Opticron built their green 8x42 T4 Trailfinder Binocular with a magnification and objective lens size combination that is favored by many users for its versatility and portability. Added to that are features that boost performance from dawn to dusk in a wide array of lighting and environmental conditions.

These features begin with phase-corrected BAK4 roof prisms and broadband fully multi-coated optics that work together to deliver bright and clear high-contrast images with accurate color rendition through the entire visible spectrum and across a field of view that approaches wide angle. An exceptionally long eye relief and wide exit pupil, when combined with the optical performance, present the user with an immersive observational experience, even in low light. For those who want to make detailed observations at close range, the T4's minimum focus distance is under 5 feet so viewing nearby birds, bugs, flora, and fauna is comfortable and easy.

The chassis is made of a lightweight and durable aluminum alloy, and is nitrogen-filled to be waterproof and resistant to internal fogging. A protective green rubber armor provides a slip-resistant grip, with textured palm pads added for improved grip security in cold and wet weather. A large center focus wheel and convenient thumb-operated diopter adjustment ring on the right eyepiece enable precision focusing — even while wearing gloves. The T4 is tripod mountable with an optional adapter for hands-free use to limit vibrations or eliminate arm fatigue. Designed for active users who are always on the go, Opticron includes an ocular rainguard and tethered objective lens caps, minimizing the chances of loss.

Optical Performance
  • Moderate 8x magnification brings subjects close without sacrificing field of view or exit pupil, that is common with high-power optics
  • 42mm objective lenses draw in more light than smaller models to boost low-light performance without excessive bulk
  • Compact roof prisms help to keep the form factor slim for easier packing and hand-held comfort
  • BAK4 prisms deliver a round exit pupil, and a crisp and clear image with limited edge distortion
  • Phase-correction prism coatings enhance color fidelity, contrast, and resolution
  • Broadband anti-reflection fully multi-coated optics maximize light transmission to help produce accurate color fidelity across the entire visual spectrum, and further improve contrast and brightness
  • 57° apparent angle of view approaches wide angle to present an immersive observational experience
  • Short 5-foot minimum focus distance enables detailed observations of bugs, birds, flowers, and other plants at close range
  • 375-foot field of view at 1000 yards
Use and Handling
  • Closed-bridge configuration provides a strong base for the internal focusing mechanism
  • Large textured slip-resistant center focusing knob is easy to manipulate, even when wearing gloves
  • Right-eye dioptric correction allows precise focusing to individual eye prescriptions with a convenient thumb lever adjustment
  • Broad 58-77mm interpupillary distance adjustment range allows easy use by many users — even those with wider faces
  • Twist-up click-stop eyecups for comfortable use with or without eyewear
  • Tripod mountable with optional adapter for hands-free use to reduce arm fatigue and/or vibrations
  • Exceptionally long 21mm eye relief makes long-duration glassing sessions comfortable without eye strain
  • Wide 5.25mm exit pupil will completely cover most pupils as they dilate in low light for brighter and clearer views without vignetting
