Tracking a deer is not a race. Go slow. Don't be afraid to look on the sides of the trail ontrees leaves etc that are up off the ground.

Don't take too many people along unless you are done attempting to follow blood and are doing a grid search.

Follow the blood trails of deer you see go down to get practice.

If the trail is sparse or you've lost it for a bitdon't always assume the deer is going straight. Look in every direction while standing on last blood. Last blood is your friend. Always keep it mark and go back to it when you can't find blood in the current direction.

Deer can lose a seemingly amazing amount of bllod before they die.

Other than the rules on waiting, also keep in mind that when trailing a deer, nothing is 100%,they "generally" do certain things but if you've covered all the "generals" they start thinking outside the box. Sometimes they don't go to water, sometimes they don't take the path of least resistance.
