Nikon COOLSHOT 20 GII - 6x20 Laser Rangefinder Manual

Getting to know the Device

Key features

• Employs the First Target Priority algorithm that makes a flagstick easy to measure
• High-quality 6× finder with multilayer coating
• Automatic continuous measurement for up to 4 seconds if single measurement fails
• Press and hold down the PWR button to activate the continuous measurement function (up to approx. 8 seconds)
• Automatic power shut-off (approx. 8 sec. unoperated from standby screen)
• Rainproof — JIS/IEC protection class 4 (IPX4) equivalent (under Nikon's testing conditions)
• Invisible/Eyesafe EN/IEC Class 1M Laser

This product uses an invisible laser beam for measuring. It measures the time the laser beam takes to travel from the rangefinder to the target and back. Laser reflectivity and measurement results may vary according to climatic and environmental conditions, as well as the color, surface finish, size, shape and other characteristics of the target.

Measurement may be inaccurate or fail in the following cases:

• In snow, rain or fog
• Small or slender target
• Black or dark target
• Target has stepped surface
• Moving or vibrating target
• When measuring the surface of water
• Target measured through glass
• When the target is glass or a mirror
• When laser incidence to the target's reflective surface is oblique

Inserting/Replacing battery

Type of battery

3V CR2 lithium battery ×1

Inserting/Replacing battery

1. Open the battery-chamber cover.
   Rotate the battery-chamber cover counterclockwise and remove it.
2. Insert the battery.
   To replace the battery, take out the old battery before inserting a new one.
   Follow the battery insertion mark inside the battery chamber to insert the + and - ends of the battery in the correct orientation (insert so that the + end faces outward). If the battery is not inserted correctly, the Laser Rangefinder will not operate.
3. Attach the battery-chamber cover.
   Rotate the battery-chamber cover clockwise and secure it firmly. When attaching the battery-chamber cover, securely screw it all the way and check that it is secured.

• The battery-chamber cover may be difficult to rotate because this product uses a rubber seal to maintain its water resistance capabilities.

Measuring

1. Press the PWR button to turn on the power.

• If you do not operate the button for about 8 seconds, the power turns off automatically.
  

2. Aim at the target.
   Position the center of the target mark on the target.
   
3. Press the PWR button to measure.
   After measurement, the result is displayed for approx. 8 seconds, then power automatically turns off.
   Press the PWR button while the power is on to measure again.

Single measurement

Pressing the PWR button once starts single measurement, then displays the results.

• If measurement fails, measurement continues automatically for up to about 4 seconds until results are obtained. Measurement stops when it is successful, even within about 4 seconds.
  

Continuous measurement

Press and hold down the PWR button to start continuous measurement up to approx. 8 seconds. During measurement, the measured result is displayed consecutively while the laser irradiation mark is blinking. If you release your finger from the button, continuous measurement stops.

* If measurement fails, measurement continues automatically for up to about 4 seconds until results are obtained.

• When measuring a flagstick at a golf course
  Keep targeting the flagstick at the center of the target mark with the continuous measurement function to minimize the effects of hand shake.
