Pulsar Night Vision combine a number of great features to give you the performance necessary for success in low light situations. First, Pulsar NV Goggles and Scopes gather a tremendous amount of light for their given generation. That's why you'll see a plus sign next to some Pulsar products. It may use Generation 2 Night Vision Tech, but that tech is so well refined that you'll get much better resolution than most other Gen 2 NV. The second great feature incorporated into Pulsar Night Vision Devices is durability. All the awesome technology in the world won't matter if the optic breaks down because of small amount of shock. This is especially important for Night Vision Riflescopes, as recoil can wreak havoc on electronics. You add in smart features like Bright Source Protection (shine a bright light into most night vision devices and you'll ruin the tubes) and ergonomic designs for easier carrying and use and you have a truly fantastic night vision device from Pulsar!
