The new GPSMAP 79 Series from Garmin puts all of the necessary navigation tools in the palm of your hand. Interacting with multiple constellations, they allow for accurate data gathering worldwide. With an impressive 8BG of data storage, they can hold up to 10,000 stored waypoints and 250 routes.
These upgraded models offer 2.5 times the resolution of their previous range, with better contrast and less fogging. With an internal battery that can last 19 hours, they can also float and are water resistant.
Not bad for about $300!
