This story was told in 2007. A used entry level marine GPS was in the $700 range at that time. Current map was $200 extra. In the boondocks there often isn't much price difference between used and new, so the price could have been in the $1000s also.

A used long-range radio could be cheaper, but not that much.

Both could easily be a year's earnings.

Satellite Phone was in the $10000s.
