F2 - F4 coil

[Coinfishing]

Does anyone know if Fisher F2-F4 coils will work on the F5?

Nope, they won't.

Ok, just curious- but is it that they won't work at all, or they won't work to optimum performance?

Is there something different about the winding? Maybe the winding from the F2/F4 coils are not quite as "hot" as the F5 coils? So... The electronics would be calibrated differently for each?!?! I don't know?!?! Lol

Just wondering because I have a 5, and I got an F2 for the wife to swing- the 2 coil package from Kellyco, and I've noticed the plugs are the same! I keep eyeing her sniper coil which she has yet to touch! I could put that thing to use on the 5! Hahaha

Electrically they're very different. The F2 coil won't harm the F5, it will probably beep, but won't work worth a darn.

Ok, did some experimentation and you are right sir!

The 8" concentric that comes stock on the F2 will function on the F5 BUT- it yields less depth than when it's on the F2 on an air test! It picked up a dollar coin at like 4.5- 5 inches?!?! Terrible! Lol and the TID was all over the place though repeatable haha!

I tried the 4" coil as well it was a little more stable on the F5 but still didn't read as far out on the air test as it did on the F2.

Since I was doing all this swapping around with coils, I went ahead and threw the 11"DD from the F5 on the F2- BY FAR THE WORST IDEA EVER! Very unstable even at the lowest sensitivity setting! I got what seemed to be a few hits on that same solar coin but it had to be right on the coil, and again TID was a complete mess!

It was educational and interesting though, I think I wanna find out more about the way these things work on the electrical/electronic level. I have an idea, roughly, but now I'm deff thirsty for knowledge on this. Thanks Dave, you called man- I wasn't really surprised though after you said that though.... I'm sure you weren't either lol.
