Decided to do a Air test on the AT Pro and Gold detector's.
some interesting results, should be noted air tests are not as good as ground tests and ground tests vary with moisture, soil minerals etc.
AT Gold in
all metal mode
5x8 coil, a 1 inch in size coin is picked up at 12 inches with ease, faint out to 13 to 14 inches, need good hearing, headphones etc at 14 inches to hear a faint sound change,
in disc 1
5x8 coil you hit a max of 8 inches and no sound after that on same coin
all metal mode
11 inch coil, 12 inch good signal, signal still easy to hear at 13 inch, getting a bit hit and miss around 14 to 15 inches, tried a few coins copper to 14, silver to 15 inch if large 12 to 13 if small in size
disc 1
11 inch coil, 9 inch good signal, gone by 10 inch unless a big coin then you get 11 inch faint.
AT Pro in
zero disc, standard mode
11inch coil, a 1 inch in size coin is picked up at 10 inches loud, a bit hit and miss at 11 inches
zero disc, pro mode
11inch coil, a good sound at 9 inch, faint sound at 11, so a bit hit and miss at 12
But the AT Gold is going deep with the 11 inch dd coil, but also its deeper on both coils than the AT Pro. Another thing to note is the AT Gold is a lot deeper in all metal mode than it being in disc1 mode,
Overall the AT Gold is the deeper detector of the two. So run the AT Gold in all metal mode, using Gray ghost headphones helps, turn up threshold a bit, dig the faintest signal and you will find something deep.
