Thanks vpnavy, been looking for it online, believe that's a match. I have not found much since I started, but only been search my property for practice. A lot of mason jar lids and only one with a jar and 2 coins! Have a coinmaster GT and seems to work great, been reading other post and I may need to dig up some of my deep signals, they jump around a lot on the scale.
I have the same thing happen to my GT. the deeper the signal the more it jumps around. I need to do some test with coins and other stuff. How do you like it otherwise?
