After finding out that my trusty Garmin eTrex is no longer supported by Garmin, has no Mac drivers, can’t connect to Basecamp, etc… I’m now on the lookout for another GPS that is small, light and has battery life approaching 24 hours.
Every “watch” type GPS that I have found on the web seems to have a good battery life when used in watch mode, but then falls to about four hours when the GPS kicks in. Since this is going to be used for training for my 69 mile thingy, and I plan to be out for a damn sight more than that without charging facilities, I need something that will last a lot longer (probably up to 24 hours) or lasts a lot longer and runs on replaceable batteries (like my eTrex) so that I can swap them out for fresh.
So far, the only wearable option seems to be the Foretrex 301/401 (do I want to sacrifice an hour of battery for a digital compass/barometer?). Does anyone have any other suggestions?
