FastFind VS. SPOT Personal Tracker
McMurdo sells a case which in my opinion seems better suited for storing the thing in a drawer, than on your person. The case cover doesn't look very secure, and appears to be held closed with only a little Velcro, and held in place with a simple clip. They want $20.00 for it.
The front is plastic, so the unit can be more readily identified as being a rescue device, in case someone other than yourself chooses to activate it.
The Mortorolla case closes with only a small Velcro tab, but the unit fits so snugly, it is unlikely to ever fall out on its own. However, I added a snap enclosure to be on the safer side.
I picked up a few, new cases, and if anyone wants one made up for them, feel free to contact me via this list. Twenty bucks should cover my time and shipping costs withing North America.
