SeaCharter 642C DF iGPS Fishfinder/GPS Chartplotter?

Hello,
I'm looking at a SeaCharter 642C sonar/plotter and it looks to be a great finder for the price. The peak to peak power is 4000, which looks pretty good.

The only thing that may be questionable is the cone angles of the dual frequency 50/200 transducer, since I fish shallower lakes other than Meade and Powell once in a while. They are 35 and 12 degree angles. Does anyone see any major problems with these angles?

Update: Eagle emailed me back and said that this unit won't work for shallower waters. It seemed like a hell of deal for $409
