Re: Handheld GPS differences
I've used the 78SC as my main chartplotter for a year, using a car suction mount. It works very well but as others have already mentioned in this thread, the small screen on handhelds means you are constantly zooming in and out. Zoom in to see small details like buoys, out again to see where you are.
Then I replaced it with a 5" chartplotter. I'm afraid that this was a huge improvement.
I still keep the 78SC as a backup.
I think you should check out Ram mounts, and I'm confident you could find a way to mount a 5" plotter - some mount it in the salon, so it hinges out into the companionway for use.
I used a Ram mount to mount mine above and aft of the compass.
