A 1534nm laser is eye safe at higher power levels than a 905nm laser, increasing its effective range for longer-distance targets. Additionally, the 1534nm laser offers the advantage of being undetectable by traditional night vision devices, enhancing its covert capabilities and is a preferred laser rangefinder wavelength for military systems.
The X4-FCS™ comes in Flat Dark Earth (FDE). Coming soon: Black or Olive Drab (OD) Green options. Note: The body is Type III Hard Anodize Finished - individual color shades may vary.
