This question was already asked about personal locator beacons (PLB, Wikipedia page which is a great comprehensive article.) However it does not cover how to choose a PLB or the differences between the cheapest and most expensive models. When I am browsing the models on the net they all look the same, but prices start at $200 and goes as high as $500.
- What are the criteria that should be taken in consideration ? (weight, supported temperatures, pressure, frequency used, etc..)
- Is buying the most expensive a better deal on the long run ?
