The SIG Sauer ZULU4 HD 12x50 Binoculars in Flat Dark Earth, part number SOZ40002, are the long-range model in SIG's value line and the cheapest 12x50 the company makes, giving 12x magnification on 50mm objectives over a 4.8-degree field of view (57.6 degrees apparent, approximately 84 m at 1,000 m) — for open hill stalking and night fox work over long fields.
LENSARMOR™, LENSHIELD™ and SPECTRACOAT™ coatings run through Schmidt-Pechan roof prisms, with SpectraCoat anti-reflection layers, LensArmor scratch-resistant outer surfaces and the LenShield hydrophobic coating. Twist-up eye cups give 15.5mm of eye relief, the non-locking dioptre offers +/- 3 of adjustment and interpupillary distance spans 58mm to 72mm. The rubber-armoured magnesium chassis is IPX7 waterproof and fog-proof rated, measures approximately 171 x 64 x 133 mm (6.75 x 2.50 x 5.25 in), weighs 954 g (33.65 oz) and focuses to 2.8 m; a foam carrying case and neck strap are supplied.
How It Compares
The ZULU4 HD 12x50 is the long-range model in SIG SAUER's value line, adding 50mm objectives and two more power over the ZULU4 HD 10x42 at the cost of 197 g and a narrower 4.8-degree field. It is the cheapest 12x50 SIG makes. Against the ZULU8 HDX 12x50 it gives up the metal chassis, the locking dioptre and a wider 5.5-degree field, and weighs around 246 g more. Against the CANYON HD 12x50 it adds a magnesium chassis in place of thermoplastic.
Ideal For
- Open hill stalking on a budget, where you judge beasts before walking
- Night fox and vermin spotting over long fields, where 50mm objectives matter after sunset
- Deer counts and survey work where you glass from a fixed position
- Anyone stepping up from 10x42 who wants more reach without going to a spotting scope
