Well, as I related back at http://www.treasurenet.com/forums/fisher-research-labs/436265-fisher-f75-strikes-gold-twice-row.html I have been a long time fan of the Fisher F75 but like many people I finally let it go because it was not playing well with electrical interference in urban areas. Most of my use had been in remote locations but I wanted to weed my detector collection down, and I decided a detector I could only use out of town had to be cut. As the post in the link goes on to tell, I was really excited when I got to try a prototype F75 out. It seemed to solve my issues plus add a couple new tricks to the mix.
I finally got a new production F75 Ltd2 recently (12-14 version) and was anxious to try it out on an area where I had found a few older coins previously. The problem is the ground is sandy and loaded with magnetite, running 5-6 bars on the Fe3O4 meter. I had run several other models of detectors here with stock coils and was getting no depth at all. Heavy magnetite really shuts down stock coils, and it did not help that there was a lot of nails, wire, and other ferrous stuff in the mix. So I hit the location with the F75 and 5" DD coil and it was like the place had never seen a detector before.
Anyway, I dug quite the pile of coins and there are plenty left to go find. I cleaned out the pouch and had 14 wheaties, mostly from the 40s and 50s, a 47 and 51 dime, and a 59 quarter plus a small pile of clad and some zincolns. Some kind of ring (too light for silver, to heavy for aluminum), a little silver heart/cross pendant. and a neat little Caldwell Bus Co token with the hole in the middle. Anyway, nothing exciting, I was mainly just really happy to be running the F75 maxed out in a park in town with no EMI issues at all. Not a whisper. I was running DE at 99, 0 disc 3H getting coins down to around 5 - 6 inches, which is superb in this kind of dirt. I would say about 50% more depth than I was seeing with other top brand units running stock coils. Great machines, just too much coil for the dirt. I am sure the F75 would suffer also if I had the stock coil on it. The larger coils will often see the coins but usually identify them as ferrous targets.
Anyway, just pleased as can be with the F75. I have been selling off a lot of my extra detectors but this one is a keeper.
