I would have thought if it were a danger, FTP wouldn't have made the plugs the same (or the way the pins line up). On another forum, Dave J (FTP engineer) said that they (6.6) work on the Pro line, but not as good as the 7.69 coils do.
Here's what another member said about the 4":
The actual definition of "works" can be interpreted in a few ways.
I have 3 of the 4" push in coils. None will work properly on my Land Ranger Pro. I have direct word from a person who works at First Texas that they do not have a 4" coil that is compatible.
Not working properly and not working at all are 2 different things. These coils will make the proper sounds and indicate the correct numbers, but will only get about 2.5 inches of depth.
And Dave J said this about the different freqs:
Don't worry about the frequency thing, that's stone age urban mythology.
I'm not vouching for the aftermarket coil (we didn't make it) but just trying to dispel the frequency myth. The "Greek/Fratbros" series DD searchcoils are what's used on the 19 kHz GB/G2/F19 machines, and we're also using them at 3 kHz on some engineering lab projects..
