Live tracking VS SPOT at Big Spring
Fint med fyldige data men så var det sikkerheten da..

«Q: This is a really cool app… can I get rid of my SPOT now ?

A: Think about that decision carefully. A SPOT tracker sends up a distress signal via L-band satellite, which is then dispatched globally based on where the signal came from. It has one, and only one purpose – to save your ass. While our tracker client can do a lot, it does need a cellular data connection to get the data out. While coverage is good in much of the world, I still personally fly in places where (from time to time) I get no signal at all.»
