CrappieStalker and I were discussing that very issue the other night. Mine seemed fine during the early part of the day and seemed to go hay wire in the afternoon. His seemed to be screwie all day. Glad you brought it up because I feel like there may be a problem with the unit. Don't get me wrong I like the unit but it needs some tweeking. The sonar portion is the bomb, I like the detail. May just ahve to play with it a little more to get here broke in...who knows.
