F75 & iron

[ky digger]

Over the last 15 years I've tried half a dozen Fisher machines. And before I go on this is an attempt at a legitimate question not just a sarcastic statement.
The primary reason I tried to force feed myself a Fisher was because I could hip mount or chest mount most of them and I have a problem with rotator cuffs. The problem is iron. Every Fisher I've tried just loves iron. I search inland in Kentucky and surrounding areas for the most part. No beaches, and no sand. I dig so many false iron signals with any Fisher it ruins the experience. I've used the DFX and all the White predecessors, and have used the Explorer II for the past 3 years with a bungie harness to remove the weight. The harness solves the weight problem, and the detector get the deeper stuff with a minimum of false signals. Very little iron. It has drawbacks however such as target pinpoint, depth id, etc. Not so accurate, but deep, and accurate enough.
I can't help but be curious after reading the posts here about the F75. If there is anyone out there that can compare previous Fisher machines with the F75 -ONLY WITH REGARD TO IRON DESCRIMINATION? FAct is, if the F75 doesn't pick up iron bits like all previous Fishers I would love to try one out, but experience is the best teacher, and here in KY FIsher loves iron.
One last thing. I got the video from the rocket scientist that digs dime targets at 13 inches. Only in sandy soil will that be accomplished. Bring that thing here to KY and you will have to wait for the next 120 years to dig a dime at 13 inches. Not going to happen here. If the F75 can get a coin in Kentucky at measured 9 inches it will equal any other machine made.
I would really appreciate you Fisher guys reading my comments in the objective spirit in which they are intended. No bashing here, just real questions based on real experience.

I don't live in Kentucky nor did i use the old style Fisher detectors much.
I'm a Fisher user since the F75.

You best bet is to meet with with a guy who has a F75 and try it over your soil. Due the the ground canceling DD coil of the F75 there is a good chance that the F75 could work well in your soil.
Iron seems not to be a problem with the F75. I haven't had any iron problems and on the forums you don't see people posting about iron problems with the F75.
It is more the other way around, you see F75 user posting finds out of iron infested sides that have been hunted with many other brand detectors.

Hope that helps and i hope that someone from Kentucky can answer too.

Digger, I live in East Tennessee and assume that the soil is pretty comparable to that found in your area (hard packed red clay after a few inches of clay mixed with topsoil). I do not have a lot of experience with the older Fishers personally but I have watched others pull their fair share of iron with them.
I have posted before that my yard was literally a scrap metal storage yard before I moved in here. There is more aluminum, copper and iron in the ground in my front yard than I ever imagined possible ranging from 1" to 10" or so.
I have owned the F75 for close to a month now and have put many hours on it both in the yard and at several older home sites and parks. I have not dug a single piece of iron that I did not think was iron before digging. Is it infallible? I can't say, but I am impressed.
The target ID seems as accurate as anything else I have used (White's analog and digital and Explorer II and SE which I still own as well.)
Pinpointing is spot on after a little acclimation.
Target separation is faster than your mind can process sometimes. Lay a coin on top of clean ground and sweep it and you will hear three beeps. One from each outside edge and one from the center.
As you mentioned the soil in this area is a depth killer but I have recovered dimes in red clay fill at around the 8" mark with the F75.

I hope this helps.

Excellent information. Thanks much. Do you find that the F75 achieves comparable depth to the EXII?

 

[Neugene]

I think that depth is pretty comparable. The one thing that I think the Explorers have over the F75 is the ability to adjust the gain. Deep targets sound deep on the F75 which may or may not be a good thing depending on how good or bad your hearing is. Crank up the gain on the Explorer and deep targets sing out. However, too much gain can result in needing to lower your sensitivity to maintain stability. Kind of a delicate trade off/best compromise situation.

I have found that I dig more iron with iron discriminated out. If I use very little or no discrimination I can hear the low tone and the high tone that iron very often makes. It works pretty good with the F-75 and the CZs. As far as the F-75 goes, if you can, try one before you buy one. It seems that people either love them or hate them. The jury is still out on my end. I can say that it is nothing like a CZ.
