Hi All - Just got my F75

Hi,

Well, went and did it. I just got an F75 along with the small elliptical coil.

I have to admit I was put off of Fisher for awhile due to issues revolving around the decline of the old Fisher and the takeover by First Texas. I think it is obvious to anyone who watched that product quality suffered for some time. I went so far as to voice my concerns to the people at the new Fisher and I have to say to their credit they admitted there had been issues but they assured me they have been resolved. And reports of late have been far more encouraging. In particular, I have a huge amount of faith in Dave Johnson. He has had a hand in so many of what I consider the best units made for my purposes by several different manufacturers that I owe a great deal of my detecting success directly to him and units he has helped bring to market.

So I've decided it is time to get back on board with Fisher. The F75 has obvious potential as a prospecting unit and so that is what I'll focus on with the unit. I went and hit a tot lot last night. We have some quite magnetic pea gravel here that really puts a dent in VLF performance. The static all metal mode wowed me, especially the ability to still get target id information while in that mode. I'll be getting out to the goldfields soon and will report back on how the F75 does for me as a nugget machine. The little elliptical should be a killer on little nuggets and I am pretty certain the F75 will do better on large nuggets at depth than the Gold Bug 2. The GB2 can't be beat for sensitivity to small stuff, but its exceptionally high frequency means it does not penetrate for depth all that well. The F75 frequency and DD coil make it a probable better unit in some ground types and large gold than the GB2. Just some educated guessing on my part - I'll prove it one way or the other soon.

Steve i don't know if the 5in DD is to small for your hunting style .I have the small elliptical and my ground is on the
mild side so one over the other is not a big deal as the 4 x 6 is a little deeper and the 5inDD is better in trash.
I keep my fingers crossed for a tweener coil like a 5 x 10 ish Dont overdrive to start ,watch out for the notch in / out
If i figured it out it should be easy beans for you HH Mike
 
Hi Mike,

The 5" DD would suit me for hunting coins in trashy locations. For detecting tiny nuggets I'll stick with concentric coils. The 6" elliptical is the best nuggert coil Fisher ever built. If I could wish for a coil for the F75 it would be a 10" elliptical concentric - the same coil as comes stock on the Gold Bug 2.

I know lots of people like DD coils. Not me. Give me mono or concentric coils. DD is a pain when running hot. Like at the tot lot. Right off the bat I found out the F75 DD coil hits at the center and on the edges of the coil. Multiple hits per swing. And the VDI is off on the hits off the edges. So I had to use short little swings to focus the hits on the center DD strip to get accurate VDI numbers. Kind of annoying.

But that's just me. I tend to run detectors in ways they were not intended to be run. I expect the DD to possibly do well in the hot rocks however, so it's not like I'm complaining. But I would liketo try a larger concentric coil on the F75.

I"ve been hard on the F75, but I can tell you that the all metal modes are amazing. Even in discrim though, I've pulled out solid hitting earring backs and literal flecks of foil. I'm interested to hear how it does in wide open gold country. Let us know.
 
When do you figure to start getting camp ready.

Wish I could make up there.

Hi Tom,

The snow usually leaves the strip by the end of May. We will head out around Memorial Day, me for just an overnighter. A couple of my partners will stay and do most of the set-up and I'll go back in a week later, just before our first visitors show up.

I'll go to a local creek before then to give the F75 a spin on little gold nuggets. At Moore Creek I'll be more interested in how it handles the hot rocks.

Steve, Congrats.

Take a look at the manual again and swing speeds for VDI report.

If you recover some deep targets, perhaps you could comment some time on VLF vs. Pulse with the F75.

My opinion is the F75 nears the depth of pulse with repeatable tone response on some targets, using similar sized coils.

In no way will it have greater depth, but my observation is the gap between the two types of detectors with this machine is lessened.

Other VLF's mask or miss/false these same deep targets, when a.pulse reports.
Just MHO.

Have a great summer!

Didn't you get a new whites? I have read your posts and you don't feel compairing different detectors is a good way to judge which one is better. but I would really like to know what you think of both machines. My buddy wants to get a new machine and I said well if I were you I would get the F75 but if the whites can hold its own then maybe you should spend the extra money...He wants to go coin
shooting on turf and very little relic hunting... I think the F75 is a great coin shooter on turf and for old coins while reclic hunting.

Hi Elton,

It will never be hard for me to use other detectors. It is something I enjoy - using lots of detectors. Playing with the toys so to speak.

I generally use PI detectors these days. I've not seen much change in VLF detectors since about 1990. I was as happy with my CZ-5 as with anything I've used since.

Steve Herschbach
 
and it will at "least" be one of your favorites.. It a very good all around detector with serious depth in my ground.. I hope it works the same up in your land...

I know you use many detectors and are very good with them..enjoy your new F75.
 
Hi Low-Boy,

Yup, got the V3 and then picked up the F75.

You know, it is different strokes for different folks. My uses are extremely specific. The V3 I will use pretty much exclusively with my Bigfoot coil to sweep sportfields for jewelry. It is as much about the Bigfoot as the detector itself. I may do a little coin detecting with it but that is pretty much last on my list of detecting interests these days.

The F75 I'm primarily interested in for prospecting. Maybe some all metal tot-lot use. I do a lot of "beep-dig" detecting. The static all metal mode is quite impressive. But I doubt I'll be doing much coin detecting with the F75.

I live in Anchorage, Alaska. The town was founded in 1915. There simply is not much in the way of old coins to be found here and the oldest portion of town is paved over. 1930's are about as good as it gets. 1920's would be a superb find. The ground here is not deep, so most places are basically hunted out. I'd really be into turf hunting if I lived someplace where 1800 coins could be found. But that is not the case here, and so coin detecting, although I enjoy it, is just not that important to me. In fact I often consider coins to be trash targets. When I am chasing jewelry I like notching out everything from zinc penny on up to just below quarters. Which by the way can't be done with the F75, much to my surprise. Why limit the notch capability?

Anyway, that is why I tend to bow out of the turf wars. It is not my area of interest. The only thing that perked up my coin hunting interest was when I started using PI units to pull up old coins no VLF can touch. That was fun and I'll no doubt go do it again.

Steve - I used the F75 at Greenhorn Creek in 07 and am pleased with it. Hot rocks can be a problem. You may be able to balance them out if sensitivity is lowered to 50 or so and still get decent depth on larger nuggets. But if high mineralization, I recall, need to dig most signals as discrimination, even for high conductors, seems to read 14. Also you may need to re balance separately over individual hot rocks. But for lower mineralization the depth is one of the best for a VLF. I seem to remember a post that an F75 was used at Moore Creek without finding any nuggets. But I feel that could have resulted from not knowing the capacities and the limitations. Its light weight makes up for the limitations though may limit where I can use it. I much look forward to hearing of your experience at Moore Creek - one way or the other. I probably will not make it to Alaska this summer unless the market keeps going up. It is time for me to go practice on my hot rock pile. Lance T. in Santa Rosa, CA
 
Hi,

There was a F75 at Moore Creek at one point but the real story is it basically did not get used enough to prove much of anything. But I saw enough to think it will do pretty well - for a VLF.

Thanks for the feedback!
