RANGER 1800 ® LASER RANGEFINDER Mode Selection Set and Save Mode Selections in 3 Steps Your Ranger 1800 is factory set to the angle compensating HCD mode, yards, and medium brightness. For most users, these are the preferred settings. 1. Choose between the HCD and LOS Modes. After activating the Mode Selection, press the Measure button to toggle between the HCD and LOS displays. Press the Menu button to save your desired choice and move to the Yards/Meters selection screen.
RANGER 1800 ® LASER RANGEFINDER 3. Choose the Brightness Setting. The Ranger® 1800 provides three illumination settings. Press the Measure button to toggle through the three Brightness settings. Press the Menu button to save your desired setting and move back to HCD/LOS selection screen. Ranging With the Ranger® 1800 powered up, position the crosshair on the target object and press and release the Measure button to get the distance measurement.
RANGER 1800 ® LASER RANGEFINDER Ranging Mode Explanations Using the HCD Mode The Ranger 1800 provides two range modes: HCD (Horizontal Component Distance) and LOS (Line of Sight). Both modes offer a Scan feature. Use the HCD range mode in the following situations: ® HCD Mode The Ranger® 1800 HCD range display is intended to be the primary mode—used for most all rifle and archery shooting conditions. The yardage number displayed is the critical horizontal component distance.
RANGER 1800 ® LASER RANGEFINDER LOS Mode LOS Mode – Using the Incline Number The Ranger 1800 LOS (Line of Sight) mode is intended for rifle shooters who are using slope correcting ballistic drop data cards, ballistic cell phone applications, or other devices with ballistic programs and who are shooting at distances beyond 500 yards and with slopes greater than 15 degrees. When in LOS mode, an additional number is displayed below the yardage number. This number is slope shown in degrees.
RANGER 1800 ® LASER RANGEFINDER Scan Feature Tripod Use for Ranging The Scan feature can be used to range moving targets or help range smaller targets on uniform backgrounds in either HCD or LOS modes. Once powered up, press and hold the Measure button and scan laser back and forth, watching for changes in the yardage number as crosshairs move across the target object. A blinking “S” display indicates Scan Ranging is activated.
RANGER 1800 ® LASER RANGEFINDER Rangefinding Tips FCC Requirements Laser rangefinders work by emitting a brief pulse of light aimed at a target object. Distance is determined by the amount of time taken for the light to emit and return to the laser’s internal receiver. A laser’s ability to read range can be affected by many things—mostly relating to the target objects.
RANGER 1800 ® LASER RANGEFINDER Laser Safety and Precautions Do not stare into beam or view directly without laser eye protection. Staring continuously into beam for prolonged periods of time could cause harm to your eyes. If used properly, this device is safe for your eyes and laser eye protection is not needed. • Use the correct battery (CR2) and proper battery orientation. • Do not look at sun. • Do not activate Menu or Measure buttons while aiming at eye or looking into objective lens.
