Answer is "Yes, probably work very well" -- esp. if you get one of the
green ones, though they're substantially more costly than the red ones
($150 vs $15).

Post your query to sci.optics or rec.skiing.backcountry and you'll
probably get more detailed answers.

I would add that if you do get a pointer, green is the most visible,
and keep it to a legal 5mW pointer. Pointers are limited to 5mW
for a reason - it's *extremely* unlikely to cause any eye damage.

If you go down at night they will most likely be looking for you with

Or would it only get me arrested? (After rescue, of course...)

Jay, check out www.equipped.org. There are tests done on laser pointers
as signalling devices. There are also leads on aviation quality signalling
mirrors for about 10 bucks. Also, great articles on ditching.

Why wouldn't you just use your handheld?

As long as you get rescued! In the winter in the north the cot for
sleep and 3 squares of jail would be welcome....

check out www.equipped.org for more info on the rescue flare/laser flare
that is being SOLD as a rescue signalling device (basically just a heavy
duty bright red laser pointer....

Green would be even better.... My green laser pointers dot is visible on
a water tower 1 mile away!
