Steiner Tactical T1042 10x42 Binoculars

A 10x compact runs out of light before the day does. The Tactical T1042 is the answer when you need that same ten-power reach to keep working into dawn and dusk: a 42 mm objective and 4.2 mm exit pupil feed the eye far more light than a pocket binocular can, so detail holds up when the sun is low and the shadows are deep. This is the full-size tactical 10x for glassing that starts before legal light and ends after it.

Steiner's High-Definition Tactical optical system and advanced coatings deliver high-contrast, neutral images, and a 20.5 twilight factor indicates strong low-light reach for a 10x binocular. The housing carries NBR Long Life rubber armor over a nitrogen-sealed, waterproof body rated to one-meter submersion, so weather and impact stay outside the tube.

The Fast-Close-Focus wheel pulls focus from a close six feet out to infinity with minimal rotation for tracking moving targets, and the one-button ClicLoc mount attaches or releases the strap or harness instantly.

Key Features

• 10x42 low-light margin. A 4.2 mm exit pupil and 20.5 twilight factor keep detail usable at dawn and dusk.
• High-Definition Tactical optics. Advanced coatings for high contrast and true, neutral color.
• Fast-Close-Focus. A minimal-rotation center wheel pulls focus from a 6 ft close focus to infinity.
• Waterproof and nitrogen-filled. Submersible to 1 m and fogproof across temperature extremes.
• NBR Long Life armor and ClicLoc. Impact-resistant grip and one-button strap changes.

Ideal For

• Hunters and shooters working low light who need 10x detail with a genuine dawn-and-dusk margin the compacts cannot give.
• Observation and overwatch from a fixed position, where a full-size objective earns its weight.
• Buyers weighing reach against carry: for a pocketable 10x step down to the T1028 10x28; for a brighter low-light view and always-in-focus operation, compare the T750 7x50.
