To hold the binoculars properly it’s better to buy a lighter binocular. Easier to hold better the view.

Exit Pupil:

This is the size of the image at the focusing point of the binocular. It is computed by dividing the objective size by the magnification. The exit pupil of an 8×40 binocular is 5mm (40/8). A larger exit pupil means a brighter image. Binoculars over 3mm are considered good for daytime birding and anything over 7mm is a waste.

Eye relief:

Eye relief is the distance from the rear eyepiece lens to where the image is formed. Eyeglass wearers should look for binoculars with at least 15mm of eye-relief and have eye-cups that can be folded down. This will allow them to enjoy bird-watching.

Close Focus:

Good birding binoculars should have a close focus of 10 feet or less otherwise you may find yourself walking backwards to try and see something. How close a binocular focuses depends on how it is made rather than on its power.

Body Design:

There are two basic types. i) Porro prism Binoculars and, ii) Roof prism binoculars. Roof prisms are lighter, rugged, easier to maintain and usually waterproof. Porro prism binoculars are cheaper, Optical quality is not markedly different though roof prisms being more expensive usually have better coating.

Binoculars are what makes bird-watching pleasurable - so invest in the best that you can afford, they are sure to give you years of memorable moments.

Finding the bird:
Looking with your naked eyes, find a bright leaf in a distant tree, or a certain spot on a distant building, and lock you eyes onto it. Now, without removing your eyes from that spot, bring your binoculars up to your eyes and into alignment with your view.With practice you’ll find that locking your eyes in place and bringing the binoculars into alignment really works. This will make it easier for you to find birds with your binoculars, even if a bird is moving.

Roughly all binoculars have a “diopter adjustment” which allows you to set the two sides of your binoculars to match the differences between your eyes. You can find it on the right side, you can see zero marked between a plus and a minus sign. Make sure its at zero before you start this adjustment.
• Place the lens cap or the palm of your right hand over the right objective lens (or the left hand over the left lens if that’s the side with the diopter adjustment) and focus on the object using the central focus. Make the focus as crisp as you can. Try to do this without closing your other eye.

• Switch your hand or lens cap to cover the other objective lens, and now make the same object as crisp as you can using the diopter adjustment.

• Switch your hand or lens cap again to double check how good the focus is-if adjustments are necessary, use the central focus.

• Then switch your hand or lens cap one last time, and fine tune the diopter adjustment.

• Now look through both lenses, and make sure the object is well-focused. Focus on something closer, and something farther away, using the central focus, to make sure the binoculars are set right. Then notice exactly where the diopter adjustment is set. This is where it should stay whenever you use your binoculars. (If you sometimes wear different glasses or contact lenses, your diopter adjustment setting may be different in those situations.) You should always use the center focus now.

Once in a while you should retest the diopter setting in case your vision has changed.

Binoculars are most often used by people who travel. Binoculars are mainly helpful in journey travel, such as traveling to national parks or safaris, where the explorer might want to view wildlife. Travel binoculars are usually lighter and more solid than usual binoculars. They effortlessly fit in a carry on bag, and some are tiny enough to fit in a pouch.

Machinery of Travel Binoculars

It’s always good to know the working of binocular before you choose.

Prism

With the help of prism you see the images right-side-up when looking through the binoculars. Travel binoculars usually have roof prisms, which are present inside the optical tube of the binoculars. It reduces the space and makes it great to travel.

Lens Coating

Glass surfaces are coated that touch the outside air. The coating helps transmit the light. Its better to look for binoculars which are fully coated. Multicoated binoculars reduces glare.

Magnification and Objective Lenses

Magnification is the power of the binoculars. Magnification is usually confirmed in two numbers, such as 8 x 25. The first number means how much the binoculars magnify an object. An 8x magnification means that the object looks eight times closer than natural eyesight. The second number is the objective lens diameter. The lesser the diameter, the more compact your binoculars are for travel. However, the larger the diameter, the more light you will have entering your binoculars. The objective lens is the lens that faces the object.

Exit Pupil

The exit pupil is the lens by your eye. If you hold the binoculars at arms length, you will see a small spot of light through the eyepieces. This is the exit pupil.

Field of View

You will have a limited field of view, which is the area you can see when looking through your binoculars. This area is measured in degrees. If you are going to be watching moving objects, look for a large field of view.
