The SPOT locator works like this... You're out back country skiing with some friends. The last one down the steep tree shot is you. As you're shredding downward, you hit a small hidden branch and tumble a few times stopping only with your back hitting a tree. Perhaps it is a broken rib, or maybe, worse, a back injury. You slowly remove your backpack and take out your spot. Clicking on the SOS button calls up emergency services and your wife. They are on the way. The SPOT sends a signal to you rescuers letting you know your GPS position. You're safe a few hours later... Now tell me that isn't worth it! Click here to buy yours now!
