Our verdict

A rugged high magnification binocular for hunters and long range observers who can brace it or use a tripod. Field of view and eye relief are missing, and the listed weight looks wrong.

Overview

Not a rangefinder or a digital optic, the Sig Sauer ZULU4 is a manual focus binocular with large objective lenses for long range and low light viewing. Roof prisms in a closed bridge body carry the image, and the housing can attach to a tripod.

Strong magnification and wide objectives bring distant game into view, and the coating set reduces glare and reflection. A sealed, impact resistant body suits wet field use. Handheld viewing at this power shakes, so plan on a tripod or a rest for long sessions.

Who it's for

Hunters scanning far hillsides at dawn and dusk get high power and large lenses in a sealed body. Birders who follow fast movement in close cover should choose lower magnification.

Pros and cons

Pros
  • High magnification for distant detail
  • Large objectives for dim light
  • Fully multi-coated lenses
  • Waterproof, fogproof and impact resistant
Cons
  • Listed weight of 3 ounces looks implausible
  • Field of view and eye relief not listed
  • Box contents unclear in the listing
  • High power magnifies hand shake

Performance notes

Image brightness at dusk follows the exit pupil, which is set by objective size divided by magnification. Multi-layer coatings cut light lost to reflection at each glass surface. At high power every tremor is enlarged, so a tripod decides how much detail you actually resolve.
