Maintenance Tips

• Clean UHD lenses with care: Use a microfiber cloth and lens-safe cleaner only. The XR Plus coatings and ArmorTek layer need gentle handling to preserve clarity.
• Avoid touching optics: Fingerprints reduce light transmission and can damage coatings over time.
• Keep caps & harness on: Always use the included GlassPak harness and lens covers to protect against dust, scratches, and impact.
• Store in dry conditions: Although argon-filled and waterproof, long-term moisture exposure can affect seals and internal components.
• Wipe exterior regularly: Rubber armor and magnesium body are durable, but cleaning off dirt, oil, and debris extends lifespan.
• Use tripod for stability: 18x magnification amplifies shake—tripod use reduces strain and improves viewing precision.
• Check focus & diopter: Ensure smooth operation to maintain sharp, edge-to-edge image performance.
• Avoid extreme heat/sun exposure: Protects internal optics and coating integrity over time.
