New boat and new to the Lake. I need a combo fishfinder / gps for my 21’ boat and am considering the Lowrance and the Raymarine A65. It will be primarily used on the Lake.

What about Bizer vs Navionics? Which one will help me learn the Lake better?

Is the price difference worth it for the Raymarine?

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!
