Their customer service ranks right up with Cabelas, Thats the best compliment I can think of. I bought two digitrolls on ebay and you would think I bought them brand new, personaly from the ceo of computroll. They have faxed me schematics and manuals. I called them and talked to one of their techs for about 20 min. about the home made "black Boxes" that were attached, giving me voltages and helping me track down what this guy had done. He took the time to lead me through a complete checkout of both riggers. About a week later I got a small box in the mail and he had sent me some minor wear parts (clutch washers) that I really did not need yet...FREE...NO CHARGE!!! And I did not ask for them...just a parts list so I could order parts when the time came!
Awesome company!!!

I have 2 Cannons. My UniTroll I bought from ebay, I noticed the counter was not counting correctly. I used a 300' tape to measure at 100' the counter would read 84'. I have a friend with UniTrolls who lent me one to use for an example as I rebuilt this unit. Surprise, his also read 84' at 100'. I emailed Computrol about this and a tech emailed me back stating they have never heard this complaint. I told him I thought the gearing was probably at fault, because the new spool I ordered came with a different gear that the original had. He asked if I would like a new counter. I said sure. Two days later I receive an express package containing a new counter and a couple of gear sets to try. Needless to say with the gear on the new spool, one of the ones he sent fit and now at 100' I read almost 99'. Close enough for gov. work! Oh, and the invoice for the new counter and gears and shipping stated NO CHARGE!! How can you beat that????
