A friend recently wrote me:
Quote:
I cannibalized an "AA" battery from my Garmin GPS and didn't replace it for a couple of days. Consequently, my Garmin's internal clock was 2 days behind when eventually I replaced the battery and switched on the handheld. Under these conditions (time error 2 days and location error a dozen miles), the handheld needed 20 minutes to synch time and location.

I would hope that PLBs have internal clocks for fast GPS synch time?


Does anyone know? Do PLB's have an internal clock? Is the question irrelevant since they don't have to snych up with a prior known time and point?

How long do PLB's take before they can acquire good GPS coords? I assume it's going to vary widely with terrain, but does anyone have a good link for this?

thanks!
