for what its worth, i actually got to use my spot in an emergency the other day. i came across a car crash in the middle of no where, people had been there for estimated 3 hours with no one having driven past. passenger was a bloke i know, he wasnt to bad, but having already suffered an injury resulting in brain damage 12 months ago, i thought it was urgent he got medical attention. Also to he was close to loosing consciousness. The driver looked to be in much worse shape, he was unconscious and had a face covered in blood.
it was surprising no one had found him as the accident happened near the entrance to a remote aboriginal correctional facility. that said however the facility is a working farm and people dont drive in and out of it much. though i knew it had police on site aswell as a stationed ambulance. I weighed up my options between leaving the scene to go get help, and setting up my spot. I felt it was only my communication keeping my friend conscious so I set off my spot.
now I had already noted the time exactly so i could make authorities aware of what time i found the accident, so i know for a fact it took exactly 12 minutes from me setting off my spot, to the emergency services group who receive the message to contact NSW police, for NSW police to contact the local police at the correctional facility, and for the police land cruiser to arrive at the scene....
now I dont think there is anything other way of looking at that other than pretty amazing! i was dumbfounded and overly impressed! always had the concern with the spot that i would never get to test its emergency capabilities until my life was at risk. now I can feel comforted that this thing really can save my life
