Designed to quickly turn your day scope into a night scope, this front-attachment monocular enhances your ability to hunt predators or track targets in no-light situations or in dense environments. It also serves as a laser rangefinder to deliver the precision you need to make the shot at distances of up to 1000 meters.

Available in either a 35mm or 50mm objective lens size, these LRF monocular attachments are designed to seamlessly integrate with a broad spectrum of riflescopes and can support scopes of up to 10x magnification. They have a 640×512 12 µm <18mK sensor for impressive thermal sensitivity and detection distances of up to 1800 meters for the 35mm model and 2600 meters for 50mm model. The device also uses a state-of-the-art image processing system that quiets environmental noise for enhanced target clarity. They also use advanced sub-pixel zeroing technology for ultra-fine reticle adjustments that keep errors to under 0.9cm at 100 meters. A Bluetooth remote control eliminates the needs for awkward reaches and allows for easy adjustments without compromising stability.

Each device has an OLED display that generates vivid images with excellent contrast in your choice of six color palettes black hot, white hot, green, iron hot, red hot or sepia. It also offers recoil-activation automatic video recording, 32GB of internal memory and Wi-Fi functionality for live streaming to a user’s own device.

In addition to being waterproof and shockproof, the 640 thermal clip-on is made of magnesium alloy that adds robustness without being burdensome. To ensure reliability for long days in the field, the device features a quick-release cover for effortless battery changes and is equipped with two batteries in total to deliver a substantial 15-hour runtime when used together.
