Garmin GPSMAP 78SC Marine GPS Navigator
Whether you are in a kayak or motor yacht you will always know where you are with the Garmin GPSMAP 78sc. This handheld navigation device comes preloaded with BlueChart g2 coastal charts, which include shorelines, depth contours, navigational aids, harbors, and marinas for the U.S. and the Bahamas. It is equipped with rubber side grips that encourage a firm hold even when wet and features an IPX7 waterproof construction that floats in water. A 3-axis compass is built-in so you will always know your heading. An altimeter lets you know how far you are above sea level, and can help predict weather trends. The unit runs off two AA batteries which are not included.
This unit utilizes both GPS and GLONASS satellites for quicker signal acquisition so you get a fix on your position approximately 20 times faster than GPS alone. A worldwide base map is stored on the unit's internal memory so you will always have an idea of where you are.
