I recently bought a gamma and it's on its way. Excited by all the reviews, my father and mother are dedicated to whites, but I hope to change that to some degree. I have two whites myself, the coinmaster 5000/d , my favorite but getting heavy since I have a bad back. I haven't seen as much in the forum on the gamma as I'd hoped. I plan on adding my two cents and videos about what I find both in the ground and with the machine. Thank you guys for a place to learn, discuss and help.


10K registers solid 60 no movement + or -
and proceeded to check it out. I swung over the target in both directions and the signal was consistent. Then I bumped up the sensitivity to 80 and the tone got better and locked at 89. I pinpointed the depth at 7". Before I dug the target , I set the volume down to 4 and removed/unplugged my headphones. I swung the coil over the area again and there was no tone at all. It is hard to run the Gamma at a volume of 10 with no headphones because: 1. it is annoyingly loud 2. you will kill the battery alot faster than running with headphones. This really supports the suggestion of using headphones and running the volume at full with the Gamma.
