This is a solar-powered GPS and track logger. It does the things that I’ll be using my Garmin Etrex for on the tour (still delayed due to the worst summer I can remember for many years!) but in a much tidier way. Transystem Inc, the manufacturer of this product already have a solar powered GPS unit called the I-Blue-757 which appears, in specifications, to be similar to this one so I’m not sure exactly what the difference is. Here’s a picture of the I-Blue-757
If I can find a local supplier for one of these, I might get one to test out although The Etrex is hardly taking a huge amount of power and is proving to be reliable and rugged. I’ll give it some more thought I think!
