I went to two old houses that I wanted to hit for years. Only got aluminum at 4 to 5 inches. Milk bottle caps.. All the modern coins were down at 5 inches, dimes up as high as four. Remember Forrest Gump, "Stupid is as stupid does?" My settings were Sensitivity 5, Threshold, E in Tesoro. Settings for ground balance, and not upped for hunting.. So, went out this AM and buried a clad dime at 5.5 inches, same settings.... Rubbing the coil on the ground ,I got a signal, not great, only marginal directly under the sweet spot. A LITTLE to either side, and no signal. Thought, this sucks...Set the threshold on max, and sensitivity as high as it would go without chatter, then a half hair back.. A whole new game, another, easy, 4 to 5 inches above ground and getting a signal.. Inch or so above the ground, the cone much bigger, signal much stronger.It was stupidity on my part...I was splitting and stacking wood prior to hunting. Tired No excuse, because I've done this before....There are times when I pack the Vaquero next to the Silver, I think it complains about having to put up with me. Anyway, before the rains come, a large lawn to mow, then I'll go out and turn the Vaquero loose on full power. I am going to put a sign on my collection bag, CSS !...Check settings Stupid !
