RE: Blue light or Blue Blood Tracker?
I also own a streamlight stylis which is green, great for getting to and from the stand or digging thru your bag in the treestand, but worthless on the track job. A battery powered spotlight is an excellent idea that was mentioned before. One elemental truth if you hit them in the right spot any light will do, because only only reason you need it is to field dress your deer in the dark.
