Using the TI - GEAR - S is straightforward. First, mount it securely on your rifle according to the instructions. Turn it on, and you'll quickly see a clear thermal image. Use the controls to adjust settings like brightness and contrast for the best view. When aiming, take your time and steady your shot. For reconnaissance, scan the area slowly to spot any heat sources. As for maintenance, keep it clean. Use a soft cloth to wipe the lens and the body. Avoid using harsh chemicals. Store it in a dry place when not in use. If it gets wet, dry it thoroughly. And always follow safety rules when handling it. Don't expose it to extreme temperatures or impacts.
