• 20-second continuous measuring function
The Nikon RifleHunter / Archer's Choice emits invisible, eyesafe, infrared energy
pulses that reflect off the selected target back to its optical receiver.
Sophisticated precision charge circuitry is used to instantaneously calculate
distances, by measuring the time it takes for each pulse to travel from the
rangefinder to the target and back. Laser reflectivity and measurement results
may vary according to climatic and environmental conditions, the colour, surface
finish, size, shape and other characteristics of the target.
The following factors ensure best range and accuracy:
• Nighttime use
• Cloudy weather
• Bright-coloured targets
• Targets with highly reflective surfaces
• Targets with shiny exteriors
• Large-size targets
• Shooting targets facing at 90 degrees
Measurement may result in inaccuracy or failure in the following cases:
• Slender or small target
• Target has diffusing reflective surface
• Target does not reflect the laser beam (glass, a mirror, etc.)
• Black target
• Target has varing depths
• In snow, rain or fog
• Target measured through glass
• Reflective surface measured from diagonal direction
• Moving target
• Obstacle moving in front of the target
• When targeting the surface of water
