Nice finds. How deep?
Looks like to minelab is doing the job for you. Just remember that anytime you go back to a site, swing in a different direction. This simple act can allow targets that were once nulled/masked to become better targets and more detectable.
Congratulations on the nice coin shooting!
The Minelab 705 in AM mode is a very deep machine.
Are you using a X-Terra SEVENTY, or the "705?"
