Had my first trip out with my GT today. The detector arrived around low tide but I had to test it in my test garden first. I tried the 8, 10 and S12 Intruder coil on small to large gold. The 8 and 10 coil came close with the 8 being a bit more sensitive on really small gold. The S12 Intruder wouldn't pick up the really small gold so I decided to take the 8" coil to the beach. It worked just wonderful. I found that the 8" would give a sigal even if you get close to a target and sure wasn't as heavy to work with. It was a little over a hour after low tide when I got there and not many people on the beach because of weather. I managed around two bucks in change and this cross and chain. I have to say there is a difference from the GT and my old XS 2A pro. It is more sensitive on small gold. Anyway I'm a happy camper to have a Sovereign back in my stock pile.
