Night owl igen - Night Owl Optics iGen 2.6x41 mm Image Capture Night Vision Monocular NOIGM3X-IC

These are the best I've used ever. I would have to compare them to @ least gen 2 optics. Great clarity. I highly suggest that you follow directions as pertaining to the batterie's , I installed my first set using one batt. that was almost new as that was all I had on hand and couldn't wait to try theses out and they went down super fast. After installing all new batts. they are still going strong.Thanks for the Great Night vision.
