BINOCUlAR INSTRUCTIONS
Your Bushnell binocular is a precision instrument designed to provide many years of pleasurable
viewing. This portion of the booklet will help you achieve optimum performance by explaining how
you can adjust the binocular to your eyes, and how to care for this instrument. Read the instructions
carefully before using your binocular.
EYE ADJUSTMENTS (Figure 1)
How to Adjust For Distance Between Your Eyes
The distance between the eyes, called “interpupillary distance,” varies from
person to person. To achieve perfect alignment of lens to eye, follow these
simple steps.
1. Hold your binocular in the normal viewing position.
2. Grasp each barrel firmly. Move the barrels closer together or further apart
until you see a single circular field. Always re-set your binocular to this position before using.
How to Adjust For Individual Eye Strength
As individual eyesight varies from one person to another, most Bushnell binoculars have a diopter setting
feature which allows you to fine-tune the binocular to your vision. Follow the focusing instructions below
for your type of binocular.
