Repeater coverage is patchy, but when its available its reasonably well monitored. The PLB is the real back stop for serious emergencies. Mine is GPS enabled so the fix time is around 5 minutes (somewhat more for somebody to actually get to you ). Without GPS, it can take half an hour or more to triangulate a position fix. I carry a fire extinguisher, a decent First Aid kit, and a snake bite kit all the time too.yeah i agree for emergency but there must be something out there
