Windage and Elevation Adjustment
The CTS-25 is fully adjustable for both windage (horizontal) and elevation (vertical). The adjustment screws are located on the top and right side of the sight body. These adjustments are made by removing the turret caps and using a small flathead screwdriver, a coin, or a cartridge case rim.
- Elevation Adjustment (Top Turret): Turn clockwise for down adjustments and counter-clockwise for up adjustments.
- Windage Adjustment (Right Side Turret): Turn clockwise for left adjustments and counter-clockwise for right adjustments.
Note: Adjustments to both the windage and elevation knobs reference your Point of Impact (POI). Should your impacts be below your point of aim, dial UP to reach Zero.

Maintenance
To ensure the longevity and optimal performance of your Crimson Trace CTS-25 Compact Sight, follow these maintenance guidelines:
- Cleaning: Use a soft, lint-free cloth to clean the lenses. For stubborn smudges, a lens cleaning solution designed for optics can be used sparingly. Avoid abrasive materials or harsh chemicals.
- Storage: Store the sight in a cool, dry place away from direct sunlight and extreme temperatures. Ensure the lens caps are in place to protect the lenses from dust and scratches.
- Battery Life: The sight offers approximately 1 year of battery life with normal use. Replace the CR2032 battery annually or as needed to prevent unexpected power loss.
- Durability: The sight is designed to be shock, impact, fog, water, and vibration resistant. While robust, avoid unnecessary drops or impacts that could compromise its integrity.
