Like stated above limit the distance of your shots if the first step. Never over 30 yards.

Wait at least 30 minutes but 60 is better. If a gut hit, wait several hours at a minium. If he's dead he'll still be dead 5 hours later...

While he runs off watch his feet. Pay attention to where his feet last touched the ground. Easier to reference where he was. Theres usually a stump or branch , something to mark the last spot you saw his foot touch the ground.

If it's getting dark look for your arrow while still waiting in the tree with binoculars. You may find the start of the blood trail before youeven start down and while it's still light.

Go slow.. Drop TP while you're moving along, it may help show the general direction of travel.
