SPOT Satellite Tracker mounted
I use a SPOT Satellite Tracker on my snowmobile so friends and family (or anyone I provide a link to) can follow my rides in near real time on Google Maps. Plus it has a SOS button to summon emergency help if needed and a couple of message buttons.
Now when I go on long bike rides I can slap the SPOT on so people can see where I am.
Found the perfect spot to mount it...on top of the brake reservoir.
