BASIC OPERATION
• While looking through the laser rangefinder, press and release the Power/Fire button to activate the display.
• If the display appears blurry, rotate the rubber eyecup/diopter adjustment in either direction until the display is sharp for
your vision.
• Placing the aiming circle (located in the center of the display) on a target at least 5-6 yards away, depress and hold the Fire
button down until the range reading is displayed below the aiming circle.
• Once a range has been acquired, you can release the Fire button. The four "crosshairs" just outside the aiming circle will go
out, indicating the laser is no longer being transmitted. The display will remain on and display the last distance measurement
for about 15 seconds, until the display automatically switches off to extend battery life.
• You can press the Fire button again at any time to check the range to a new target. To re-fire, press the button again.
• To scan the laser across an area and get continuously updated range readings, simply continue to hold the Fire button
down and sweep the rangefinder over multiple targets. The crosshairs outside the aiming circle will flash to indicate scan
operation.
DISPLAY INDICATORS/ICONS
The Bone Collector 850 rangefinder's display incorporates the following
illuminated indicators:
• Battery Level Indicator (1)
• Aiming Circle/Dot (2)
• Active/Scan Laser Indicator (3)
• Standard "Line of Sight" Distance (4)
• Distance Units Indicators (5): Y=Yards, M=Meters
• Angle Indicator-incline in degrees (6)
• True Horizontal Distance (angle compensated range) (7a) / FEEt
(Feet) Distance Units Indicator (during setup only) (7b)
SELECTING UNIT OR MEASURE (YARDS/METERS/FEET)
The Bone Collector laser rangefinder can be used to measure distances
in yards (default setting), meters or feet. The unit of measure indicators
for Yards or Meters (5) is located to the right of the Standard "Line of
Sight" Distance (4). If "Y" or "M" (5) are not lit when ranging, distances
are in Feet.
To select a different unit of measure, start with the rangefinder powered off. Press and continue to hold the Fire button."Y", "M"
or "FEEt" will begin flashing, with the display slowly cycling through these 3 unit options (5,7b). Release the Fire button when
your desired display units are flashing. To select a different unit of measure, repeat this process.
AUTOMATIC SCAN
To use the Automatic SCAN feature, simply press and hold the Fire button, then move the rangefinder from object to object
while keeping the Fire button depressed. Automatic SCAN will cause the standard line of sight distance readout (4) to be
continuously updated as multiple objects are targeted. The Active/Scan indicator lines (3) flash while scanning.
ANGLE RANGE COMPENSATION (ARC)
The Bone Collector 850 Laser Rangefinder with ARC™ was especially designed with hunters in mind. Your rangefinder features
a built-in inclinometer that solves a problem hunters have been faced with for years. Bow and rifle hunters have struggled with
extreme uphill and downhill angles because of how these angles alter true horizontal distance to your target. The ARC™ solution:
an integrated inclinometer provides angular data to a processor chip when targeting objects that are either uphill or downhill.
This data is then combined with internal algorithmic formulas.
When the Fire button is released, the Bone Collector 850 laser rangefinder's display will show you the standard "line of sight"
distance near the center of the display (4), along with the angle of incline in degrees (-/+ 70
display (6). The true horizontal distance (angle compensated range) is also shown, near the bottom of the display (7a). The True
