Question; being new to the hobby,less than 2 years,all them litature i have seen recommends holding bottom of coil 1 to 1 1/2" off ground. My question. Is distant to target measure from bottom of coil to target or from gound level to target? My GTAx 550 will air test on a dime approximate 5". Does this mean actual working depth is 5" or 4 to3 1/2" Any reply's would be greatly appreciated. Sorry for the long post.Good hunting to everyone
