Maintenance Tips
-
Keep lens clean for accuracy: Use a microfiber cloth and lens-safe cleaner—dust or smudges can affect precise ranging performance.
-
Maintain secure mounting: Regularly check Picatinny rail attachment to ensure consistent zero and reliable ballistic calculations.
-
Protect sensors & housing: Built-in environmental sensors (temperature, pressure, humidity) should be kept free of debris for accurate ballistic data.
-
Battery care: Replace CR123A battery as needed and remove during long-term storage to prevent leakage or power issues.
-
Avoid harsh impacts: While rugged, impacts can misalign the laser or affect zero retention under recoil.
-
Dry after exposure: After rain or humidity, wipe down and air-dry to preserve electronics and internal components.
-
Check zero & calibration: Periodically confirm zero and ballistic profiles to ensure accurate drop and wind solutions.
-
Keep firmware/app updated: If using ballistic apps or Bluetooth remote, ensure updates for optimal performance and compatibility.
