As a color blind hunter, I am very interested. It would be great to be able to track a wounded animal without help.

bslchlacter- I used the same thing on my shooting preserve and hunt club in West Central Minnesota.The product you are referring to was called biotrack i believe. I had the same results from that product. After contacting the manufacturer, they sent me a case. One bottle out of the whole case worked. The rest had a reaction to any biological based liquid, so as you can imagine, the woods were "glowing" in a dull green where ever you sprayed it. From Mouse pee to blood it lit up all. This product was recalled shortly after I recieved the case.
The product Dave mentions is a forensic tool used by police in numerous investigations. Does it work for deer? Intuition and linear logic say it should, but I'll wait and see.

I have never used this product or any of the similar products on the market.

I can see this product being helpful in open grassy areas where the blood drops between blades of grass and may be difficult to see but even so how much of this stuff do you have to spray if you are looking for a drop of blood every 10 yards? My fear would be that you will spray this stuff on the ground but not hit the blood then assume it's not there because you cannot see a blue spot. Also, is there a possibility that the spray itself will wash the blood down into the ground and be invisible?

I don't know. I sort of like the idea of just looking for blood.

It'll be a good time for an article on tracking tips. Or better yet maybe I'll start a blog on the message board.

Put the smack-down on your deer and you won't need this stuff to track it. What next? Spray field dressing in a can?

I hear a poacher in the far north used this stuff for in an early attempt to stock his larder, but he lost the track when he came to his first blueberry patch!

What is used in the Police field does not sounds like it should be used in the woods. Although it is a good concept and good idea, it is not only expensive but also not worth it. My buddy used it once and a lot of things lit up and you end up with a sore back because you are bending over the whole time spraying everywhere trying to figure out which spot looks more illuminated. It also takes a lot of this stuff if you'r deer has run a long way... We found the deer but I think it could have been easier and less expensive if we hadn't used it at all

I've seen this product demonstrated at an industry show.

The show was held in February and part of their demonstration was to spray their product on the bed of a pick-up truck that had been used to haul a deer that had been bagged back in the previous hunting season. Despite being exposed to rain & snow you could see the blood evidence.

They use it all the time in police work. It was one of the most helpful inventions because all you had to do was shut off the lights and then shine this light. This is just a little different because it's a spray.
