Laser Performance 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. Under ideal
conditions, the Ranger can be expected to range a large reflective
object out to 1000 yards and deer-sized game out to 500 yards.
Using a tripod to steady the rangefinder can increase your ability
to range small targets at longer distances. If the Ranger 1000 is
used on a tripod, the reticle may appear tilted—depending on
tripod level.
Tripod Use for Ranging
• Light colors will usually reflect the laser pulse better than dark
ones. An exception would be snow, which can be difficult to range.
• Shiny, reflective surfaces will usually reflect the laser pulse better
than dull, textured surfaces. Animal hair will not reflect as well as a
hard surface.
• Ranging while under cloud cover can improve laser performance
compared to ranging while under bright sunny conditions.
• Solid objects, such as rock piles, will reflect the laser pulse better
than less dense items such as bushes.
• Flat surfaces perpendicular to the laser pulse will reflect better
than curved surfaces or surfaces angled in relation to laser pulse.
• Ranging over water can sometimes cause false reflections and
readings.
• At longer distances, larger objects will be easier to range than
small objects.
• The Ranger 1000’s laser pulse is emitted in an oval pattern
which is oriented vertically. If you are having trouble ranging an
object which is more wide than tall, try rotating Ranger 90 degrees
and range again.
• If you are having difficulty ranging an animal or object, try
ranging a different nearby object or use the Scan feature to pan
back and forth while watching for changes in range number.
