If theres a Target in the ground thats Good and your willing to dig the junk to get it out of the way so you can better pinpoint the good target, the F75 will Find it.It seems I always grab it over my other detectors.The separation and speed with the Larger Fisher DD coil is something to try for yourself.I would like to see a six inch DD coil for the F75 and a concentric coil also.
