How to Use Your Binocular Properly | Trolling Power Solution
The primary function of a binocular is to provide sharp, bright and color true images of the object being viewed.
This can only be achieved when the left and right optical systems are accurately focused. Adjusting your binoculars may seem like an easy task, but this is not the easy especially for first-time users.
You would need to make allowances for the viewing distance and correct any difference that may exist in both eyes.
Properly adjusting your binoculars requires key steps that will help you get the most out of your hunting binoculars. These steps are discussed in the rest of this article.
Before using your binoculars, it is important that the eyepieces and objective lenses are clean. Clean them with a suitable fabric to remove any fingerprints or dust. This is an essential step that should not be overlooked because fingerprints on the lens can cause up to 20% loss of light transmission.
Cleaning tips: Use a special optical brush to get rid of dust and other residues. Then use a cleaning cloth to take care of the fingerprints.
Step 2: Adjust The Interpupillary Spacing
Once done cleaning the outer faces of the lenses and eyepieces, the next step is the adjustment of the inter-pupillary spacing.
This is also an essential step if you want perfect views from your binoculars. Your eye must be perfectly aligned with the lenses. Poor inter-pupillary adjustment will severely degrade vision and shadows will appear at the edges of images.
Step 3: Adjust The Sharpness
To see the object or animal being observed clearly and firmly, rotate the central wheel to the right or left until the clearest image is obtained.
Attention: The more the magnification your binoculars offer, the smaller the field of view. There might also be a degradation of sharpness around the edges of images with large magnification devices. So the general rule is, the smaller the magnification, the larger the field of view.
Step 4: Correcting The Difference in Vision Between The Two Eyes
To correct the difference in vision between the two eyes:
Close your right eye on and focus on the object at about 50 meters with the center wheel. Once the object is sharp, close the other eye and repeat the operation by focusing this time with the diopter correction (a ring near the right eyepiece).
Once this is done, the difference is corrected. There is no need to adjust this setting in the future.
5. Adjustment for Eyeglass Wearers
If you wear glasses, this step will allow you to obtain a clear image. The binoculars with retractable eyecups are comfortable for eyeglass wearers.
For non-glass wearers, pull out the eyecups as far as possible by turning them. If you wear eyeglasses, position the eyelets in the screwed position against the body of the binoculars.
