I purchased the Surefire M3LT. The reason was that I wanted a darkness blasting tool to spot wildlife while out on walks...not spotting in the negative sense that poachers use. But rather just to be able to see critters at all. Here in Texas that light allows me to see the reflective eyes from great distances. I've seen coyotes, hogs, possums, raccoons, armadillos, deer, beavers, etc when I otherwise wouldn't have noticed their presence. And this is all within city limits, which is amazing in itself how present wild life is around here.
