New SPOT Gen3 Features
Choose your Track Rate: New upgraded tracking options, Unlimited and Extreme Tracking, allow you to choose the rate at which your tracking messages are sent – every 2 ½ , 5, 10, 30 or 60 minutes.
Extended Tracking Mode: Adventure doesn’t have a time limit and neither should your tracking. When you upgrade to Unlimited or Extreme tracking SPOT Gen3 will continue sending tracks for as long as you keep moving or until the power runs out.
Motion-Activated Tracking: No matter the tracking service level you choose, SPOT Gen3’s tracking has the added benefit of being Motion Activated. A vibration sensor tells SPOT to send tracks when you are moving and to stop when you do. This conserves battery power and keeps your Shared Page from getting cluttered when you stop to camp for the night.
Longer Battery Life: SPOT Gen3 has nearly twice the battery life of the SPOT Satellite GPS Messenger! Keep the adventure going even longer, without the hassle of changing your batteries.
New Power Options: Now there are more options for how you power your SPOT! In addition to using the included 4 AAA Energizer® Ultimate Lithium 8x batteries, you can use NiMH rechargeable batteries or, line power your SPOT Gen3 with a 5v USB connection.
