Maintenance Tips
-
Clean optics gently: Use the included lens cloth and a soft, microfiber cloth with lens‑safe cleaner to remove fingerprints, dust, and debris — the fully multicoated HD optics and ArmorTek exterior coatings need careful handling to maintain clarity.
-
Always use lens covers: Keep tethered objective and eyepiece covers on when not in use to protect glass from scratches and environmental damage.
-
Avoid touching glass surfaces: Oils from fingers can reduce light transmission and image quality; handle by the body/rubber armor only.
-
Dry and store properly: Although argon‑purged and O‑ring sealed for waterproof/fog‑proof performance, drying thoroughly before storage prevents moisture buildup.
-
Wipe exterior after use: Clean rubber armor and metal body to remove dirt, oils, or salt that can degrade materials over time.
-
Use a tripod or adapter: 15× magnification amplifies shake — use the included tripod adapter to reduce strain and provide steady, long‑range viewing.
-
Check focus/diopter: Adjust central focus and diopter regularly for sharp, balanced views across both barrels.
