Gen 1 Night Vision

1st generation is currently the most popular type of night vision in the world. Utilizing the basic principles described in detail in our guide, a 1st generation unit will amplify the existing light several thousand times letting you clearly see in the dark. These units provide a bright and sharp image at a low cost, which is perfect, whether you are boating, observing wildlife, or providing security for your home. You may notice the following when you are looking through a 1st Gen. unit. A slight high-pitched whine when the unit is on. The image you see may be slightly blurry around the edges. This is known as Geometric Distortion. When you turn a 1st Gen. unit off it may glow green for some time. These are inherent characteristics of a 1st Gen. unit and are normal.

  • From Beck at 4/26/15 7:40 PM

    • Q: Can you see objects/persons in total darkness using this monocular?
      Thanks!

    • A: Hi Beck. Polaris 2.5 Night Vision Monocular like other Gen 1 NVM's simply amplifies the available light. If you are in real total darkness like a windowless basement, you will need some source of light. For this purpose Polaris 2.5 is equipped with an IR Illuminator. this illuminator functions as an invisible flashlight. So in short the answer to your question is yes, but you will need the IR to be on and you should not expect a very long viewing distance. Since this is a standard Gen 1 monocular you can expect 40-70 yards depending on available light.
