Well its taken me 6 months of detecting to start getting 4-6 inch targets with any consitancy. How long have you been detecting? Alot of deeper targets dont give you a consistant hit on every swing. Maybe you are missing deeper signals, because there iffy and you skip over them or think there junk. The last three merc dimes i got were at 6 inches and none of them gave me a great signal. I pinpointed them to see if it was a compact target, and i would wiggle real fast over the target and it would come up as a good target. Go over an old area youve done already and found a good amount. work slowly. Find the iffy targets, try those techniques. I bet youll find plenty of stuff 4-6 inches. Now i've got to work on 6-8 inches. I asked the same question after the first 4 months of detecting, the last 2 months ive been getting those 6 inch coins. OR your unlucky Or your machine is malfunctioning or the settings are way off. Not probable. Find the iffy signals, use the wiggle and the pinpoint and dig some. If the pinpoint is spread out dont dig, if its compact and loud do dig.
