I recently replaced my old PLB (personal locator beacon) with a smaller model. So I have a spare FastFind PLB, never activated, looking for a new home. The batteries have expired but according to the tester lights they are still fully charged. Not sure how much it is worth so will consider any reasonable offer (I don't know how much it costs to get the batteries replaced).
