They were Panasonics, 4 for a dollar!

Uh-huh. So..., how many amps does this GPS draw?

I thought I'd throw it overboard because with it's light on it was eating
batteries. But it was clearly the batteries themselves. I grabbed a half dead
pair of Energizers from my spare GPS (A very old Garmin 38) and they powered
the Garmin Map76 for the rest of the trip.
