The GPS is a easy to use and a perfect tool for use on the water. I have not yet purchased a map so I am really interested to see how that will work. Great product so far!
This is a nice little handheld unit....screen is kind of small which is a con in that its small but a pro in that it makes it very much lighter....... unit is like having a navigational marine wizard at your side.....
This replaces my old GPSMAP 76 which still is a fine machine. The GPSMAP 78S has a more sensitive receiver (it got a cold start fix in 30 seconds in my living room), the menus are intuitive (easy to use) and the color display is easy to see in full sunlight (no back light) and in subdued light with the back light switched on. The built-in compass 3 axis calibration took less than a minute and is easily repeated for each new environment (on board ship, in the car, or in the woods). In short the GPSMAP 78S fulfills my high expectations for quality from Garmin.
I was using previously one of the older model of this type with black and white screen. When looking for another unit years later it was really easy to make up my mind. Decided to take this as versatile device that would be good both on water and on hike in bad weather. Battery life is great and with my usage patterns they last really long time - three fishing/hiking weekends easy. Unit has great functionality and everything I need is packed there. However as the years go by - one may wish for a bit better display, but that is mostly due to my poor eyesight. I would recommend this unit regardless of the fact that smartphones these days offer perhaps better mapping services, but thy are not reliable while you are away from socket for days and in more challenging conditions.
