Congratulations on selecting your new Carson binoculars!

With reasonable care, your binoculars will provide you with years of enjoyment.

In order to achieve optimum performance, please read the instructions

carefully on the proper use and care of your binoculars.

Instructions for Care

Like any ﬁne optical instrument, your binoculars should be

given sensible care. Keep the lens covers (not included with

some models) on the lenses when binoculars are not in use.

Do not drop or violently jar your binoculars. This may cause the internal

optical components of your binoculars to become misaligned resulting

in a double image when looking through them. Non-waterproof models

should not be exposed to excessive moisture.

Cleaning

Cleaning must be done safely and carefully to avoid scratching the lenses and permanently damaging

your binoculars. Safe cleaning can be accomplished using a Carson LensPen™ lens cleaning device.

If you do not own a Carson ™, please follow the procedure below:LensPen

1. Blow away any dust or debris on the lens (or use a soft lens brush).

2. To remove dirt, grease or ﬁngerprints, clean with a soft cotton cloth rubbing in a circular motion.

Use of a coarse cloth or unnecessary rubbing may scratch the lens surface and eventually cause

permanent damage.

3. For a more thorough cleaning, photographic type lens cleaning ﬂuid may be used. Always apply

the ﬂuid to the cleaning cloth, never directly on the lens.

4. IMPORTANT: Never attempt to clean your binoculars internally or try to take it apart.

Basic Binocular Terminology

Binoculars are commonly identiﬁed using two sets of numbers. The most common size is 8x21mm.

The “8” is the magniﬁcation, and “21” is the diameter of the objective lens in millimeters.

Magniﬁcation: Typically binoculars range from 5x to 12x power. A 5x binocular means that the image

you see through the binocular is 5 times larger than it would be when viewed with the naked eye.

There are larger power binoculars available, and most higher power binoculars are usually the variable

type, also known as zoom binoculars. A 20x – 80x zoom binocular, for instance, has a magniﬁcation range

from 20to 80 power.

Objective lens: The objective lens (front lens) diameter is listed in millimeters. The larger the lens, the

more light can enter the binocular and the brighter the image will be. However, binoculars with smaller

lenses are more compact and portable.

Field-of-View: (also known as FOV) is the total width of the viewing area through your binoculars from

left to right. It is often measured in feet at 1,000 yards. For instance, if you see “358 ft @ 1000 yds”,

that means an object that is 358’ wide and a thousand yards away will take up the entire viewing area

of the binocular image you see. Sometimes this measurement is listed in degrees and is referred to as

Angle of View, i.e. 8°

. To convert to feet, multiply the number of degrees by 52.5 and you will get the FOV.

Example: If Angle of View is 8°, Field of View is 8 x 52.5 = 420’ @ 1,000 yds.

Types of Binoculars

Fixed focus zoom and binoculars are alternatives to standard binoculars, which traditionally

offer magniﬁcation in one set power only, with a wheel or knob used to engage the focus mechanism.

Fixed focus binoculars cannot be adjusted and are usually ﬁxed at an average distance for use in

concerts, opera, or any situation in which variable focusing on objects is not required.
