LLHG is one of the courses I take every year, because night training is an essential part of being a competent defensive gun-handler.
MDFI's course doesn't just address firearm manipulation in the dark, and not just manipulating hand-held and weapons-mounted lights, it also stresses threat identification, defensive use of illumination, and the mechanics of human sight in low-light. Everything that's necessary for responsible decision-making and effective firearms use in low-light conditions. And, needless to say, MDFI's habit and history of range safety is maintained 100% by staff and students, even though it's dark out.
I've taken this course four or five times now, and I get something valuable from it every time.
Hats off to Trek, Tim and Derek for another A+++ training.
