How about these hikers in the mountains in winter who may not have much money. Could they buy a good radio beacon for $200 or so? What is the entry point for such an item?
You asked me a question I don't know the answer to. I am fairly certain that there is no cheaper EPIRB than the 406's, which are around $500.
I notice that we have the ability to track some terrorists through their cell phones, so possibly there is some cell phone related device than can fix a position? One thing I do know is that an accurate hand held GPS can be bought very cheaply...anyone who is in cell phone range can call for help with a very exact position. I understand that you can now also buy an antenna to attach to a cell phone which can add range if you can figure a way to get it higher up.
Ramius, what solutions do you hear of for such things?
