no one model or companies detectot that is good for everyone in every situation. Right now, I'm pleased with my Garrett AT Pro which I think offers the best bang for the buck ($595 MAP price). In the past if a detector couldn't tell what something was, I left it. Others said dig it all, because meters lie.
With the Garrett AT Pro, I set it up in STD mode, coins program, iron totally rejected, sensitivity 7, did manual balance. Very quiet and stable. Got a loud beep & #s said 80-85 (dime) & gave depth as approximately 8 inches. Had consistent high tone. At 7" in dry, hard, mineralized soil, I found a clad dime. Probably sat there 20-30 yrs in heavily detected park.
It can go underwater to 10' & no worries if it gets rained on.
It doesn't feel too heavy at just over 3 lbs including the 4 AA batteries. DD coil does good at separating closely spaced objects. The Pro mode can detect a coin under a nail, I'm told. It's very good at detecting/IDing
nickels & has increased sensitivity to gold, compared to most detectors.
The Garrett Ace 250 I had, with stock coil, never IDed a dime properly for me beyond 4", so the AT Pro is a big improvement.
I've had the MXT. It got me a couple 6" deep dimes that IDed good in the same park the AT pro got 7", but think ground was wet, as normally the White's didn't ID properly beyond 4"-5".
I've found very few detectors that can give a corrrect ID at beyond 4"-5" deep in my soil, so 7" is deepest coin found. Best wishes, George (MN)
