Vanguard Endeavor ED IV 10x42 WP binoculars

The history of Vanguard Endeavor ED IV binoculars is a journey from good to better, built on the success of the previous two generations. The fourth generation Vanguard Endeavor ED is a symphony of technology and design. Driven by the ambitious goal of creating the most innovative products in the world, the company's engineers made sure to introduce all the latest innovations in the field of optical instrument construction. While the designers once again created a masterpiece of ergonomics and proportions.

The use of low-dispersion ED glass from the Japanese manufacturer HOYA in lenses, and SK15 glass inverting prisms puts the Vanguard Endeavor ED IV 10x42 WP on a par with optical devices of the highest class. Durable magnesium body, diopter adjustment with a lock in the center position, dielectric and phase-correcting prism coatings, MultyGuard proprietary anti-reflection and hydrophobic lens coatings - this is an incomplete list of what is the standard for this series of binoculars, and what can not always be found in competitors in this price category.

Of particular note is the double-hinged open bridge hull design. This solution certainly increases the rigidity of the entire body. But that's not the point. You only need to pick up open-bridge binoculars once to experience the convenience of its use and the advantages of this design.

If you are driven by a passion for nature and adventure, if you are a keen hunter or an experienced traveler, regardless of your hobbies, Vanguard Endeavor ED IV 10x42 WP binoculars will become an integral part of your hobby.

HOYA ED Glass . The lenses of this binoculars are equipped with low-dispersion ED glass HOYA made in Japan. HOYA has been known for over 70 years as a manufacturer of exceptional quality optical glasses. The refractive index of HOYA low-dispersion glass is extremely small and does not depend on the wavelength of light. All wavelengths of the light spectrum are refracted through the same angle, thereby achieving minimal light scattering and eliminating chromatic aberration (color distortion).

Advanced MultiGuard® Coatings . The most technologically advanced seven-layer anti-reflective coating applied to each optical surface provides a high level of light transmission of the optical system and unsurpassed natural color reproduction. Additionally, a super-strong hydrophobic membrane is applied to the outer surface of the lenses and eyepieces, which protects against scratches, prevents the accumulation of water on the lenses and oil contamination.

SK15 Prism . Significant light losses occur in an inverting prism system, regardless of its design. The use of SK15 optical glass with a high refractive index and a high Abbe number will minimize light loss, largely avoiding unwanted internal reflection and light scattering in the prisms. SK15 glass prisms are used exclusively in premium binoculars by only a few manufacturers.

Phase Correction. The use of a multi-layer phase-correcting prism coating is today the standard for high-quality binoculars with a wrapping prism Roof design. During passage through such a prism system, light is reflected from opposite sides of the prism, polarized, and a shift of half the phase of the light wave occurs, resulting in a loss of contrast. The thinnest phase-correcting coating applied to one of the surfaces of the prism aligns the phases, providing high resolution and image contrast.

Dielectric Coating. The dielectric multi-layer highly reflective coating is used exclusively in optical devices with an enveloping prism structure Roof of the Schmidt-Pechan system. One of the surfaces of the Roof prism system does not have total internal reflection. It is on this surface that a reflective coating must be applied. The dielectric coating, unlike aluminum or silver sputtering, has almost 100% reflective properties, provides high light transmission, natural color reproduction, and is used exclusively in premium optics.

Waterproof & fogproof. These binoculars are IPX7 water resistant and are protected from internal condensation. The case is sealed with a rubber sealing O-ring, which allows the binoculars to stay under water at a depth of 1 meter for up to 30 minutes without letting moisture in. From the internal cavities of the housing, air and water vapor are displaced by nitrogen N2, which does not form condensation on the internal surfaces of the optics during a sharp temperature drop.

Large field of view . The convenience, efficiency and enjoyment of binoculars depends largely on the field of view (angle of view) of the optical instrument. The larger the field of view (the wider the angle of view), the more space is included in the view. The field of view of these binoculars is well above the average of similar models and classifies these binoculars as premium optical instruments.

Outstanding near focus. Most users use binoculars only to observe distant objects. But not everyone knows that the best examples of binoculars provide significant opportunities for macro observations. The minimum focusing distance (focus limit) of this model is only 1.8 meters, which allows you to view flowers and insects in their real habitat. Binoculars with a focus limit of less than 2.5 meters are considered premium optical instruments.

Magnesium Alloy Body. Magnesium in various alloys is widely used to produce a wide range of products with high performance. The ratio of specific gravity to strength characteristics makes magnesium alloy a practically uncontested material for the manufacture of super-strong cases of optical devices. Optics in such cases will have a longer service life.

Center locking diopter. The diopter correction mechanism in this binoculars has a non-standard central placement. This allows for more precise adjustment without hitting the mechanism when the eyecup is rotated, as is often the case with standard placement on the eyepiece. What's more, the mechanism has a lock-lock that ensures that the settings are not accidentally shifted.

3 Stage Eyecups. Properly designed eyepiece frames not only increase comfort during long-term observations, but, first of all, allow users with different eye anatomy, as well as users with glasses, to use the binoculars with the same convenience. These binoculars use fairly soft retractable eyepiece frames of the Twist-Up type, which have 3 levels of fixation.

Tripod mountable. Despite the fact that in most cases observations are carried out with binoculars in hand, there are situations when mounting on a tripod is simply necessary. High magnifications, long-term observations or shooting on a smartphone camera with binoculars require a stable position of the binoculars. This model has a tripod adapter thread located under the cap in the front hinge.
