I went the RescueMe PLB1 route...because I walk solo in remote & rugged country,
...and mistakes & snakes happen.
So its piece of mind & maybe closure for my family too if I can't rescue myself or the team or helicopter
doesn't get there in time because of bad weather etc etc, at least they can locate my body.
But that scenario only works if I'm concious to push the button in the 1st place.
It's light, small & if you take it over the 7yr battery life & it's cheap life insurance @ roughly £30 per year.
Can be used anywhere in the world...now whether the country's rescue teams are up to scratch or even have
rescue teams is something to research before you go.
I'm thinking 2nd & 3rd world countries here.
Hiring a Satellite phone is another communication tool option if your going to really remote places & need
to touch base. Just hire for the duration.
Hope some of that info helps...
