OPTICAL DESIGN
The SPORT
® 850 features a Perma Focus monocular optical system for viewing your target. A liquid crystal
display (LCD) is mounted within the optical system and when activated, displays unit of measure, a reticle
for targeting, when the laser is actively firing, when a target has been acquired, and low battery indicators.
Inherent in the manufacturing process are small black spots that appear in the optical system. These are a
natural characteristic of the LCD and cannot be fully eliminated in the manufacturing process. They do not
affect the distancing performance of the unit. A summary of these features is presented below.
UNIT OF MEASURE OPTIONS
The Sport
® 850 can be used to measure distances in yards or meters. The unit of measure indicators are
located in the lower right portion of the LCD. To select between yards and meters, the unit should be off.
While looking through the eyepiece, press and hold the POWER button down for approximately 5 seconds.
During this time all liquid crystal segments and icons will be displayed. As you continue to depress the power
button, the display will toggle back and forth between Yards and Meters. Once the unit of measure desired
is displayed, simply release the power button. The device will return to the last unit of measure setting used
each time the unit is turned on.
RETICLE FOR TARGETING OBJECTS
Place the aiming circle (located in the center of the field of view) upon a target at least 5 yards away, depress
and hold the power button down until the range reading is displayed near the bottom of the in-view display.
ACTIVE LASER
Crosshairs surrounding the aiming circle indicate that the laser is being transmitted. Once a range has been
acquired, you can release the power button. The crosshairs surrounding the circle will disappear once the
power button has been released (i.e. the laser is no longer being transmitted).
