* Waterproof models

This Nikon Laser Rangefinder is waterproof, and will suffer no damage to the optical system nor observation if

submerged or dropped in water to a maximum depth of 1 meter for up to 10 minutes.

The Nikon Laser Rangefinder offers the following advantages:

• Can be used in conditions of high humidity, dust and rain without risk of damage to internal functions.

• Nitrogen-filled design makes it resistant to condensation and mold.

Observe the following when using the Nikon Laser Rangefinder:

• The unit is not a sealed structure, so it should not be operated nor held in running water.

• If any moisture is found on movable parts of this equipment, stop using it and wipe it off.

** The battery chamber is water resistant, not waterproof. Water may enter the device if the Rangefinder is submerged in

water. If water enters the battery chamber, wipe out any moisture and allow time for the chamber to dry.
