Have about 250 hours on the F75 now and over 6400 hours on the Explorer ... LOVE EM BOTH
and I hunt with BOTH, and each has it's strengths and weaknesses.
You will love the feel of the F75, great battery life, cool back-light and it's fast hunt speed, no doubt about it ,but what these folks don't discuss about their F75 is that it actually sees so much more metal in the ground that YOU WILL HAVE TO SLOW DOWN with it anyway to get a good reading most of the time. Places like trashy old home sites where there is a lot iron mixed in with the goodies (targets everywhere) .... you might as well hunt those site first with the Explorer. Low and sloooooow gets the job done right the FIRST time anyway !!!
Wide open fields and such, especially plowed fields ... the F75 will eat the Explorer alive on ground coverage and hunts every bit as deep too.
Separation quality in heavy target areas is very good with the stock coil on the F75 and AMAZING with the small one, again with exceptional depth ... but I still find more silver with the Explorer and a 8" coil than I do the F75 on these kind of sites, maybe that's just how the odds have went so far, but it is what it is ... the Explorer is still the Silver King where I hunt and never gets dusty from closet visits
Yeah ... keep em both and you'll have the best of both worlds.
