Does anyone have any first hand experience with blue light? Apparently these blue LEDs will make blood practically glow in the dark, which would have been a handy thing this fall. 2 hours of crawling in the dark for a friend's son's buck really got me thinking about it. We did find it, it ran 250 yards with a good muzzleloader hit, but they lost their daylight.
The two that I've heard of are a $70 Gerber and a Surefire for $300 ish. If they work, that's cheap.
Any thoughts, gimmick or gold?
 
I didn't find it 'glow' - if anything it made it black. But that did make it stand out a touch.

Here's a trick tho - buy yourself one of those keychain red led's (single led). It turns on when you press your thumb against the switch. Now turn your blue lite on, then use your other hand to 'blink' the red light on and off. The blue washes out the red light on anything EXCEPT that which is red (like blood). It will appear to make red objects including very small drops of blood 'blink' quite noticeably. It can be very helpful.
 
Try to get a bright uv LED, or a 12v black light flourecent tube. Blood, and bodily fluids will fluoresce under uv, or 'black' light. It's good enough for Forensics.
 
Amazing I really didn't think of that.

Something like this would so have come in handy two years ago when my uncle shot a deer just before dusk and it bolted. We ran out of light on the blood trail and had to come back the next day.

There are some flashlights that come with a blue and red filter to put over the front. i know one maglight that has it, but would probably want something more powerful.
 
I own a Gerber and never found it all that great on leaves and such , but I will say that I killed a doe last night with the bow and as I tracked her for 30 yards with a white light I could not find blood, untill I turned on the Red/Blue light. In the snow the effects were 100% better , turned frozen spray that looked like fine dirt in the snow into Red fresh blood, very easy to track...
 
Adrian J Hare,
Finding the first blood is often the hardest part.Anything that helps with that has to be a good thing.
I'm finding the Surefire Kroma for $230 on ebay now, that's a little easier to swallow than $300 for a flashlight, even if that's all it turns out to be.
I was sort of hoping someone would describe the Surefire as the coolest thing known to man, thus making my mind up for me.:D

I've got 4 of them set up in various ways, and I'm already eyeing up my fifth.

Now we're making progress!:D Are you running the high end Surefires or the more basic setups? I can get 5 lowend lights for the price of one of these Kromas but they don't have the blue/red feature. Ironically Costco will sell me 20 Maglights with batteries for the $300 full retail of a Kroma.
I've about decided to buy one.
