Maintenance Tips

• Clean UHD lenses carefully: Use a microfiber cloth and lens-safe cleaner only. XR™ Plus coatings and ArmorTek protection need gentle handling to maintain maximum light transmission and sharpness.
• Keep lens covers on: Always use tethered caps and rainguard to prevent scratches, dust, and moisture buildup.
• Avoid touching optics: Fingerprints reduce clarity and can degrade coatings over time—especially noticeable in high-end UHD glass.
• Store in dry conditions: Argon-purged and O-ring sealed for waterproof/fogproof performance, but prolonged humidity can still affect seals.
• Wipe exterior after use: Rubber armor and magnesium chassis are durable, but removing dirt, oil, and debris preserves grip and longevity.
• Use harness for support: Included GlassPak harness reduces strain and protects binoculars during field use.
• Check focus & diopter: Ensure smooth center focus and locking diopter for consistent, sharp viewing across both barrels.
• Use tripod for extended viewing: Tripod adaptable design helps stabilize image for long observation sessions.
• Avoid extreme temperatures & impacts: Protects internal optics, coatings, and precision alignment.
