Leupold BX-2 Alpine HD 8x42 Binoculars – 181176

The Leupold BX-2 Alpine HD 8x42 Binoculars, part number 181176, are a full-size Abbe-Koenig roof prism binocular delivering 8x magnification on 42mm objectives, with a field of view of 131 m at 1,000 m (394 ft at 1,000 yds) and 18 mm of eye relief, at 689 g (24.3 oz).

The 42mm objectives feed Abbe-Koenig prisms and Leupold's Advanced Optical System, fully multi-coated. The chassis is rubber-armoured and nitrogen-purged, 100% waterproof and fog-proof, focuses down to 4.1 m (13.5 ft), adjusts from 58–74 mm between the eyes, and carries twist-up eyecups and a built-in 1/4-20 rotatable tripod adapter port.

How It Compares

The 8x42 is the widest and steadiest model in the BX-2 Alpine HD line — 131 m at 1,000 m (394 ft at 1,000 yds), 18 mm of eye relief and 689 g (24.3 oz). The BX-2 Alpine HD 10x42 shares that weight exactly but tightens the field to 114 m and the eye relief to 15 mm; the BX-2 Alpine HD 10x52 adds a 52mm objective for low light at 865 g (30.5 oz) and focuses closer, at 2.8 m. Above this line, the BX-5 Santiam HD 8x42 moves to the Professional-Grade Optical System with DiamondCoat 2 and Guard-ion coatings, phase-coated BaK4 roof prisms and an open-bridge magnesium chassis.

Frequently Asked Questions

Is 8x42 the right format for UK stalking?8x42 is the easiest format to live with. The 131 m field at 1,000 m (394 ft at 1,000 yds) is the widest in the BX-2 Alpine HD line, 18 mm of eye relief suits spectacle wearers, and at 689 g (24.3 oz) it is comfortable on the neck for a full day on the hill.

Will the BX-2 Alpine HD 8x42 work with spectacles?Eye relief is 18 mm and the eyecups twist up and down, so you can wind them flat, keep your spectacles on and still see the full 131 m field at 1,000 m (394 ft at 1,000 yds).

Will it stand up to British weather?The BX-2 Alpine HD 8x42 has a rubber-armoured, nitrogen-purged chassis and is 100% waterproof and fog-proof, so a wet day on the hill or a cold morning in a high seat will not fog it internally.

Can it be used on a tripod?Yes — the BX-2 Alpine HD 8x42 has a built-in 1/4-20 rotatable tripod adapter port, which is worth using for long spells glassing one hillside.

How does it compare with the BX-5 Santiam HD 8x42?The BX-5 Santiam HD 8x42 is the same format on better glass — the Professional-Grade Optical System with phase-coated BaK4 roof prisms, DiamondCoat 2 and Guard-ion coatings, on an open-bridge magnesium chassis, at 669 g (23.6 oz) and with a much closer 1.5 m focus.
