Description
Hawke Endurance ED Marine 7x42 monocular is equipped with premium class optics. The device has an IPX7 water penetration protection class, as well as protection against internal condensation, and is recommended for use in the middle of the water. In keeping with the high-quality optical device, the monocular is equipped with a BAK4 glass prism, which includes multi-coating of all optical surfaces, a rotary-hanging headpiece and a complete set. About those that are truly one of the finest monoculars, such as the inclusion of low-dispersion ED glass in the objective lenses and phase-correcting prism coating , which minimizes various types of optical disturbances, guaranteeing the transmission of a contrast image. The design with a mounted focusing wheel allows focusing with the fingers of one hand. In fact, these accessories have the same characteristics as large-size binoculars in the Endurance ED series, but lack the advantages of compact accessories for saving energy. Our belt, a bright yellow color, well-washed and not discolored by the water.
Extra Low Dispersion Glass (optical glass with ultra-low dispersion) ensures ideal color transfer of images and a high level of image quality. The coefficient of bending of the low-disperse glass is very low and has little to do with the frequency of the light (spectrum). All the light strands are broken to the same size, ensuring unprecedented clarity of the image. The curing of these glasses makes it possible to minimize aberration such as chromatism. The quality of ED-glass is very high, which means that manufacturers of high-tech sports optics stagnate in their premium class products. 
Phase Correction is a special phase-regulating coating that is applied to one of the surfaces of the prism wrapping system in the appearance of very thin balls. Phase correction is also necessary for the Roof optical system; fragments passing through such a prism, the light flow is decomposed into two parallel beams of light fibers, and the phase displacement occurs by half the amount light color, which leads to a change in the separation of the image, as well as a decrease in contrast. Phase Correction corrects the error. As a result, the image is as clear and contrasting as possible. The quality of such a coating is very high, and the application process requires precision precision, which is so technologically advanced that optics manufacturers can only afford it. Today, without a phase-correcting coating, the design of a high-viscosity optical device of the Roof prism system is practically inconceivable. 
The highly spherical wide-smooth coating of Hawke optics, however, ensures high light transmittance across the entire visible spectrum and provides high contrast and color rendering in natural tones.
BAK4 (barium crown) is a special type of optical glass, which is used for the production of prisms for optical devices. This material has a lower dispersion coefficient (light dispersion), which is less suitable for budget models. As a result, chromatic aberration is noticeably reduced (iris at sharp intervals between the transition from dark to light). In addition, a clear indicator of light bending allows you to eliminate vignetting (the phenomenon of trimming the light beam along the edges), which ensures uniform lightness of the image across the entire field of view. 
Waterproof - means that the optics are sealed with a strong O-ring and are protected from the penetration of moisture by being enclosed in a core extending 3 lengths to a depth of 1.5 meters. A static pressure at a depth of 1.5 meters does not affect the fit of the vehicle and does not affect its functionality. Such options are not scary in any weather mind.
Fogproof - means that the body is filled with dry nitrogen N2 in the middle, which prevents condensation of moisture on the internal surfaces at a temperature gradient, daily fogging in the middle, and therefore does not cause corrosion of the materials the vologgers are pouring in. The air is removed from the device and replaced with an inert gas (in this case, nitrogen N2), which does not allow water vapor in its storage and does not condense.
Today, polycarbonate is increasingly being used for housings of optical devices. This material is completely justified by its minimal strength, chemical, thermal, mechanical resistance and ease of processing. Polycarbonate housings are lightweight and shockproof. The stench does not attract additional expensive finishing treatment, such as anodizing or prefabricating.
The package includes an eyepiece cover and a lens cover with mounts on the body. The cover is very thick, has a thick mesh, closes with Velcro and can be attached to a belt.
- Possibility of mounting a tripod.
