Let me say that I do like all of this detectors. What I have been doing is I hunt house from the 40s and 50s. I hunt the yard with the equinox 600 or the safari with a 8 inch coil then go back over it with the f75. Most of the time I find coins that they miss. Finding coins from 8 to 9 inch with all of them. I think all are doing good but don't sale your fisher.
