The new eTrex 10 retains the core functionality, rugged construction, affordability and long battery life that made eTrex the most dependable GPS device available. The new eTrex series is the first-ever consumer-grade receivers that can track both GPS and GLONASS satellites simultaneously.

The new eTrex series is the first-ever consumer-grade receivers that can track both GPS and GLONASS satellites simultaneously. GLONASS is a system developed by the Russian Federation that will be fully operational in 2012. When using GLONASS satellites, the time it takes for the receiver to “lock on” to a position is (on average) approximately 20 percent faster than using GPS. And when using both GPS and GLONASS, the receiver has the ability to lock on to 24 more satellites than using GPS alone.
