Always great videos OBN.
Two things I can think of that I would like to see:
1) A test with the same set up shown in the video but with an arrangement of nails on the surface similar to Monte's nail board test. With the gold ring at some depth, can it be detected through the nail field without just all metal detecting the nails too? I've seen the videos of nails placed on top of a ring and it being detected clearly, but that is not what I'm looking to discover.
2) I spend the great majority of beach hunting in all metal, and when there is iron in the area, I like to have an easy switch to do an iron check on the target. Most places when in the water, the switch has to be done blindly, you know how that is! With the AQ, what mode would be the best to do a quick check against all metal response; and would you like that as an easy push button or toggle feature?
OK so it was really three questions.
Good to see there is more information coming out.
