In a perfect world, every archery deer is double-lunged and tips over within eyesight. In the real world, it’s more complicated than that. By ranging from your bloody arrow back to your tree stand, you’ll have better intel at the start of the track. Then, if you get turned around in the process, you can range back to arrow, tree, or a terrain feature to help orient where you are, and where the deer went. Know how far your deer ran after the shot, or how far out you are from the last blood on a difficult track. On evening hunts, this work often happens after sundown, so you need a tool with incredibly low-light ability.
