I do a lot of my riding solo. I'm 61yrs old and recently broke my collar bone on a very secluded ride and luckily my wife was with me but it's common for me to be riding out of town where there is no cell phone coverage or back on a dirt road with no cell phone coverage and potentially no traffic of any kind for days so it's been suggested I get a emergency beacon kind of thing that I could set off to alert folks as to my whereabouts. Ideally it would show where I am at all times so in the event of something like a heart attack or other disabling accident I could be located even if I were unable to activate it myself.
I haven't begun any research on this but I know there are such things on the market. Our family all has an iPhone app that lets us track each other when we are in cell phone range, if anyone bothers to turn on the app ...and that kind of feature would be great so my wife could note that I've been stopped for too long at some spot. You get the idea.
Anyone with experience with such devices? Small enough to take when on a road bike but satellite based and not dependent upon cell phone coverage?
