All good advice.....I think time is the most important aspect. You have got to give the animal time to die without pushing it and you must spend plenty of time looking for the animal.

Volunteer your help on tracking jobs with other hunters. Tell them you are new to tracking deer and you want to learn. Most will be more than happy for you to tag along since you will be another set of eyes and another back to help drag. Tracking is not easy and the only way to learn is by doing it.
