Could one of those laser pointers be used to signal a plane at night ...
or a bright yellow smoke cutter flashlight that you can light up a water tower with during a house warming party until it's taken away by someone's wife...but I'm just sayin...
I would not recommend pointing your "Laser" at aircraft. Pilots don't like that so much, and you'll have some G-men knocking on your door.
I think that headlamp on strobe would suffice in a nighttime signal/rescue situation just fine.
I've considered one for use as you described...not sure if it would be in a BOB, but backpacking and stuck on the side of a mountain above treeline, at night it would be VERY easy for SAR to pinpoint you. The occasional "searchlight" wave for 10 seconds every half hour maybe...but for God's sake, the LED headlamp is visible from WAAAAAAY off...especially if it's on strobe, if you have that feature. We watched a night hiker descend Humboldt (a 14'er) in CO...he was wearing his headlamp, and his basecamp buddy sat on a rock with HIS headlamp on so the guy always had a bearing. Pretty cool stuff.Think about this you get lost in lord knows where and you are twisted around for some reason or break a leg what ever. You see all kinds of lights on a hill across the the way all you gotta do is get near them and get there attention they can see the beam all the way back to where you are. I never said anything about hitting any aircraft so the 12 year old made the mistake. Monkey see monkey do perhaps or maybe even lack of supervision with something that powerful.
Light easy, easy to carry, and small. Any advantage helps if in trouble.
oooh..I think I like your thinking!I've got a laser. On my rifle. But it must be broke'd 'cause I can't see the dot without a PVS-14 mono. I might give it back and ask for another one that ain't broke.
I can't think of many uses for a visible spectrum laser pointer in a survival situation. As mentioned above, don't be shining it at aircraft - it's bad ju-ju.
You MIGHT be able to make a visible signal by running it over a space blanket when a SAR bird is nearby.
I'd probably stick with a strobe. The newest ones take AA batts. The older ones can easily be modified to take CR 123s in place of the big magnesium stick. I've done it - lots of fun.
OK then, I'll tell y'all how -
Get the expended battery and place it on some lit trioxane bars or a twig fire between two big rocks or bricks
Wait 5 mins or so until you hear what sounds like a pistol shot as the battery explodes
Find the brass cap off of the battery
stick two CR123s into the strobe upside down and screw on the brass cap
Works damned well. Can you get rechargable 123s?
