UPDATED SPOT TRACKER
The new SPOT Gen3 has been out now for a few months with new features including custom tracking intervals, motion-activated tracking and more power options. GPS tracking is now switched on when you start moving and the integrated vibration sensor stops sending GPS data points when you stop moving. There are two tracking modes with variable data point intervals from 2.5 minutes up to 60 minutes. Along with 2 times greater battery life, additional power options include the ability to run the device via a 5 volt USB connection.
