Boating GPS Units & Chartplotters

Customer Reviews. Garmin GPSMAP 78S 010-00864-01 Marine GPS Navigator and World Wide Chartplotter This unit replaced my Magellan GPS 3000 which had replace an older Loran C unit. The older unit was not a Chartplotter and had great difficulty in acquiring satellites when on shore. The 78SC acquires satellites within seconds of turning it on as long as you are outdoors. Although it did a pretty good job acquiring them even indoors most of the time.

It is nice to have a Chart to give you a visual of the area you are in. I always was concerned that the older unit I had would guide me right into a breakwall in poor visual conditions, if I didn't have an old route map to rely on. The built in map is sufficient for my purposes as I only need to rely on it for fishing purposes on Lake Erie which is part of the coastal maps included. I seldom if ever need to rely on it for poor visual conditions and I am only guiding a 16' aluminum boat fishing fairly familiar areas. The general need is to be able to find structure for fishing and being able to mark spots where I have had previous success. It is good to be able to see where sandbars and old wrecks are located in an open lake. All its features function accurately and it wasn't too difficult to learn and use. After one trip out with it I am ready to trust it completely.
