<HTML>Hi. I might be able to help. I really don't have the info on the coleman 11, but I do have a SAT II if you can give me the info to feed it. I didn't use the Accutuner for my test. I took the test aurally, but do like to use the accutuner for the help it can give me. I've been tuning for 11 years, now. Not sure how much I fit the bill, but if you want someone with more experience you would have to go out of the PTG or check in Tampa/Clearwater. Regards, Ron Pruitt RPT</HTML>
