My PLB makes my Mom happy (well, less worried anyway). You must purposefully snap the cap/back off, unwind an antenna and then push the button. It can not be used again until it has been returned to the company and reset. (Since, theoretically, you were in serious danger, you are now probably in traction and won't be hiking in the next week or so anyway.)

I can't imagine setting it off accidentally, and the owner gets TONS of information with the packaging and then online when registering the unit. This includes an "I agree/understand" statement. It is absolutely shameful that anyone would abuse this technology and it really makes me mad [angry cat face].

If you make a false call, you should pay. I don't think honest emergencies that were not entered into during particularly dangerous settings or weather should incur a fee, however, I'd still be willing to pay for my own rescue - at least some of the cost.

Ooooh, I'm mad now.
