GPS logger (very long battery life)?

1

Does anybody know about GPS-Trackers?
I’m looking for one that has LONG multi-day (multi-week?) battery life.

To save battery power, a gps Tracker doesn’t have a display, and doesn’t process the GPS information, leaving the actual processing of the raw data to be done by a computer after you get home.

Erin & Hig mentioned using one on their groundtruthtrekking trip, but didn’t provide details.

Any help would be appreciated.

Perhaps also ask on GTT via the contact page.

SPOT trackers might be worth a look.

Defiantly check out the spot gps tracker. Good battery life and can exchange batteries (AAA’s) on the go. Also is a good emergency item. Used mine for a cross Canada expedition and lent it to a friend cycling down to Baja.
