My range is in the lower field of my place and only gets brush hogged occasionally, so the grass is a foot high most generally. It is not practical to put down tarps to catch brass and I've always used an ancient (45+ years old) metal detector to find my brass. That detector no longer works very well and I'm in the market for a new one. I'm not looking for a cheap ***, but don't need to spend $500.00 either as I don't need another hobby; treasure hunting. Recommendations???
