First off,..you'll wonder why you didn't get one 5 years ago.....they are awesome!! Secondly,..remember,....when you go from point A to point B via GPS it is a straight line UNLESS you plot a course. If there's an island or obstruction between point A and B, you will hit it or come dangerously close to it on your way to it. You need to keep that in mind when traveling at night. Learn how to plot a course on your GPS, around such objects at night and you'll get home safely and without incident.
You'll love it....they are the best things you could have on a boat for navigation.:wub:
