| How tolerant of cold are GPS units. I plan on being in sub zero
weather. How carefull do I need to be. Thanks

I've carried my Garmin in some pretty severe weather with no
problems. (GPSMAP 76CS)

You should check the specifications on your particular model since the
answer won't be the same for all GPS receivers. My GPS V is supposed
to be ok for operation between 5=B0F and 158=B0F. Low temperature
affects both the batteries and the LCD so you may see reduced battery
life and sluggish response of the display. When it's colder than that
I keep the receiver and spare batteries inside my coat except when I'm
actually looking at the display.

| I think you have to use Lithium batteries. Any other type will not
produce the right voltage at very low temps. Check the FAQ on
Garmin.com

Dunno if you have to, but litkium ion batteries are all that
I use in the GPS and our cameras. I'd highly recommend
using, or at least trying them. They aren't cheap but they
work.

The batteries are going to be the most critical thing in subzero temps.
We used Mercury Batteries in all our High Altitude Climbing Radios
when in subzero temps. These are not rechargable, but they do function
clear down to -60F and always were very reliable.

Batteries may not be the limiting factor once you get below 0 deg,
unless the GPSR is designed to work in very cold climes. Most Garmins,
for example, are not speced to operate at -60 deg F.
Plus, do they make mercury batteries in AA format?

Probably true. When I said that I'd used the Garmin in
pretty cold temps, it was nothing even close to -60dF!!
MAYBE -5 or -10dF at the worst.

I'm not sure that you can get any mecury cells at all these days - it's a
big problem for people owning old cameras unless you can get them modified
to use silver oxide cells without throwing the metering totally off.

Cold weather solution on my snowmobile.
Screen would start fading at about 10 degrees F so I attached a heater panel
between mount and GPS. I also run the GPS off the sleds battery.

Yes, Mallory Battery makes AA's....

I used my Etrex Vista on a glacier touring trip lasrt year. Not too
cold maybe -25C most of the time). Functioned perfectly using
standard alkaline batteries. The trip was only 1 week long so I
required about 3 sets of batteries.
I've now upgraded to a 60CS and will see how it manages this winter. I
expect to use a lot less batteries. To date my trips with the 60CS
have been short (only a day or two) and I'm using rechargeable NMh
cells without a problem at -15 to -20.
I'm not sure how much colder it has to get before Lithium cells become
a real requirement.

much.

I don't think so. I'm sure that Hg batteries have been banned for many
years.
I thought that the Mallory Battery Co was now Duracell and they certainly
don't include Mercury in their list of current battery chemistries.
