The Armasight Watchman IR Illuminator is a must-have for anyone in the field using night vision devices. Powered by VCSEL technology the Watchman IR Illuminator helps positively ID targets and track prey beyond 500 yards. This device features three brightness settings to aid visibility when there is low to no ambient light available and can focus as low as 3 degrees and out to a 14-degree field of view. The Watchman works great as a handheld unit however if the mission dictates you can mount it to your firearm or night vision device via the included 30mm ring. The push button tail cap can be swapped out for the provided tape switch if it is needed in a more tactical application. The body is constructed with aircraft-grade aluminum and is built to be shockproof with an IP67 waterproof rating. - Since IR illuminations are invisible to the naked eye a small red light located at the tail cap will light up when the unit is powered on. If you accidentally leave the illuminator on you won’t have to get a new battery. Simply recharge the 18650 with the included charging cord. - Features - Three Output Levels - Adjustable Field of View - Red Light Power-on Indicator - Weapon or Optic Mountable - Included: 30 mm Ring Extended Tape Switch Tail Cap 18650 Rechargeable Battery Charging Cable - Field of View: 3-14° - Wavelength: 850nm - IR Source: VCSEL - Optics: Fresnel - Battery Type: 1 x 18650 (Included) or 2 x CR123 (Not Included) - Mount: 30 mm Ring Mount (Included) - Switch: Tail Cap Button / Extended Tape Switch (Included) - High Output: 600mW - High Runtime: 5 Hours - Medium Output: 350mW - Medium Runtime: 8 Hours - Low Output: 175mW - Low Runtime: 15 Hours - Effective Distance on High Output: Up to 1000 Meters - Operating Temperature Range: -20-+60 Celsius - Body Material: 6061 T6 Aluminium - Finish: Type II Hard Anodized Black - Weight: 5.6 oz - Length: 5.5-6.5 in - Body Width: 30 mm - Bezel Diameter: 1.76 in - Waterproof: IP67 - Shockproof: Yes
