85R-3x44/5x50 is a first-rate Generation 1 monocular that provides a clear and clean image, it is very easy to use, making it perfect for observational applications.

At 200 yards the field of view is more than 60 yard which makes it ideal for viewing moving in low light conditions with a range of up to 50 yards.

The lens system allows for quick acquisition focusing to pin-point objects precisely and efficiently at night.

The unit s body design is very durable and comfortable.It makes the user’s experience much more enjoyable.

In addition, 85R is 15% more energy efficient than its competitors, resulting in a sixty hour battery life, what is more, the slide-in groove firmly holds the lens cap to the monocular to prevent misplacing the lens cap.
