Houghy,
There has to be a good reason why someone who owns a Kendrick Digifire 7 told you he wouldn't have another one. That would be me. There has to be an even better reason why someone who fitted the Kendrick Digifires to every scope he sold (Peter Read at SDM), changed over and now fits the Thousand Oaks system to all his scopes.
I have to ask why you even bothered posting the question because none of the advice you were given sent you in that direction.
You could have had my Kendrick Digifire 7 very very cheap
Every time you do a slew and the servo motors on the Servocat Drive kicks in, the low voltage cutout on the Kendrick Digifire 7 also kicks in
It's a piece of crapola from my point of view. Probably the same reason Peter Read doesn't use them anymore either.
Cheers,
John B
