Hawke Frontier ED X 10x42 Binoculars - Grey

The Hawke Frontier ED X 10x42 (product ID 47032401887539) delivers 10x magnification through a 42mm objective lens. That combination gives you a 112m field of view at 1000m and an exit pupil of 4.2mm solid performance for birdwatching and wildlife watching in good to moderate light. At 725g it is genuinely light for a full-size 10x42.

The H7 optics system uses Extra-Low Dispersion (ED) glass paired with fully multi-coated lenses to control chromatic aberration and eliminate colour fringing. BAK-4 roof prisms with phase correction and dielectric coatings push light transmission to its highest level. The result is sharp, colour-accurate images with strong contrast. Water repellent coatings sit on the outer lenses.

The chassis is magnesium alloy wrapped in a textured rubber coating. It is nitrogen filled and waterproof to IPX7. Operationally tested from -15°C to +55°C. Focusing is smooth and precise with 15mm of eye relief workable with glasses. Every unit passes a strict quality control check covering resolution, light transmission and Strehl Ratio.

A lifetime manufacturer warranty backs the Frontier ED X. ED glass, dielectric prism coatings, IPX7 waterproofing and a magnesium alloy body make this a serious performer for field use.

The 10x42 format gives a 4.2mm exit pupil bright enough for daytime and low light use. ED glass cuts chromatic aberration by bending different wavelengths of light more consistently than standard glass. BAK-4 roof prisms with phase correction and dielectric coatings maintain contrast and push light transmission to its peak. Every unit is tested for Strehl Ratio which measures how closely the optics match a theoretically perfect lens. Nitrogen filling blocks moisture from entering the sealed body.

The chassis is magnesium alloy strong and light. It is wrapped in a textured rubber armouring that absorbs knocks and improves grip. The optical system uses ED extra-low dispersion glass elements and BAK-4 roof prisms with dielectric and phase correction coatings. Outer lenses carry a water repellent coating.

Use a blower or soft brush before wiping lenses with a clean microfibre cloth. Store in the hard case when not in use. Keep the hinge and eyecups free of grit. Avoid impacts and do not expose to chemicals. The lifetime warranty requires correct use and maintenance.
