The Leupold BX-5 Santiam HD 10x42 Binoculars, part number 174483, are a full-size open-bridge magnesium roof prism binocular delivering 10x magnification on 42mm objectives, with a field of view of 114 m at 1,000 m (341 ft at 1,000 yds) and 16.6 mm of eye relief, at 689 g (24.3 oz).
Behind the 42mm objectives sit phase-coated BaK4 roof prisms and Leupold's Professional-Grade Optical System, with DiamondCoat 2 on the exterior lens surfaces and the Guard-ion hydrophobic coating that sheds rain and fingerprints. The open-bridge magnesium chassis is rubber-armoured and 100% waterproof and fog-proof, focuses down to 1.5 m (5 ft), adjusts from 56–74 mm between the eyes, and carries twist-up eyecups and a built-in 1/4-20 rotatable tripod adapter port.
How It Compares
The 10x42 is the all-round choice in the BX-5 Santiam HD line and the format most stalkers settle on — 114 m of field at 1,000 m (341 ft at 1,000 yds), 1.5 m (5 ft) close focus and 689 g (24.3 oz) round the neck all day. The BX-5 Santiam HD 8x42 gives a wider 126 m field and 18.5 mm of eye relief for 20 g less if you glass more than you judge; the BX-5 Santiam HD 10x50 keeps the same 10x but puts it behind a 50mm objective for dusk and dawn, at 893 g (31.5 oz) and a longer 3.5 m close focus.

Frequently Asked Questions
Is 10x42 the right format for UK stalking?Yes — 10x42 is the standard UK hill and woodland stalking format. It gives enough magnification to judge a beast at distance while keeping a 114 m field at 1,000 m (341 ft at 1,000 yds) that is quick to pick up movement, and at 689 g (24.3 oz) it is light enough to carry all day and steady enough to hold freehand.
Will the BX-5 Santiam HD 10x42 work with spectacles?Eye relief is 16.6 mm and the eyecups twist up and down, so you can wind them flat, keep your spectacles on and still see the full 114 m field at 1,000 m (341 ft at 1,000 yds).
Will it stand up to British weather?The BX-5 Santiam HD 10x42 has a rubber-armoured open-bridge magnesium chassis and is 100% waterproof and fog-proof, and the Guard-ion coating sheds rain and fingerprints from the exterior lens surfaces.
Can it be used on a tripod?Yes — the BX-5 Santiam HD 10x42 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 10x50?The BX-5 Santiam HD 10x50 has the same magnification behind larger 50mm objectives and 19.3 mm of eye relief, which helps at first and last light, but it weighs 893 g (31.5 oz) against 689 g and focuses no closer than 3.5 m. The 10x42 is the better walking binocular.
Is this genuine Leupold stock?Yes — factory-new Leupold stock dispatched from the UK.
