The Explore Scientific G400 Series 10x42 Binoculars are built for outdoor enthusiasts who refuse to compromise on brightness, detail, or durability. With 10x magnification and a 42mm objective, you’ll pull distant landscapes and wildlife into sharp, high-contrast view, even in dim dawn light. These binoculars excel in real-world field use—from forest trails to open prairies—delivering crisp imagery you can rely on when it matters most.
Why the G400 Series stands out
- Superior optical stack: Roof-style BaK-4 prisms paired with fully multi-coated optics, plus silver and phase prism coatings and high-reflective dielectric coatings. The result is brighter, more color-accurate images with improved edge-to-edge sharpness and contrast across the field of view.
- Bold field of view and close focus: A generous 325 feet (1000 yards) field of view makes scanning landscapes, tracking moving wildlife, and locating targets quick and effortless. Close focus of 2.5 meters means you can observe detail in nearby subjects without stepping closer.
- Designed for comfort in the real world: Twist-up eyecups and 15.1mm eye relief provide comfortable viewing whether you wear glasses or not, reducing eye strain during long observation sessions.
- Weather-ready reliability: Built to perform in challenging conditions, these binoculars are water resistant and ready for rain, splashes, and sudden weather changes—so your observations stay clear no matter the forecast.
- Complete for the field: Each pair includes a carrying case, strap, lens covers, and a cleaning cloth, giving you everything you need to protect and transport your optics from the moment you store them to your next adventure.
Who it’s for
- Hunters who need fast target acquisition, reliable weather sealing, and bright, high-contrast images to identify game at a distance.
- Birders seeking crisp detail of plumage and behavior across varying light conditions.
- Outdoor explorers and wildlife watchers who prioritize rugged construction, dependable optics, and ease of use in the field.

Practical tips for best results
- Adjust the eyecups to your eye relief preference before you start scanning to maximize comfort and field-of-view visibility.
- Let your eyes adapt to low light by giving your pupils a moment to dilate as you shift from bright to shaded areas, taking advantage of the G400’s bright optics.
- Use the included strap to keep the binoculars steady during long observations and to reduce fatigue on extended treks.
- Keep the lens surfaces clean with the provided cleaning cloth to maintain optimal brightness and contrast.
