This GPS device features a trans-reflective TFT screen for superb display. The pixel density is an amazing 160 by 240 pixels.
And the screen size is 1.6 by 2.2 inches. With all this technology packed into such a small screen, the clarity of pictures is assured, and the device has a screen that is visible in both foggy and clear weather.
The 78sc took the best of its more expensive touch screen cousins and made it its own on its non-touch screen. The screen might be non-touch, but it still works as well as the more illustrious cousins.
Menu navigation is easy due to the easy layout of the icons on the screen. Changing from the new ribbon menu navigation scheme to the old scheme is Easy and possible for the manufacturers knew that some people would still find this old navigation preferable
This device weighs very little, just over seven pounds to be exact. And this little weight is one of the reasons that make it floatable. There is, therefore, no fear of the device falling overboard.
There is also the man overboard button used to set a waypoint and signaling the boat user to begin navigating towards it. Compatibility with coastal charts is also possible and highly encouraged.
Advanced Compass Design
The tri-axial compass is an innovation in the design of the 78sc that makes sure you don’t have to hold the unit level while navigating. There’s a downside to this; recalibration is harder than the dual axis compass.
With time, however, and lots of getting used to the device recalibration becomes much easier. The user should, however, remember that any time batteries are changed the device has to be recalibrated.
The 78sc makes it possible to upload any map to the screen and use it. Any map that you want to use should be easily uploaded to the interface and made available for use.
Map programs that one subscribes to like the one which provides maps at a small fee- no more than $ 30. These maps make navigation in areas that are unknown easy.
