>Gears and Wears>Garmin 305 question
When it’s all said and done, will you have said more than you’ve done?
I think the specs said 10 hours - and you would probably have to be in Smart Mode to get that. I've never tested mine though. Maybe you could put a laptop in your backpack and charge it up via the USB port to get those last few hours.
Never used anything like this, but it looks lighter than a laptop.
