"irradiation angle of one degree practicality zero Ultra distant irradiation head"
Wow that thing looks cool, it is just the head and screws onto one of several different flashlights and makes that narrow beam out to 600m or more. Looks like a great idea. I can't find the buy link either, or the price.
Edit: oops I just noticed its part of their discontinued products list. Maybe they are out of them now.
