Contact Information

Can anyone give me the contact information for sending in the F75 for the Upgrade and service work?

I have written to the email address on Fisher site a few times now and no reply. Tried goggling First Texas detectors and couldn't find any factory info there either. You appreciate some info on who to write or call.

Tink, call Fisher at 1-800-444-5994 and ask for Felix. He will give you the lowdown and a Return Authorization (RA) number and other instructions on sending the unit in. My machine is in the shop right now having the work done and Felix was nice enough to call me about the battery springs...in my letter, I was asking for the spring "upgrade" where he explained to me that is some type of padding to make the batteries contact better. He just wanted to clarify that, which I thought was nice. Ron

Thanks Ron, I plan on sending it in and having the upgrade done and coil looked at. I have the new 4x6 and it really tear up the parks around me, but the larger coil really acts up a lot. I just got a new Excal and plan on going to the beach with it while the F75 is in the shop. Then its hammering some of these old farms and parts in the area with the F75.

Felix asked me to send the coil with the machine, which I thought was strange as they are working on the top end. Maybe they had a few bad coils and are checking them while the other work is being done. I don't know how mine is, I haven't even had it out yet! Four feet of snow yet to melt so I don't mind the machine being tied up. I planned on getting the smaller coil in the spring, do you think it's worth it? I hunt a lot of cellar holes and farm fields.

I have only had mine out twice since I got it a month or so ago. But I took it out to a small park along the river that runs into the ocean a mile down stream. So the water is really salty at times and salty sand is the soil base. I started out with the small coil and before the wife got out of the U shaped drive I had a dime at 2". I dug up 2 zinc after that and a few P-tabs. The next coin I got was a solid hit at about 3-4" down and it was corroded wheatie. So I find there is probably silver there. Only had 45 minutes to check it out.

I did put the large coil on before I left to see what would happen. There was just to many peices of trash for it to be effective. Even thou this large coil does a great job of seperating targets inches from each other, the small coil ruled in this situation.

I am not sure of the depth of the smaller coil yet. I did get really nice solid hits at 3-4" at only 35 sens. I also put the machine in All Metal No Motion for a while to try that setting out with the smallie. Personally I think that setting is the deepest and I have no problems using it over the Discrimination mode. I know lots don't like it but I had really good luck last summer with it pulling out really deep coins.

Isn't the most solid on IDing but when I got a solid higher tone signal I dug. It was amazing how many coins I dug for what might seem to others as trash with bouncing numbers and tones. The stuff on top seem to ID pretty good but these deeper 7-8" coins bounced a lot. maybe thats why they were missed by others. Most of them also seem to be in the 1960s era also. So they were down there for a while.

I got my small coil for Christmas and on trashy sites I now use it almost exclusively and have a good deal of time in with it. I've dug several coins in the 6-8" depth range and 1 silver dime at a true 9." I was in de process with 3h tones and the signal was a high tone tic and was a bouncy ID, but repeatable, so I dug it. The ground was moist and I was running with 80 sen. It gives nice solid hits down to 6-7" and id's good down to about 5", then the id starts to become bouncy. I recently dug a sterling silver broach about the size of a silver dollar that was about 4- 5" away from a metal fence post. No doubt, the broach had been missed by those with larger coils, including yours truly. For extreme trash site hunting, it is a good addition to have in mho. HH jim tn

Jim, would have been interesting to see what your machine and the small coil would have done in No Motion mode. I know most say they don't like it becuase of bounding IDs and single tone, but I get more solid ID on iron numbers then in Discrimination mode.

I found a kennedy half last summer down over a true 9". The signal was pretty good in Disc but when I switched over to No Motion not only was the signal stronger but it IDed it as a half dollar. Both me and SteveM were stunned at the depth and the strong signal from the F75. I have done the same with the small coil and iron and foil definately come in strong and clear down to about 5-6". Its when I get an iffy or bouncing signal I get excited and have pulled my best finds.

 

[jim tn]

Tink, I've now dug 4 halves with my F75, 3 Walkers and a Franklin, and the 3 Walkers id'ed exactly as a half. The Franklin did give a kind of jumpy id, but it was in a clump of dirt that also contained a Peace dollar and a rusty nail, which, would account for the bouncy id. None, though, were as deep as 9", all were 3-6" in depth. Ya, I like those iff, bouncy signals, too. I recently dug a 1943 Australia penny (they are about the size of a half dollar) bounced around as high silver. I have not checked yet as to its composition, but its not silver, by any means. I have had pretty good success in the de mode and while I do try some other setups, I seem to end up back in de most of the time. HH jim tn

I switch back and forth also. I really like hunting sports fields, especially football fields when I can get on. Founds some of my best jewelry finds on them. They don't seem to be a strashy as other places. Thats when I really like running the no motion. Deep, fast and tends to appeal to my hearing better. If not the No Motion it DE, 3H, 50 sens. 6 discrim or I notch out up to pulltabs.

It heading for the 60s this weekend and I found an old 1911 army parade field turned into a public park in the last 2 years. I am hoping for some silver, IHs and copper. Maybe some old metal or relics are still there also. Witht he strips of grass 4-6" wide growing along the cobble stone paths the small coil should be the ticket.

The small coil works and goes deep its a good choice..

 

[jim tn]

That old parade field sounds interesting. Good luck for some goodies. I like sports fields, too. Of the usual sites, they do seem to be about the best for jewelry. I've not had a gold now for a while and since I hunt just about everyday, I hope I am about do. Ya, I agree that the small coil is a good choice for the parade field. Let us know your results. HH jim tn

LOL. Now, I'd have given the Peace Dollar top billing and said I also found a Franklin.

I gotta get me one of them small coils. No doubt about it. I suppose it's too much to hope that if I wait they'll bring out an 8" Double-D.
