I don't know how many times I've stumbled over a rock or branch on my way to my stand in the pre-light hours of the day. While sneaking through the woods, I trip over a branch and go crashing ahead as I try to regain my footing. The deeper you go into the forest, the darker it is and the harder it is to walk quietly.
So I started carrying a flashlight. I used the small mini-lights that were both lightweight and bright. But you could see me coming from a mile away and I'm sure the animals saw that light even better than I could. I tried putting my hand over the light and opening my fingers up to let just enough light out to see the trail. It worked but I still gave off way too much light. I bought a head lamp that had a strap that went around my head so I could go hands free. I liked it a lot and loved it after dark at night when I was field dressing an animal.
Then I found one that had just the ticket.... it could be switched from bright white to red. The red gave off enough light to walk through the darkness but wasn't nearly as alarming to animals. What made it so good was that it had both, the white and the red. I use it to walk to my stand in the early morning darkness and I use it for hands-free field dressing after dark at night. I wouldn't be without one now. They can be picked up at most sporting goods stores and they don't cost an arm and a leg. I keep it in my day pack at all times.
