And unlike Personal Locator Beacons, SPOT does more than just call for help - tracking your progress, checking in with loved ones, and non-emergency assistance are also available - all at the push of a button. And because it uses 100% satellite technology, SPOT works around the world – even where cell phones don't.

Check-in feature - you choose up to five contacts you wish to notify that you are OK when you press the OK button on your SPOT. Choose email addresses or send an SMS to a cell phone.

HELP feature - you can choose up to five other contacts you wish to notify if you need non-emergency help.

Tracking feature - with the optional tracking service ($49.99us/yr), give access to who you want to log into you watch your live tracking.

9-1-1 feature - if you need emergency help, SPOT is there for you. It notifies GEOS who is able to dispatch proper help based on your location instantly. Need an ambulance on the road? No problem. No charge.

Search-and-Rescue feature - with the additional SnR Benefit ($7.95us/yr) get up to $100,000 of Search-and-Rescue service. Need a helicopter off the road? No problem. Need evacuation from a war-torn country? No problem (seriously).
