Care & Maintenance
Mounting & Alignment
- •Ensure the clip-on is properly aligned with your day scope's objective — misalignment causes image shift.
- •Re-check mount tension after the first 5 shots; mounts can settle during initial use.
- •Use only the included mounting hardware — aftermarket mounts may not maintain alignment.
Lens Care
- •Clean both the front (thermal) and rear (optical) lenses with microfiber cloths only.
- •Keep both lens caps on during storage and transport.
- •Blow off dust before wiping to protect the germanium coating.
Storage & Environment
- •Store detached from your rifle in its protective case.
- •Avoid extreme heat — the thermal sensor degrades with prolonged high-temperature exposure.
- •Store batteries separately for long-term storage.
