Lanyard
The lanyard provides a secure way
to carry your rangefinder.
MAINTENANCE
• Use a lens brush to remove dust or grit from lenses.
• Use a clean lens cloth or tissue to remove smudges or
smears from lenses.
• Store rangefinder in a dry location away from
direct sunlight.
Loop lanyard through
attachment sockets.
RANGEFINDING TIPS
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.
• Light colors will usually reflect better than dark ones.
• Be aware that snow, rain, and fog will have adverse
effects on ranging ability.
• Shiny, reflective surfaces will usually reflect better than
dull, textured surfaces. Animal hair will not reflect as
well as a hard surface.
• Ranging under cloud cover can improve laser
performance compared to bright sunny conditions.
• The position of the sun compared to the rangefinder
and/or range target will greatly affect performance.
• Solid objects, such as a rock, will reflect better
than bushes.
• Flat surfaces perpendicular to the laser pulse will
reflect better than curved surfaces or surfaces angled in
relation to laser pulse.
