The temp this afternoon was in the upper 70's, I took the etrac to work with me, so after work headed to a peacan grove by the walnut river in Winfield KS, for a short hunt. There's a lot of camping during summer in the grove. Found a good pile of change, all clad, a key, and a nice silver ring marked .925. The ring was about 5" deep, from the signal it could have been a foot deep and the etrac still would have picked it up. Seen where Digitrich said in a post that he ran in manual just a couple of numbers higher that the suggested sensitivity, usually I run in auto, but I gave manual a try, adjusting as needed to stay a couple of numbers above. The etrac ran any where from 17 to 26 on sensitivety doing this and ran smooth the whole time. The times before that I'd tried manual I'd set it on 25 it would get noisy, and I'd switch back to auto. In manual targets seem to hit a bit better than in auto, I'll have to try this some more at other locations. HH ken-ks
