Anyone into it? I was thinking this could be a fun hobby for me and the wife. Get us out of the house and doing something other then playing Candy Crush on the couch. I used to have one from Radio Shack as a kid and i remember it being fun. I am sure technology has come along way. I did a few minutes of research and it appears Garrett makes a pretty reasonably priced line up. I haven't looked into technique/locations yet. Any tips/recommendations? Anyone ever found anything of value?
