I use it for aviation. A well made product with good diversity of beams. However, it is difficult to read/understand which selector position gives you which beam. Selector switch itself is not easy to use. So I find myself just moving it until I hit the beam I want.
Pros: Sturdy, good range of beams
Cons: Setting indication confusing
