Impact Laser Rangefinder (LRF100)
Simply put, with the high-performing Impact 850 you don't have an excuse to head afield without a laser rangefinder. Accurately ranges reflective targets to 850 yards, providing critical distance readings hunters and shooters can rely on. Range targets down to 10 yards when things get up close and personal. 6X magnification brings subjects in for a closer look and more accurate ranging. Fully multi-coated optics enhance light transmission for optimal performance in low-light settings. Provides angle-compensated HCD (Horizontal Component Distance) and LOS (Line of Sight) readings to match user preference. Can be set to read in yards or meters. The black LCD display boldly stands off against subjects during the moment of truth – and a fast readout ensures you get the range in time to capitalize on the opportunity. Runs on a single, long-lasting, easy-to-find, CR2 battery.
HCD (Horizontal Component Distance) Mode
The Impact 850’s HCD range display is intended to be the primary mode—used for most rifle and archery shooting conditions. The yardage number displayed is the critical horizontal component distance.
Use the HCD range mode in the following situations:
• Rifle shooting on level ground at any range.
• Rifle shooting out to ranges of 800 yards with mild slopes (less than 15 degrees).
• Rifle shooting out to ranges of 400 yards with moderate slopes (15 to 30 degrees).
• For all archery shooting.
The displayed HCD yardage number is corrected for shot angle and needs no extra user input; shooters simply use the appropriate level ground bullet drop and wind adjustment for the range displayed and shoot. Archers use the appropriate level ground sight pin for the range displayed and shoot.
LOS (Line of Sight) Mode
The Impact 850’s 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 ballistic programs and who are shooting at distances beyond 500 yards and with slopes greater than 15 degrees. Most shooters and archers will not need the LOS mode.
The range number displayed in LOS mode is the actual line of sight range with no ballistic correction for slope. Most of the commonly used ballistic devices can provide independent slope correction for bullet drop data and require actual line of sight range input. Using the LOS range when calculating bullet wind drifts under these steep slope/long range conditions will provide a higher degree of accuracy than using the HCD range.
When in LOS mode, an additional number is displayed below the yardage number. This number is slope shown in degrees.
Scan Feature
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 the laser back and forth, watching for changes in the yardage number as the crosshairs move across the target object. A blinking 'S' display indicates Scan Ranging is activated.
