The BOLT Series was designed from the ground up for optimal use on bolt action rifles and other platforms that demand flexible mounting options with increased eye relief. The image from an InfiRay 50Hz 12 micron Micro II core is displayed on a crystal clear HD display. These components and InfiRay's proprietary MATRIX III algorithm create an image technically and visually superior to optics with similar specifications. The BOLT comes standard with 16GB of internal memory for storing 20,000 images or 24 hours of video. Captured videos and images can be easily transferred to your smartphone at lightning speed via app. The WiFi mode also allows for up to four connections to the BOLT simultaneously allowing multiple viewers to see the BOLT's thermal image in real time. Audio can also be recorded in the app via your smartphone microphone while connected to the app. The BOLT supports charging the internal batteries through a USB-C connector while in operation so you are never stuck with a dead battery. 8 hours of battery run time expandable to 10+ hours with optional 18500/18650 battery (not included).
