I used the little BBS 800 coil on the Sovereign for today's hunt.There are a lot of Sovereign users that just don't think this coil performs very well,including myself until after today's hunt.The park I hunted had an abundance of trash and the little 800 coil was great the way it separated the targets.A lot of the wheats I dug had a very strong clear signals at a depth from 7-9 inches no wiggle even required.The silver dime was next to a screw cap and could see the meter move from 178 to a nice clear 180.After I centered the coil over the 180 reading area the 1959 Dime was at a depth of about 6 inches in roots that had to be cut and yep even with the S1 probe I nicked the dime.I have always liked the Tornado 800 and was very surprised how similar these two coils are in performance.Anyway I found 8 wheats in the 40s and 50s and a silver Roosevelt.
