SIB 16×40WP Gyro Stabilizing Binocular incorporates gyroscopic image stabilization technology. This is the best known technology, which allows for the maximum angle of stabilization. It enables the user to observe distant objects from moving platforms without degradation of the image resolution, which is typically caused by mechanical vibrations or normal hand tremors. Combining fully coated, computer designed optics, with high-speed internal gyro stabilizing system, the SIB 16×40WP is the ultimate instrument for long-range observation, tracking and surveillance. SIB 16x40WP is fully waterproof and this feature makes it irreplaceable for professional marine users.
