Small size, ultra-low profile, no rezeroing

VIPER is the smallest, lightest, and most compact device in its class, measuring at only 254 grams (without battery). Its sophisticated low-profile clip-on design eliminates the need to remove your day sighting equipment since the device mounts directly in line with a standard daytime rifle scopes without the need of any tools. Most importantly, you do not need to re-zero the rifle every time you change the sight, which means point of impact always stays the same.

Black Hot displays warmer objects in black and cooler ones in white, which makes it a preferred mode among hunters and law enforcement.

Red hot

Red Hot is a recommended mode for prolonged observation. The red-black image minimizes blue light emissions from the display and reduces eyes strain from extended usage.
