I accept gratuities in the form of waypoints, jig poles, jigs and small denomination US currencies.
Just saying is all. :)
You're gonna love that unit. Might start thinking about where you're gonna mount the GPS puck. Front, Back or Console. I have mine at the back, but sometimes wonder if I shouldn't have put it on the bow. ????
On the Raymarine and Sitex..........I dunno. They look to be good units, but I think they are marketed to salt water guys and are very popular in the coastal areas. The lack of discussion about them is probably due to not many using them in fresh water and no one having any experience with them in that environment. Probably most of the tranducers that are prepackaged are designed for very deep salt water. Performance in fresh/shallow would probably suffer for it, but I'm sure they make a ducer designed for fresh and I'm guessing they would be very good, but would hate to drop that kind of $ for an experiment.
