IF it really works, it would be a good thing for recovery. My son and I spent about four hours the other day tracking tiny blood drips from a buck he clipped, lightly apparently. My arms look like I had a battle with a barrel of Siamese cats. While searching, I found a really nice 10-point another hunter had lost last Saturday. Tragic.
I'm not in favor of using such stuff for locating living, unwounded critters, as I think we have enough of an advantage as it is.
