Would be great to be able to pair this with a small solar charger.
Also, do these work internationally? I went scuba diving in Indonesia in a place with strong currents. Saw amazing creatures, but there was a story overhanging everything about some divers that had been swept away by currents, landed on an island inhabited with Komodo dragons & had to fend the lizards off by swinging their weight belts at them. They were found a couple days later, but badly sunburned and exhausted. Amazing!
