Stay connected wherever your adventure takes you. The SPOT Gen3 starts tracking when it sensors motion and uses satellite technology to trace your adventure and send messages. Sends pre-sets contacts or local rescue team messages or help alerts. Includes 3 motion-activated tracking levels - Basic, Unlimited or Extreme. Motion-activated tracking sensors vibration and send tracking updates when moving. When movement stops so does the tracking updates, saving battery life and preventing duplicate tracks. Continuous Tracking (only available for ultimate/extreme tracking levels) sends track messages until your SPOT Gen3 device is turned off. No need to reset after 24 hours. SPOT Gen3 features a new Unlimited tracking, allowing you to pre-set you SPOT Gen3 to send your tracks/route and the speed of your adventures in 2.5, 5, 10, 30 or 60 minute intervals - this will send tracks at your chosen rate for as long as is moving and turned on.
