Page 9: Mounting The Tripod
MOUNTING THE TRIPOD All Firefield Siege monoculars include a tripod that attaches to the built-in tripod mount. The built-in tripod mount also works with most aftermarket tripods and window mounts. The built-in tripod mount can be used with any tripod or window mount that uses a standard 1/4-20 UNC tripod screw. - Page 10 USING THE RANGEFINDING RETICLE The Firefield Siege 10x50R Tactical Monocular uses a mil reticle. Mil stands for millra- dian. A millradian is 1/6283.2th of a circle, or 3.438 MOA. The millradian represents 1 unit at 1000 yards. To simplify, a target that is one yard tall at 1000 yards would measure 1 millradian.
