Thanks Therover, the vid was great! even though I cant get my sensitivity to full I still get awesome depth, I just received the 11 dd today and WOW I air test a 1.2 gram nugget at 6 inches and a silver dollar at about 13 to 14". Your right about target separation Ive taken nails and checked for recovery speed as seen in you tube vids. first thing I noticed was fisher was in a class all its own!
I took it a step or two further. I can line up 4 nails and stick a nail through a gold ring and two nails after, set the disc to ignore the nails and still get the ring. Ive had my gb for 8 months and it amazes me the amount of targets Ive dug from under nails. Today I played around on a old road for relics I found several horse shoe and shoe parts but one I got was about 15 inches down and was only a small part of a oxen or mule shoe, this might not sound so amazing but two days before i was playing with my sand shark In the exact area and didn't have a clue it was there. Dave Johnson has said this machine has the best front end he has ever designed HANDS DOWN. (THANKS DAVE) Now that they are getting on the market I am pleased to see other detectorists feeling the same way. As far as the sound modulation I am kinda thinking I like mine the way it is, the computer assigns a tone at a set volume. I get a strong signal on targets that at the same depth in all metal are just a whisper. Its one sweet little machine for the $$$. Next on the list is a ski run that has not been used in over 50 years. It was a small tow line but was used allot back then. Sorry this is so long winded !!
happy hunting everyone!!
