Port Options

The best camera in the world can't make up for poor optics. Poor optical design and materials introduce ‘image killers’ – distortions, aberrations, degraded resolution, or vignetting.  Gates family of Precision Ports are sharp and clear: the finest optics for the finest underwater images.  No image killers.

Professional to amateur, super wide to macro, Gates Precision Ports suit a wide range of needs, conditions and experience. Of course all ports are backed by our legendary customer support and the same standard of excellence expected of all Gates products.
