I am using the new V3i in a place I beat pretty hard with the MXT so I have no idea of what could be left here.
Day 1: Got it out for the first time and it seemed like every program was bouncing and beeping like crazy. I wasn't digging anything just checking it out.
Day 2: Got out for a few hours in the mud. For some unknown reason it seemed to run smoother and the settings were all the same. Never had a DD coil before so pinpointing with it at tis point seems to be guesswork. Did find a penny in the driveway on top of the ground. Seems to be a lot of ghost signals still. It seems though that if i get what is a good signal and pinpoint i go to where the pp is strongest and the search that spot and it turns out to be iron.
Day 3: Another few hours. Messed with turning RX down on some programs and raising ground filters some and it seemed to quiet things down even more. Seems like pp is getting better but still have ghost holes from time to time. Haven't registered a good signal deep yet but can't wait. I did dig a quarter and a penny today. The quarter was next to trash at about 3
