there is a revised model SPOT coming out, see here:
http://www.equipped.org/blog/?p=113It addresses some of the issues.
As somebody said, you can't fix stupid.
There are thousands of responsible SPOT users that don't cause goofy incidents like this one.
I have one & so do several of my riding buddies.
Should we be penalized because fools rent & misuse the equipment?
I know - mostly from this site - that the SPOT has some shortcomings.
We like it because I can use the 'OK' button to let my wife know all is fine even when there is no other way to communicate.
I've had it over a year & so far the 'OK' button is the only one I have used.
Plan to keep it that way.
