BINOCULAR SPECIFICATION & TERMINOLOGY
01 | Magnification
The binocular magnification specification is the first number in the binocular description. e.g. a 10x42 binocular has a magnification power of 10x. That is to say, the viewed image will be 10x larger than with the naked eye.
While a higher magnification will make the image larger and easier to view it will also reduce the field of view and make any movement of the binoculars more exaggerated.
Typically an 8 or 10x magnification power is the preferred choice, but 12x magnification is also available in some models.
02 | Objective Lens
The objective lenses are at the front end of the binocular. The width of the objective lens relates to the second number in the binoculars description. e.g. a 10x42 binocular has a pair of objective lenses that each measure 42mm in diameter.
Larger objective lenses give better light transmission and allow for a brighter picture. A larger objective lens will allow the binoculars to be used in lower light conditions.
03 | Field of View (FOV)
The width of the binocular’s view. A larger FOV allows for a wider image to be seen.
This can be measured in terms of angle (degrees), or by a set distance. e.g. the FOV of the Frontier ED X 8x42 is 142m wide when looking at an image 1000m away. This is equivalent to 426ft wide when looking at an image 1000yds away.

04 | Exit Pupil
The diameter of the viewing image when the eye is positioned at the correct eye relief. This is calculated by dividing the objective lens diameter by the binocular magnification. e.g. for a 10x42 binocular we divide the objective lens diameter of 42mm by the magnification power of 10 to get 4.2mm.
06 | Eye Relief
The correct distance for the pupil to be located from the ocular lens. When at this distance the best viewing experience will be achieved. All Hawke binoculars are fitted with adjustable twist-up eye cups to help gain the correct eye relief distance and comfortable viewing experience. (see page 9)
05 | Interpupillary Distance
The distance between the two ocular lenses. This is measured from the middle of one lens to the other. The interpupillary distance has a range, as the distance will change depending how open or closed
07 | Close Focus
The closest possible distance that the binoculars can be focused at. Binoculars with an ability to focus at close range allow for better viewing of nearby objects such as insects.
the binoculars hinge is set.

GLASS QUALITY & COATINGS
01 | Extra-low Dispersion (ED) Lenses
ED lenses are the most effective way to improve image quality and stop colour fringing (chromatic aberration). ED glass allows for better concentration and direction of light wavelengths, which give a significantly sharper image and improved contrast of colours and light.
02 | Apochromatic (APO) Lenses
An APO lens is built from multiple elements to more tightly control multiple colour wavelengths into one. This fur ther reduces chromatic aberration and enhances image quality.
03 | Fully Multi-Coated (FMC) Lens Coating
There are many lenses within a binoculars optical system. Hawke’s FMC lenses ensure that both sides of every lens have multiple layers of coating which assist with light transmission and help produce brighter images with improved contrast.
04 | BAK-4 Roof Prism
BAK-4 is a type of glass used within the prism, which is a system of glass elements inside the binocular that ensure the viewed image is the correct orientation after being magnified. A roof prism is a more compact and sharper version of older traditional Porro prisms.
05 | Phase Corrected Coating
The light traveling through a binocular prism is reflected several times and as such can lose its “phase”, meaning that colours can appear overlapping and produce colour fringing, also known as chromatic aberration. A phase correction coating helps to stop chromatic aberration.
06 | Silver Mirror Coating
A silver mirror coating can be applied to elements within the prism and increase reflection. This also improves brightness and colour reproduction. The silver coatings have a reflectivity of 95% to 98%.
07 | Dielectric Coating
Dielectric Coating of the prisms improves internal reflection even more than a silver mirror coating. This maximises the quality of visible light and produces clear, high­contrast images, similar to those seen by the naked eye.
08 | Water Repellent Coating
Water repellent coatings significantly improve optical performance in wet weather conditions. The extra lens coating encourages the water droplets to “bead” and form into smaller drops that are easier to clean and will more actively run off the glass lens.
09 | Strehl Ratio Tested
Meeting the Strehl Ratio optical parameter ensures the image is crisp with no, or less, haziness. This produces a feeling of not actually looking through lenses.

