I'm doing the same thing you are, in the process of setting up a complete system of electronics
. I have toyed around with all of the brands, and I have decided to go with B&G. I really liked Raymarine's chartplotters, and Garmin
has a nice, easy interface as well. B&G makes some sailing specific software
that includes tacking lines, etc., however Garmin and other brands are starting to implement these as well.
When it comes to radar
, Simrad/B&G/Lowrance makes a broadband
radar (3G or 4G), that is a little different than traditional radar. Something to consider.
