Hi Bobby,
Do I recommend the F75 for what? Gold detecting?
I hate to tell you this Bobby, but the F75 is just another darn metal detector. It obviously is working well for quite a few people as regards the posts on the F75 forum.
I have my own interests which basically involve gold. I gave the F75 a brief spin to see if it had something that would jump out and grab me as a gold hunter.
The F75 in the all-metal mode has very good depth. It is reasonably good on small targets. And so I have no doubt you could go find gold with it. The F75 has an exceptionally fast response time. But other than that I saw nothing that would make me stop the presses as far as prospecting goes.
The F75 costs more than most dedicated VLF prospecting units and it has exactly one coil available for it. If VLF propecting is your interest than I'm guessing at this point that there are dedicated units available that cost less and have far better coil selections that will do as good or a better job looking for gold nuggets.
Maybe once I get time to run one in real goldfields I'll have more to say on the F75 as a prospecting unit. But I have to say it is low on my list of priorities. I am far more concerned with firing up my new GPX-4000 and getting some serious time in with it. I have no doubt it will blow the F75 away as a prospecting unit.
I see you making lots of posts asking people to compare units. I'm flattered that you value my opinion, but I'm not out to prove anything about detectors to anyone but myself. There has been but little real change in VLF performance since 1990. In my mind it is a combination of operator and location that wins the day, not nit-picking differences between VLF units that are all very much alike. What matters to me these days for casual detecting is that the machine feels good and sounds good and so for just having fun around town detecting I'm liking the X-Terra 70. That although many would argue it is no top-end powerhouse. Mind you I'm NOT saying the X-Terra 70 is "better" than the F75!
What do I care, as long as I'm having fun? My other fun unit for around town is a White's DFX with Bigfoot coil. I disc out pennies and dimes and dig the rest. It is great for hitting big fields although it has what most people would consider poor depth due to the Bigfoot. Sorry, I do not care about depth. I'm hunting jewelry and care more about covering area. In fact if I can't pop it with my screwdriver I usually pass it up.
When I want depth I rarely consider VLF units these days unless they are run in all-metal mode. And because of that I am more intersted in PI units than VLF for depth. Currently the Minelab SD/GP units set the standard there, although there are some potential options coming this year I want to get my hands on. So when you ask me about the F75 as a prospecting unit you do not really get my interest. I'm certain without even trying that my GPX-4000 with 21"x27" DD coil will hit a large nugget far deeper than the F75 can even dream about.
Just as I am certain my Gold Bug 2 will hit smaller gold than the F75.
So for this summer I will be using the GPX-4000 and Gold Bug 2 for prospecting. The F75 is not really on my list. For in town I'm happy with my X-Terra 70/DFX Bigfoot combo.
Maybe that helps you and maybe not. But ultimately nobody can tell you what detectors will work best for you Bobby. I can tell you what I'm liking but when I do that that is exactly what I am doing - telling you what I like. I'm not making any caims as to what will or not work for others. I can tell you one thing, and that is that looking for the perfect detector is pretty much a waste of time. All that really matters is getting some kind of decent unit and getting out and using it a lot.
