F2 sniper 4" coil

[wizz737]

Hi folks, I'm looking to make a 4" sniper coil for my Fisher f2. does anyone have any specs on this coil such as wire size and uH of RX TX. thanks

Only info I know of on fisher coils.

I don't know if the coils are the same as the F series.

Thanks for reply Homefire, I saw these specs on the forum as well but not sure they would work. On Fisher's web site the only coils I see that are interchangeable are with the F4 which is basically the same detector only with manual ground balance and a few more display segments than the F2.

My 4" coil for F2 has 2.4mH imbentance and 7.8Ohm dc resistance.

The 4 inch coil is about as cheap as you can get, why build?
Coils that work with the F2 are: BH 4 inch concentric, Standard BH 8 inch concentric, BH 10 inch (Magnum) concentric and the F4's 11 x 7 DD.
If your F2 is a newer one, with the metal-bodied screw-on plug/socket, then BH branded coils will not fit directly, you would need to change plugs. Earlier F2/F4's had the BH 5-pin 240 degree DIN connector, so they were all interchangeable.

Geo, thank you for reply. That's the info I'm looking for thanks for help. How do you like your F2 ? I just bought mine a few months ago and find it's excellent detector for the money.

skippy, thank you for reply. You are 100% correct the 4" sniper coil is only around $40 to buy so why I'm I looking to build one ? just for the fun in doing so I guess lol. My F2 is a new model with the new style connector as you pointed out. Good to know I can use the BH coils by just changing the connector.
