I''m not a marine electronics geek, but I do have an integrated
Raymarine radar,
chartplotter,
autopilot system installed by the prior owner. I am also sorry to say that I cannot share my experience with the system until after my first upcoming season. It certainly was impressive during the sea trial. Although, most
Raymarine users I know at my marina seem very satisfied by their equipment.
However, I have been told by other sailboaters that some JVC models have a low amperage draw, which of course is good when sailing. Whether that equates to a weak signal and poor performance may not be the obvious conclusion. First hand users, step up to bat.
