I glanced at the manual some when the unit came in and printed it off. But the truth is that I have not needed it at all. It is still sitting in the compartment I put it in the day I took the 998c out for the 1st time. I was really impressed but the ease of use, and how quickly i was doing cool stuff. like making SI and DI adjustments.
I was also impressed with how quick the LakeMaster was to pick up.
I paid a lot of $ for this unit and it has exceeded my expectations to this point.
