Summary: I bought this to go hunting in unfamiliar woods. I tested in in several areas, and it is an amazing tool for finding your way through your hunting area or back to your truck after trekking through the woods.
Summary: I purchased this device for 2 purposes: (1) as a navigational aid when accompanying family and friends on hunting or other outdoor outings and (2) tracking and sharing my regular hiking and bicycling expeditions. As a navigational aid the system is slow but reliable. In the clear it can take 2 to 3 min to get a GPS lock, under a canopy it can take 2 to 3 times that long.
Summary: Does what we need it to do to meet the requirements of our State logs. They are not however "very rugged". We have had to replace 4-6 out of the 10 we bought originally due to the LCD screen going "black" or getting bumped or dropped by accident and the screen cracking rendering them useless.
Summary: This GPS does exactly what I wanted - tracks altitude, distance and temperature, and after the fact maps out where you went. However, it requires a standard USB input, so I bought a Surface RT since iPad and Kindle don't offer USB. Unfortunately it ALSO requires Adobe Air which is not supported on Surface RT. So I have not been able to find an easy travel solution to be able to do what I want with this. Disappointing.
Summary: It is a basic unit, but it seems to get the job done. Have not tested it in the woods yet, only around my neighborhood and park. This upcoming hunting season will determine if it is worth anything.
Summary: Bought the unit for a trip overseas to mark locations of cars, hotels, etc. At times, it took 10-20 minutes to locate a satellite (even in wide open areas, with clear skies), Compass was useless, and constantly pointed in wrong directions. Retrace function, in which the arrow points you to a user-determined set of coordinates was wrong 90% of the time, and in one instance, led us (1) mile in the wrong direction.
