That is the funny thing about this location. I have been hunting it for 9 years. Saturday I took the Vision to this location, to try some new settings. I noticed that I wasn't finding any buried coins, every coin I found was on the surface, down in the roots and dead clippings, but on the surface. So Sunday I took both the Vision and the T-2 to this location. I hunted with the T-2, and marked every target that sounded halfway deep, with one of those empty candy containers that I put coins in while hunting. They are bright colors so they are easily seen. Then I fired up the V, rechecked all the markers, and dug all the targets. I was so focused on seeing whether I was having trouble with the detectors that I was super surprised when I saw the coin was silver, let along a Barber. I work a grid on that area, every year at least once a year. I just think that my go to T-2, has lost some punch over the years, and my back-up T-2, which I have been using lately, is deeper because it is working the way it is suppose to.
I sure wish we would get a nice long slow soaking rain. Trying to come up with places to hunt is getting tough. Might have to brave the heat and skitters and return to the woods.
