Nauticam N120 9.8" (250mm) Dome - Deep version (100m)

4.597,01 (3.799,18 without VAT)

Out of stock

Nauticam's optical glass dome ports are finely ground to the highest level of precision and represent the state of the art in both manufacturing and optical technology. Different sized ports are available to support a wide variety of lens and housing types. Port adapters or extensions may be required for some ports and housings. This wide-angle optical glass port has a diameter of 250 mm and is part of the N120 port system.

The 18807 (N120) and 16405 (N200) dome ports, with a shallower 40 m depth, continue to be available in our product line and are still recommended for diving within recreational limits. This version is a more "rugged" variant designed to withstand deeper depths with a 100 m limit. The original designs are also lighter and less expensive.
