An EPIRB would probably be stowed below deck when out at sea in my kayak where a possible emergency situation could see me getting separated from my vessel.
No good having that emergency beacon below deck then...
While my PLB is small and light enough to not be felt when paddling I have not been totally satisfied by its reliability.
Is SPOT the perfect tool?
I would like to see the ability to send out more than just pre-recorded messages.
I hope that in the future SPOT will offer a unit that might do that.
Or maybe there will be an "emergency beacon" app for the iPhone :-)
