This product is inexpensive and readily available and leaves no excuse for not retrieving your deer.
AT is the most amazing resource that apparently few bothered to use, just wanted some sympathy for not getting the deer they shot. Listen up, they don't all bleed out the way you think, double lung one, it is more likely to bleed internally, hit the liver, it doesn't bleed much at all but it's still dead in 4 hrs.
BlueStar and a clean and empty household spray bottle, add some water, wait till dark and find your deer.
On another note, there is usually a blood dog available to call upon. Asking 20 guys and someone's pet dog to track for you is not an answer. Go call your local shop, get the dog handlers number and keep it handy, get BlueStar to have on hand, even if not for you for one of your hunting buddies.
