One of the remarkable features is the possibility of zeroing the riflescope not only in the traditional manner but also using a new “one shot zeroing” method. This makes the zeroing procedure significantly faster and more convenient. The Digisight N770 is outfitted with built-in IR Laser Illuminator featuring three-step power adjustment. Complying with Class 1 laser safety, the laser IR Illuminator operates in the covert IR range (915 nm), invisible to the unaided human eye. The Weaver rail on the side of the body allows an auxiliary IR Flashlight to be attached. Basic control functions (switching on/off the riflescope and the IR Illuminator, activation of digital zoom) can be performed with the help of the included wireless remote control. The riflescope features a video output to conduct video recording to external devices without the use of additional adapters and camera or camcorders. If necessary output video signal standard can be changed from CCIR to EIA.
The Digisight N770 reticle (click value 13mm @ 100 m) is digitally inputted in the display and is permanently located in the image plane. The coordinate system (horizontal and vertical directions) helps remember zero reticle position for various distances or cartridges and move the reticle exactly to the required area. The riflescope uses by default a T-shaped reticle with illuminated dot in the centre, colour of which can be switched from red to green.
The Digisight N770 is resistant to bright light exposure and features excellent operational characteristics. The riflescope can be mounted on a wide range of hunting weapons including those of large calibers (shock resistance is guaranteed if cartridges with muzzle velocity not exceeding 6000 Joules are used). The riflescope operates on four rechargeable batteries but can also be powered with an external power supply. External power supplies such as EPS3 or EPS5 prolong riflescope’s operation time up to 9-20 hours.
