Has anyone used blue filters for night blood trailing?

I've been reading about using a blue filter on a flashlight for blood trailing at night. The blue light supposedly makes the blood show up better. Has anyone tried this? Did it work? Do you know where I can get a blue filter for a maglight (I've only seen them for mini-lights). Any info would be appreciated. Good hunting to all!

This is news to me and I'd be suprised if it worked. Its my understanding that blood forensics requires coating the surface that may have blood on it with a chemical that binds to the blood and causes it to fluoresce (glow) under black (ultra violet) light.

If anything I would suspect that a red light might help to make a fresh red blood trail stand out from a dark background (little help when the blood oxidizes and turns brown). This works on light absorption/emission differences and not the same as the fluorecing mentioned above.

So while I can't say for sure it won't work well, I have my doubts. I would just take a blue piece of cellophane and rubber band it on to a flashlight to experiment first.

The spray you wrote about is luminol. The blue filter thing is a little different, I have seen kits that came with yellow tinted glasses which is similar to what you see on t.v. but I've also read that it works without them. The blood is suppossed to show up as dark spots. I'll try to find a link to post.

I bought a mini-light with the blue filter, I'll let you know how it works if I can get close enough to a deer to put a hole in it.

The guy that tought our bear clinic here in Minnesota says that if you use a gas powered lantern (Coleman) the light emitted will cause the blood to glow

Well, I tried the blue filter thing last week and it didn't work well at all. The blue light didn't seem to highlight the blood at all and even when I looked at blood that I already found it wasn't any easier to see. It realy would have helped too because I gut shot the deer (a doe) and the trail was pretty sparse. With a lot of persistance and a little help from my brother, we were able to find her. I aimed a little far back because I was trying to avoid the shoulder. My arrow flew well but I missed by a few inches, I even hit a rib on the other side. I wont make that mistake again, the next one goes right at the heart. I'm going to keep looking at the filter thing I'll pass on any info I find. Good hunting to all.

The best thing I've ever seen personally for game recovery was a unit called a GameFinder. It's a hand held unit that detects heat. YOu pan it left and right and a set of lights would glow when it was pointed in the proper direction. Shot a deer right at dark one evening and it ran off. I went back to the house to get a coleman lantern to track with. My friend just happened to be driving by and said he could find the deer in 5 minutes no problem. Mind you its pitch black at this time, so I was quite certain that he couldn't. Needless, to say a wager followed and we headed out. when we got to my stand I pointed the direction that the deer had gone. Out of his pocket came something that is best described as more likely to be seen in an episode of star trek than in the deer woods. Well, that thing-a-ma-gig led us directly to the downed deer some 200 yards away without even a bobble. I since have looked for one of my own, and was informed that they had been outlawed in my state. I guess unscrubulous people can use them to increase their odds of killing an animal.
