Bought two units - Armasight NYX-14 GEN 2+ MG Multi-Purpose Night Vision Monocular

I use two monoculars set up with a dual bridge and find them very capable under moonless nights, capable of IDing targets out to 50 yards with no ambient light. Under ideal conditions, you can easily ID anything at 200+ yards. I see very little difference in image quality between SD and IM units. I accidentally bought the different units. The only downside to using them as a pair is the weight. The pair bridged, weighs twice as much as a PVS15. These are best utilized as a monocular if you'd like to save weight.
