Question ? how do ya pinpoint those faint signals.. I got lucky yesterday.. I still haven't figured out how lol...on the quarter I got no sound or readings on VDI only a faint hit so I cut a about a 3 inch plug and then I pinpointed . Got a nice signal then. Am I on the right track? Anyone got any tips.. hate to admit it, but sometimes my holes turn into archaeological dig sites lolol.. Hey I always always fill em in lol
