The original analog Goldbug and the reintroduced version were great detectors for small nuggets. I lost mine in a fire. I now use the Surfmaster
PI by Whites. It is 15 years old and still produces. It scans deep and fast. I use it on the beech also. It picks up coins and rings right thru black magnetic sand. I have found boat anchors at 4 feet. You just turn the two dials to the preset positions and hunt all day. No messing around with recalabration. Just my point of view, Frank
