Tripod Use For Ranging
Using a tripod to steady the rangefinder will increase
your ability to range small targets at longer distances. If
the Viper
®
HD 3000 is used on a tripod, the reticle may
appear tilted depending on tripod level.

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.
• Snow, rain, fog, and air quality will have adverse effects
on ranging ability.
• Dull or textured surfaces will not reflect as well as a
hard, shiny surface.
• Ranging under cloud cover can improve laser
performance compared to bright sunny conditions.
• Solid objects, such as a rock, will reflect better
than bushes.
• Flat surfaces perpendicular to the laser will reflect
better than curved surfaces or surfaces angled in relation
to laser.
• Ranging over water can sometimes cause false
reflections and readings.
• At longer distances, large objects will be easier to range
than small objects.
• Using a tripod to steady the Viper
®
HD 3000 will
greatly increase your ability to range small targets at
longer distances.
• If you have difficulty ranging an animal or object, try
ranging a different nearby object. Use the Scan
Feature to pan back and forth while watching for
changes in range number, or switch to ELR Mode.
