I used a Nite Lite for coon hunting when I first started and it was good for a starter light. I let people that I go hunting with use it now. Convenient back up. Now I use a Bandit Belt Light with a Spotlight and walking light connected as well. Great light. A lot of my hunting buddies back in Indiana use them as well. I have had mine for about 4 or 5 years and still burns just as good as the first day I got it. No complaints.
