Hi Guys,
	  I believe it is possible to get small personal EPIRBs, and with the
number of divers lately who have been left behind or drifted off in
currents I have been wondering about their use in diving. I recognise that
it would be best to ensure you don't get into this kind of situation but
things can go wrong even with the best planning.
I confess to having very little knowledge of how EPIRBs work so
some questions if anyone can help me:

- roughly what size are they?
- what sort of depth rating would they have or do they require a housing?
- would batteries be user replacable
- are these small units "powerful" enough to do the job (ie signal strength
- or does the signal go via satellite)?
- when an EPIRB is activated who actually receives the signal?
- are any/many divers using them (if not why not?)
- any particular brands better than others (any web sites)? 

Sorry if my questions are a bit naive but i am just trying to find out if
this is a useful concept or not.

Thanks,
		Dave.
