By using the highest optical grade PMMA material, the Sea & Sea 30205 Universal Dome Port 210 has a refractive index close to that of glass, allowing a high degree of light transmission. The port is designed with usability in mind, as the dome can be replaced quickly and easily on the spot in any environment. In addition, the dome is also supplied with an additional bayonet mount to provide compatibility with Nauticam housings. For compatibility, consult your housing's port system chart.
