Turn by turn directions for marine GPS? That’s a new one on me! I was talking to someone who asked us for exactly that just recently. That sounds pretty slick, but can’t say I have ever seen that before.  After all, on a river or a lake the maps are going to show you where there are obstacles and where it is safe, deep enough for the boat to navigate safely.  Nobody sticks to just one particular route unless they are navigating white water or other treacherous situations, working around shoals or sandbars or whatever.

Anyway, GPS chartplotters or GPS fishfinder combos are meant to show you the lay of the land, the obstacles and the channels which, if you actually use their aid, will help you to navigate safely and to find where those big fish actually live, but won’t give you a strict street map setup.  After all, in my book that is much of the magic of spending time on the water, the ability to wander freely and enjoy the ride.  Again, turn by turn directions?  Not really, but marine GPS will still certainly help you to find your way and bring you home again.
