Been trying TTF lately and am somewhat pleased. No great finds but I have noticed stronger signals from the lack of disc. that I have been using (relic mode). I think that I am going to try this at the beach this year--I really believe the depth will be increased and since I usually dig just about everything else at the beach--why not? Instead of a null on iron--it will be a low tone---Anyone else tried TTF at the beach? Good or bad--Comments please? P.S. Goesforever and his vid got me interested in TTF--give credit where credit is due
