Fisher F4 Frustration

Have you talked to Fisher about this problem?
A phone call is free...ask for Felix if you call because not all the reps there are as well versed and logical as he is....some of them have been known to tell people some strange things.

My F2 could be chatty sometimes, lots of times but I always hunted with the sense turned all the way up.
Still it was never super bad, didn't happen all the time and if I turned the gain down it always got quiet.

Could be something going on at that one beach, have you hunted in other areas, other beaches or parks with the same problem to make sure it isn't the detector?
A 5 year warranty on this thing if you bought it new, hopefully you didn't wait too long and this is an issue that can be fixed if it is the machine and Fisher says they can fix it.

Try this also...it seemed to have worked on and corrected several wonky acting F2's over the years for a lot of us even though it is not supposed to do anything and according to the factory there is no factory reset on these models at all.
We don't care, we did it anyway and most of us were glad we did.

Hit the power button and leave your finger on the button pressed down for about 10 seconds after it powers up.
You won't see anything on the screen or hear any thing different and don't ask me why this sometimes works...it just does.

Cell phone?

Are you hunting dry or wet sand? Every beach I got to in CA VLF goes nuts in wet sand.

If it's dry sand and you still have a problem, one call, thats all

GL~!

Just noticed you said dry. Probably a detector issue.

I had a f4 and it was real sensitive to emi. It would just go crazy like a machine gun. That being said I don't think that would be a issue with your coil unplugged. Sounds to me like it's time to send it in.

I've been on some beaches that are just iron rich, pita noisy. Black sand and lots of iron trash like square nails galore. Black sand can be a problem! And also sometimes the dry sand has salt wet sand under it, depending on how close to the water you are. Good luck.

I have a f4 and have had that problem a handful of times. no beaches near in WI!!! I took out the batteries for a few minutes, it seemed to work for me. I will try holding the power button as someone suggested if it happens again.

Had a similar problem a few years back , sent it in to be checked out it had a defective circit baord and a defective coil , they replaced both ,with no problems since.
