At long last, WITC took the plunge and purchased a new GPS. A brand new shiny Garmin Dakota 10. Sure, there are bigger and better things out there, with mapping and stuff, but this is more than adequate for us, and it was a bargain £90 on eBay.
Out on it's inaugural walk (above), and we are really very impressed. Clear display, good battery life, accurate and good satelite locks. Recommend.
