CREX is the lightest GPS-GSM unit on the market.

• 30x20x14mm (LxWxH)
• Weight from 13g
• Solar for many years of operation.

The CREX series is the lightest GSM tracking equipment available.  Each unit is capable of logging more than 10,000 points.  Additional sensors record 3-axis acceleration, light intensity, activity, and temperature.  When the units are within range of telecommunications networks, data are automatically downloaded from units and sent to you via email, stored in the online control panel, or uploaded to your movebank.org account.  Units also can be reconfigured by users after deployment thorough the online control panel, to collect more or fewer data, or to activate optional sensors.