PARTS & MECHANICAL FEATURES
01 | Dioptre
Each binocular is equipped with an adjustable dioptre which is used to correct any imbalance in eye strength. Typically the dioptre adjuster is positioned on the right hand eyepiece.
02 | Focus Wheel
The focus wheel can be easily rotated to change the focal distance of the binoculars. All Hawke binoculars feature a central focus wheel which accurately guides and adjusts the internal lenses while keeping them protected from outside elements and dirt.
03 | Hinge Design
All Hawke models are adjustable at a central hinge.
04 | Tripod Attachment
All Hawke full-sized binoculars have a tripod fitting with a standard tripod thread (1/4-20 UNC). This allows for positioning and solid mounting to keep the binoculars still when in use
05 | Twist-Up Eye Cups.
With multiple height settings, the twist-up eye cups can be set to ensure the best eye relief for your use. Eyeglasses users often leave the twist-up eye cups in the downward position, while non-eyeglasses users rotate the twist-up mechanism upright. The Frontier models have the added feature of replaceable twist-up eye cups with position stops, allowing for the eye cups to be replaced easily.
06 | Strap Loops
All Hawke binoculars are engineered with a low-profile strap loop that provides a secure attachment point for your beloved optics.
07 | Nitrogen Purged
Hawke binoculars are filled with nitrogen gas to ensure that no condensation or humidity is held within the optical system which can otherwise haze and cloud the optical view when moving between warm and cold conditions. The nitrogen gas is sealed into the binoculars during manufacture to ensure no moisture can infringe the optics.
08 | Chassis
Designed from conception to offer the best performance available, models include lightweight magnesium alloy body or polycarbonate chassis and soft touch rubbers.

SPOTTING SCOPE SPECIFICATION & TERMINOLOGY
01 | Magnification
Spotting scope magnifications are often variable as the zoom eyepiece allows the user to change from low to high magnification. The magnification range is denoted by the first two numbers in the spotting scope’s description. e.g. a 20-60x85 spotting scope has a magnification power of 20 to 60x. That’s to say the viewed image will be 20 to 60x larger than with the naked eye, depending on the magnification setting.
Whilst a higher magnification will make the image larger and easier to view it will also reduce the field of view and make any movement and tracking of animals more difficult.
02 | Objective Lens
The objective lens is the front lens of the spotting scope. The width of the objective lens relates to the last number in the spotting scope’s description. e.g. a 20-60x85 spotting scope has an objective lens that measures 85mm in diameter.
Larger objective lenses give better light transmission and allow for a brighter picture. A larger objective lens will allow the spotting scope to be used in lower light conditions.
03 | Field of View (FOV)
The width of the spotting scope’s view. A larger FOV allows for a wider image to be seen.
This can be measured in terms of angle (degrees), or by a set distance. e.g. the FOV of a 20-60x85 spotting scope could be 35 – 17.5m wide when looking at an image 1000m away. The view is 35m wide when on the lowest 20x magnification and is 17.5m wide when on the highest 60x magnification. This is also equivalent to 105 – 52.5ft wide when looking at an image 1000yds away.

PARTS & MECHANICAL FEATURES
01 | Sunshade
When using the scope in bright conditions, or when the sun is low and shining into the spotting scope’s lens, the built-in extendable sunshade can be used to prevent glare.
02 | Nitrogen Purged
Hawke spotting scopes are filled with nitrogen gas to ensure that no condensation or humidity is held within the optical system which can otherwise haze and cloud the optical view when moving between warm and cold conditions. The nitrogen gas is sealed into the spotting scope during manufacture to ensure no moisture can infringe the optics.
03 | Focus Wheel
The focus wheel can be easily rotated to change the focal distance of the spotting scope. All Hawke spotting scopes are designed to accurately guide and adjust the internal lenses while keeping them protected from outside elements and dirt.
• Dual Focus Knob – a dual Focus Knob has
two sensitivities for adjustment; coarse and fine. The coarse adjustment is fast changing for quick settings, then the fine adjustment allows for more accurate and precise focus correction.
• Focus Knob – a single Focus Knob that
allows for adjustment from near to far focal distance.
04 | Tripod Attachment
All Hawke spotting scopes have a tripod fitting with a standard tripod thread (1/4-20 UNC). This allows for positioning and solid mounting to keep the spotting scope still when in use. A rotating tripod band is available on some models to allow body rotation and alternative scope orientation.
05 | Eye Cup Adjustment
The eye cup can be set to ensure the best
eye relief for your use. Eyeglasses users
often leave the eye cup adjustment in the
downward position, while non-eyeglasses
users keep the eye cup upright.
• Twist-Up – with 3 levels of adjustment the eye cup can be twisted into position to suit.
• Folding – the rubber eye cup can be folded down to suit eyeglasses wearers.
06 | Digi-scoping
Digi-scoping is the art of using the spotting scope’s optical performance to enhance your camera and capture photos at a much higher magnification. Digi-scope adaptors are available to attach a camera to the spotting scope.
