I have owned the coinstrike for about a year now. I admit at times I have put it away and used one of several detectors that I own. I am really starting to like the machine , For instance at an old school this weekend I had the coinstrike and the explorer 11 out to check thouse iffy signals. I came across A signal with the coinstrike the pretty much locked own to 26 and 27 , I checked it with the minelab and it jumped around so m,uch that I would not have dug it . It was about eight inches down when I dug it and was a old wheat penny .
