What are you using? or what do you wish you had and why?
Trying to decide between using a handheld GPS or installing something.
Boat will be used in BVI so its more of a need & handy gadget then a necessity.
What size boat, what is yor budget?
I think the best value is with units that are preloaded with charts at least in the US. If you are leaning toward handhelds, Garmin by far has the largest selection.
