Have just posted re an app that I and just about everyone I know has on their phone now - called Emergency +, is invaluable, uses gps technology - this is just the situation where it is needed. When you hit the 000 (for instance) your co-ordinates, address (where you are) and map, is sent to the authorities - if they can't ring you - there will be an alert out to authorities in the area. I personally would send it a couple of times, so they know it is genuine.

That's a very good idea Dannell,

I've been looking into the price of these units recently,  and I'm quite surprised how cheap they are to buy,

only a couple of hundred Bucks on Evil Bay,  and well worth the money,  I will be ordering one before our next trip away.
