I got this for a birthday 4 years ago. Every year we go on a week long excursion. 2 years ago a friend of mine got lost on a boat on the finger lakes in a bad storm. We went out with this flashlight. They said they spotted the light from, had to be, 2 miles away. Everyone made it back safe. This is a good all around flashlight. Adjustable for small jobs, very very bright for times you want to spoil yourself in the wilderness. Just bring extra batteries.
No surprise here, there is a reason Surefire lights are expensive, because they are the best lights available today. This is an easy to carry light that adjusts from low to high intensity with a turn of a dial. Left is low, turn to the right and there are five increasing levels of brightness. This is a perfect design allowing a low level or high level of light selection prior to tuning it on. The U2 is military spec and at the brightest setting provides 100+ lumens of tactical brightness. If your safety in dark areas depends on a flashlight, spend the money and get the best. Once you get one of these in your hands and try it in the dark you won't think about the price ever again.
I carried this light while working for the Cal Highway Patrol and would use it often, also I am never without this light when hunting, camping or anytime it might be needed, a great light. Some what pricey but well worth it, you will never be without it once you own one.
