Optical Performance
- Powerful magnification allows for detailed observations of distant subjects 
- Compact objective lenses ensure slim optical tubes to maintain a compact form 
- BAK4 roof prisms deliver a round exit pupil, and a crisp and clear image with limited edge distortion 
- P40 phase-correcting prism coating increases light transmission while improving contrast and clarity 
- HDC fully multi-coated system has abrasion-resistant and anti-reflection properties to protect exterior lens surfaces, and improve light transmission and contrast 
- HighLux-System (HLS) maximizes light throughput to improve color rendition and contrast 
- Hydrophobic AquaDura coating on external optical surfaces allows dirt, dust, and fingerprints to be removed easily 
Use and Handling
- Closed-bridge/dual-hinge configuration provides a sturdy platform for the internal focusing mechanism 
- Textured long, yet low-profile, center focusing wheel helps to maintain an overall compact form while still being easy to manipulate 
- Wide 34-74mm interpupillary distance range accommodates use by a wide variety of users — especially those with narrow faces like children and adolescents 
- ±3.5 right-eye dioptric correction allows user to compensate for optical prescription 
- Twist-up rubber eyecups for comfortable use with or without eyewear 
- 15mm eye relief makes long-duration glassing sessions more comfortable with reduced eye strain 
- 2.5mm exit pupil 
Construction Details
- Dual-hinge design allows optical tubes to fold under the bridge for an ultra-compact form factor when closed, to take up less space in packs and pockets 
- Lightweight and durable aluminum alloy chassis 
- Matte-black rubber armor provides a slip-resistant grip, especially in cold and wet weather 
- Nitrogen-filled and O-ring sealed to be fog and waterproof (submersible to a depth of 16.5 feet) 
- Compact 4.4 x 4.4" form factor is easy to pack and carry 
- Light 9.3-ounce weight
