If you are gonna track after dark a double mantle propane lantern works better than anything I' ve found so far. It is a little more ungainly than handling a flashlight but works pretty good when hung in a tree for illuminating your gutting area. The light from a propane lantern also seems to help illuminate a larger area at once so you can see the differences between the false red spots on the leaves and the real blood.
I ususally carry a lantern in one hand but have a 3-4 cell maglite in it' s holster. If I need more than the lantern I break out the maglite to help.
