Hey Jackpine I checked my model number on the 1270

[Keith Southern]

and its got a c at the end of it .I told you it didnt have the modification done by looking for the extra resistors soldered in so i called fisher and talked to Daniel he said the C models have it incorporated into the board just the A and B needed to be externally modified.Actually there up to the letter F he said.

I know this is a sweet running machine with excellent depth and sensitivity. Its hotter on P-Caps than ---- well I better not say . Even runs fine in some of this iron oxide dirt I have and actually hits on targets in disc other machines with manual ground balance have problems with..

Any how thanks for the info you provided in an earlier post .Heres a shot of the C model with the iron mod incorporated into the circuitry.

It's good to hear that Fisher did not stop with just adding the mod and continued developing it with the new board. Thanks for the Info. Yours sounds like a keeper! I'm gonna have to put a new one on my want list now!

PS: Have you checked at 0 disc in either the normal or iron disc mode to see how it responds to your ground when bobbing? Mine "was" very negative, it gave a big Waah sound on the up stroke in disc.
