Both are really good i am so used to lowrance system operation that the switch to raymarine has me going goofy. It is a very good unit and you can't go wrong with either. I am planning on getting a Lowrance that costs more than the Raymarine A65. In my opinion the Raymarine fishfinder High Definition digital fish imaging gives a better picturethan anything else out there but i think the lowrance GPS / chartplotter is easier to use (at least for me) probably because i am used to it. The new Navionics paper chart of winni is AWESOME!
