Garmin Foretrex 601 - GPS watch - hiking 2"

Key Features and Benefits:

• Tougher than it needs to be
  Foretrex navigators are beyond durable. They're built to military standards for thermal, shock and water performance (MIL-STD-810G). They also include tactical features such as compatibility with night vision goggles and Jumpmaster mode.
• Multi-GNSS navigation includes Galileo
  Foretrex navigators work with 3 satellite navigation reception networks, including GPS, GLONASS and Galileo, to track your position in more challenging environments than GPS alone. Explore longer - battery life exceeds 48 hours in navigation mode and lasts up to 1 week in UltraTrac mode.
• Navigation sensors keep you on track
  To guide you on and off the beaten path, Foretrex navigators provide comprehensive navigation and tracking using GPS plus ABC (altimeter, barometer and compass) sensor capabilities. The built-in altimeter provides elevation data to accurately monitor ascent and descent, while the barometer can be used to predict weather changes by showing short-term trends in air pressure. The 3-axis electronic compass keeps your bearings, whether you're moving or not.
• Stay connected
  Smart notifications - available on both devices - let you receive emails, texts and alerts from your mobile device right on your wrist. Use the Garmin Connect Mobile app to initiate the LiveTrack feature to allow others to follow your journey (within cellular coverage). Other connected features include automatic uploads to Garmin Connect online fitness community and automatic software updates when paired to a mobile device.
