Thanks for the tips - I've been using my GT, and all I can say so far, is the more I use it, the more I learn; the better I'm getting at using it. I still have a lot to learn, but I'm finding things in places that I haven't found anything before, or has been hunted hard in the past. Getting a lot of coins in the parks that are so crudded up, the buildup is like stone on them (a lot of lime stone in this area). I got Ron's Meter, and like it a lot. I haven't adjusted it as it seems to be right on, I just need to learn to use it with the GT and learn the sounds better - it gets tricky sometimes - a flattened beer cap fooled me the other day, it was so flat, there were not ripples in the rim at all, and it sounded different than other bottle caps. Usually I can tell if it's a bottle cap or not, but this one fooled me. A dime and penny sound similar to me too, unless I lay one of each on the ground and listen to them side-by-side, then I can tell the difference. It's coming to me though. I got an S-12 and an S-5 to use with it, though haven't used them just yet. I had a good deal, and got pretty much everything I think I will need, other than experience - I have to earn that one.
Good luck and HH.
