Night Vision Quick Focus Caps

Using NVG’s for a multitude of Law Enforcement tasks presents some challenges from typical white light jobs. One of those challenges is that the NVG is focused at a given distance, typically at infinity. The problem with this is when you need to see or examine something at close range. This requires that the NVG be manipulated to change the focus point, which in turn creates a new issue being that you cannot discriminate something at distance because it is blurred. There are a few remedies for this, one of those remedies is to make a tight “OK” hand signal and place that over the objective lens. This blocks the number of photons entering the tube and changes the focus to being much closer. You can adjust the size of the “aperture” by simply making a tighter or looser “OK”. Benefit is it’s free and you always have it, down side is trying to determine the right size and also manipulate other things with the hand that is occupied making the “OK”. Several manufacturers make focus caps, they range in price from over $200 to $9. They all do the same thing, reduce the numbers of Photons entering the tube

LE use of NVG for Warrant Service – One Cop’s opinion.

I have been a SWAT dude for over 20 years, during that time I have seen huge advances in tactics, techniques and procedures as well as gear and supporting equipment. Indeed, I tell new guys that I wish I was starting my SWAT career today versus being at the end of it. We have come a long way since Balaclavas, Command Jac vests with K30 plates and MP5’s. A big reason for this growth and increase in skill is directly related to the GWOT. America’s heroes in foreign lands have discovered that technology, when used correctly, is a force safety multiplier unlike anything else. This is particularly true of night vision capabilities and supporting gear. It is far past the time that domestic LE catch up. As I said earlier, I’ve been kicking in doors since 1995. Since NVG technology was nowhere near where it is today, and the cost was also extremely prohibitive, SWAT teams in America were simply conducting warrant service with flashlights when conditions were such that you had to see in the dark. Many different white light techniques and team tactics with white light have been developed and used over the years. During all that time,
