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.

SWP44C Port

Super Wide Port SWP44C

The SWP44C Super Wide Port is the most distinguished member of the Precision Ports family of underwater optics from Gates.  110° wide angle and full zoom through macro capability enables the clearest, sharpest, distortion-free underwater imaging possible – a necessary requisite for any Ultra High Definition venture.

High Performance optics 2
High Performance

An 'all in one' port, the SWP44C provides 110° diagonal FOV and full zoom through capability for macro imaging.    

110° Rectilinear Super Wide Angle

for Humpbacks, Mantas and Dolphins, the SWP44C has a remarkable FOV -- and rectilinear, too.
