Most of the time I'll be looking on the mainland and the beach occasionally. An example of the type of coins that I'm trying to specialize in finding are the St. Gaudens Double Eagles. I suspected that nugget detectors would detect these coins, but from the research I've done so far those types of detectors appear to be much more expensive than my current $1,500 spending limit. I am interested in the Garrett 2500 because I heard it can detect up to 15 ft. deep but I was told this machine would have difficulty locating only one gold coin at a time, especially at that depth. What price range am I looking at if I want something that is going to give me a good reading at up to 15 ft. on a gold coin? 7ft. on a gold coin? 3 ft. on a gold coin? and finally 3 inches to a foot on a gold coin? With just $1,500 dollars to spend am I stuck in the 3 inches to a foot club for now? Thanks to everyone for their time, it's as good as gold in my book!
