Lumaglow and lasers?

[sniper 55]

Lumaglow.
While shopping I was given a piece of something called lumaglow (luminous fabric) about the size of a business card, although it comes in big sheets. I tried it out and once exposed to a bright light it glows quite brightly for about 2 hours but is still visible after 4 hours. I think it might be useful as say a marker in the pitch dark, the bit I had was just about bright enough to read a map (part of a map anyway) if held up close. Don't know how much it costs though. Not sure if I'd buy it, a glow stick gives off more light, but then you can use the fabric over and over.

Lasers.
A contact in the US tells me the big thing with preppers there at the moment is lasers for siginaling for help, apparently you can get these high powered ones that can be seen for miles if just pointed up.
Now I am wondering if the small ones will work if just pointed up at say a tree, I think that could be seen a good way off at night.
Anybody tried either of these or any thoughts on them?

Thanks

Had a play with some a bout 6 months ago UK legal ones are a joke, but i found mine on fleabay for about £18 quid, on the box it says 500mw or something on those lines but it's way more powerfull then that, i was told to look out for adverts which catch a match on fire, i did try it but failed to work for me.

However on a clear night i did take mine up to Blackheath and was able to hit Canary Wharf without too many issues, which i reckon is about 3-4 miles, no idea if this is considered "good" or not but i was impressed, you may want to check out http://www.megalaseruk.com/laser01.htm for more options

I like the link to the lasers. The pen one looks very classy - comes with Dolce & Gabbana batteries!

More like Dave & George.

One thing i forgot to mention was the high power uses a weird battery it's AA like but a bit fatter and a bit longer, batteries and charger are cheap enough on ebay, but if you do get a strong for fooks sake be careful or your and others eye, when i got mine i was playing around in the bathroom and it hit the mirror and bounced back into my eyes for a split second and for 20-30 all i could see was green lights, so treat with caution

Good point. I guess also be careful when using outside and avoid flight pats, otherwise you may be having a conversation with the boys in blue.

I'd say 3 or 4 miles was really good, most of the ones I've seen are good for a hundred yards or so.
You make a good point about safety, theres a lot of reflective stuff about, it's supprsingly easy to get a reflection back from something, and in a survival situation an injury is the last thing we need.
I've not managed to get myself with a laser.... yet, but I did managed to blind myself with a many thousand Lm torch a while back.
I'd got one of those skyray king ones, think it was 9000 Lm or something silly like that, anyway no instructions and a strange battery layout meant I was playing about trying to figure out why it wouldn't work (it turns out all the batteries go the same way) and I managed to turn it on with only one battery in it, and of course I was looking at it. I was properly blinded for a few minutes, stupid thing to do, but I didn't expect a torch with 4 batteries to work with one.

18500's?

if so buy protected cells... as none protected rechargeables are easy to discharge and they then die or over charge and they catch fire......

I did a bit of temping with a lad you had just left the army and he was telling me about a thing called "Buzz Saw" which is a British Army Cyalume Signalling Device on rope, his sgt instructed him to signal the helicopter and as he was swinging it around it sheared off,

more info on the device,

Cyalume brand chemical 6"/ 15cm snap light with cord.

IR with minimum 8 hours of light output. These invisible to the naked eye, and can only be seen through an image intensifier.

Fitted with 1m of issue nylon cord, this allows the user to spin the Cyalume on the cord creating a 'buzzsaw' effect, increasing the visibility of the light. This method is in use with some military units for self marking by casualties or ground to air signaling.

Excellent lightweight emergency light source with 360 illumination.

Suitable for multiple uses including markers, map reading and identification.

Waterproof and visible up to a mile, no sparks and no batteries to run down.

The name says it all; snap and shake for continuous (black) light for up to 8 hours.

Weighs just 22grammes and fits into a pocket or pouch, genuine issue item.

Just a thought, Be Safe Citizen "H"
