We have hired Sat phones and epirbs for work trips before.
We looked into it and found it cheaper to buy a Sat phone than hire it - because we would use it more often. The call cost are now around a $1.00 min. Which is better than two years ago when we hired them and it was $5.00min. we bought a package deal for a grand.
Our company insists on us having HF, UHF, Sat Phone that are CDMA too. If there is no CDMA signal then it defaults to SAT Signal.
Think about this...How remaote are you really going? Is there going to be 100kms between you and the nearest 'living' soul. Sat phone is the way to go. They really are cheaper safer option. There are some brilliant plans out there. Shop around the net. You would be surprised.
Any man, in the right situation, is capable of murder. But not any man is capable of being a good camper. So, murder and camping are not as similar as you might think.
