Greatly extended the range of my night vision binoculars - Streamlight Tactical Super Tac C4 LED Flashlight

My night vision binoculars didn't come with a built-in IR light. They're an older model Russian-made pair I've had for 10 years or so. They work well on moonlit nights, but have very limited range in total darkness. It's amazing how much further I can see with this light. There is a fence about 200 yards from my house, and I can clearly see it at night with this light. It does have a fairly narrow beam, and if it's foggy or misty the range is greatly diminished, but I suspect that would be the case with any IR light. There is no way of determining if it is off or on without looking through a night vision device, so I make sure I've turned it off before turning off my binoculars. Overall I couldn't be more pleased with the light and OpticsPlanet's service.
