My hunting partner has one of the Tim The Toolman Taylor models.
I think it's a bazillion cp "THOR".....Anyhoo, we've used it
twice this duck season running the lake to our blind at
zero dark-thirty. It serves two purposes. First, of course,
it turns a dark night into a not-so-dark night.
Second, and just as important, it puts out a lot of heat...
That is a good thing when you're zipping along at thirty mph
in an open boat with an ambient temp of 19 degrees.
The downside, is my buddy had to have his pants altered to the
light would fit in his pocket. It's is EDC now.
