Haven't seen a lot of Pan comments here, not a real heavy Garmin base here (yet/or whenever). Try some of the guys on BBC, Garmin forum. Ring Fry, Todd Driscoll, MonteSS, Larry and Leonard are but a few that come to mind. They are really good, helpful fellas. I want one to go on my 93sv and one day soon (I hope). Has to be awesome on schooling fishes. I think I want the forward pointing ps21. Will talk with Brian when time comes.
