I've been blessed with lots of finds with the 1500. I started out with the GTA 500. It was kinda wobbly and unstable with lots of sensitivity. It too found lots of coins, especially pennies. I think I have mastered the GTI 1500, as I have found over 40,000 coins with both these Garrett Machines. I also have to give credit to Charles Garrett's Book "The New Successful Coin Hunting", which I have read several times. His knowledge, ideas and technical information really put this art of metal detecting together. I also like ALL types of hunting, to this day. I flip around hunting boulevards, schools, sportsfields, old homes, in lakes, around lakes, in the woods, ski hills etc. Thay all have their unique types of finds. And of course making time to hunt. Hunting every day for at least an hour a day adds up over a year. What a great hobby!
