I was in the woods with the Vaquero and stock coil . In an area with lots of trash . I got tired of digging trash and was on the way out so I cranked the disc way up . Beside a tree I got the best signal of the day , this was probably going to be a coin . But , there was a large root in the way and it was in the middle of a impenetrable root cluster . I used the saw blade on my Swiss Army Knife and went to work on the smaller roots but still couldnt get to it . I worked at it for maybe twenty minutes and was about to give up . I turned the sens down to 1 and the disc all the way up and there was still a super signal , I had to get it . I was thinking silver maybe even a quarter .There is a hatchet in my truck , so walked the two hundred yards , retrieved it , returned and went to work . This was one tough root. I chopped through it and there were feeder roots under it . So I chopped them out and finally was able to pry the root away . Inserting the pinpointer I get a the signal .Dug it out and it was a stinkin memorial Lincoln . I bet I spent a good 45 minutes on this thing . Oh well .
