Summary: it is good for the money but it does not work well under trees. i went out geocaching in the woods and when i found the geocache it was about 30 feet away from the aproxomite spot the gps told me!
Summary: I purchased 9 of these for my high school students to use for an intro geocaching/gps class. They are inexpensive, relatively easy to use with minimal instruction, and the battery life has been good. The accuracy may not be as good as some other units, but usually get us within 15 feet of the desired waypoint in our area. They do tend to jump around in heavier cover, like pine trees. For the money they have been great units for geocaching.
Summary: Basic. However, an enough function. "high sensitivity GPS chip." It is expect in the forests.It becomes a good guide in the mountain where the road is indistinct. The direction of the compass screen and the map screen changes round and round. It is inconvenient for trekking. It continues by eneloop for 17 hours or more. However, the power supply often does OFF once while moving. The connection with PC is RS232C. A special cable is necessary.
Summary: There is not Russian in the menu of device, the first impression following- more functions what I expected.Anymore I will be able to say after перепрошивки into the language.A thing in is many cases irreplaceable.
