Using a 50 mm objective lens and a charge-coupled device (CCD) array for enhanced light detection, Pulsar’s N550 Digisight Riflescope can effectively sight-in targets several hundred feet away in near-darkness.
The image is translated onto a 640x480 pixel, contrast adjustable, black and white digital display. The visual array is fully customizable with six preset reticles to choose from, a mini-USB port to upload others, and various information displays, including time and battery-life monitor, all of which can be hidden for an unobstructed field of view. A built-in infrared (IR) illuminator provides additional lighting, undetectable to the naked eye, in the darkest environments; and a Weaver 7/8-inch rail, mounted on the left side of the scope, allows for attachment of additional IR flashlights or other accessories.
The N550 can be zeroed using traditional techniques or with the “one-shot” zeroing feature that, by observing and digitally marking the point of aim and point of impact, automatically adjusts the sight’s alignment. Other features include easy installation on most rifles with the supplied mount, a video in/out port and a remote control. The unit is powered by four AA rechargeable batteries or an external power source. Price: $1,400.
