I have a Radio Shack 3000 also a swap meet $40.00 special. I also have a White's Prizm II which I use a little. I do not like the touch pads and pinpointing. Most of my finds have been with my $10.00 swap meet special of Radio Shack 1000. (Bounty Hunter Tracker IV). It has a real meter and very basic. I often cover a lot of ground in playgrounds, lakes, parks, and forest land. I hunt in my local small communities and keep a small profile. No digging in the grass. My machine works on dry soil, wet soil, sand and in the water of fresh water lakes. Have found lots of coins, some jewelry, silver - my best a 1900 Morgan silver dollar. Also hundreds of old soda pop bottles when the lakes were at their lowest. The areas that I keep returning to and have cleaned most of the trash I detect on all metal. Find nickels and relics that way. In most of the areas I have been the only one metal detecting. Not many people here in the mountains with metal detectors. I think they are looking for the big hits. Gold nuggets from old mining, etc. Gretchen.
