Went to an old School on Sunday which was hunted out by many others including myself with my Explorer XS. When I got there I noticed cattle all around the surrounding field and to my dismay there was an active electric fence pulsating about every 4, 5 seconds. The T2 was so sensitive I couldn't even get away from the interference in the middle of the school ground. Having hunted this ground before with the Explorer, I knew where I had to go, which was about 15 feet from the fence in the far corner of the school grounds by an old well. I figured what the heck I'm going to give it a try anyways ,...interference or not. I forgot to mention that this field is notorious for old crown caps which was no problem for the explorer and that's why I used it in this particular field. I set the T2 at sensitivity 40 with discrimination at 51 and used the 3b program for elimination of crown caps(old bottle caps). I'm speechless, really I don't know what to say. The T2 performed flawlessly, even with the intermittent interference of the electric fence. I found three old pennies from the thirties and one big Canadian penny dated 1906 in beautiful condition. I identified every crown cap that there was, and even dug half a dozen or so to make sure. The big Canadian penny came in as a repeatable weak signal at 7 inches and I was surprised because I was sure it was going to break up in the 3b program as it usually does with crown caps. The T2 is an awesome machine and just keeps getting better. I've attached my findings for the last two trips I've been on this spring. I guess I'm going to have to go back and go over all the good places that I've hunted out with the explorer.
