How to Use Insta-Focus With Your Bushnell 4x30 Insta-Focus Compact Powerview Binocular

What if you had a device that let you see a crack on the opposite building of your house, the birds on the far-off nest, the cricketer clearly in a crowded stadium or your child's performance on the stage in a crowded hall? Bushnell offers a variety of binoculars that includes their expertise of more than 50 years of making quality optics. There are three main focusing systems: Center Focus, Insta-Focus and Individual Focus. InstaFocus binoculars have a central focusing lever between the barrels.

Instructions

Difficulty: Moderately Easy

1. Hold the binocular closer to your eyes and adjust the interpupillary distance.
2. Set the diopter to zero.
   
   
3. Set the Insta-Focus binocular by adjusting the central focusing lever between the barrels.
   
   
4. Cover the objective with the lens cover or your hand on the same side of the binocular that has the diopter setting. Generally, it is on the right side.
5. Focus on a distant object by using the Insta-Focus lever. Keep focusing until the image appears as sharp as possible.
6. Remove the cover from the objective lens on the diopter side. Cover the other objective lens and view the same object again.
7. Adjust the diopter setting ring carefully to view the clarity of the image.
8. Now you can view near or far distances by pressing the Insta-Focus lever.

Tips & Warnings

• Reset your binocular each time you view a new object.
• Make a note of the diopter setting appropriate for your eyes for future reference.
• Store your binocular in a cool, dry place.
• Handle with care.
• Use caution, as over-turning or forcing the diopter eyepiece can damage it or cause it to break away from the chassis.
• Do not expose your binocular to excessive moisture.
• Avoid banging or dropping.
• Looking directly at the sun with your binocular may be harmful to your eyes.
