Walt Stearns Posted June 6 Share Posted June 6 This Sea & Sea port adapter allows Nauticam N120 port with the removeable locking ring to be converted into a working port on all Sea & Sea DX housings and Isotta housings with B120 port connection. To make the conversion, back out the 15 mounting screws remove the existing Nauticam port bayonet ring and replace it with this Sea & Sea port bayonet ring. It’s that simple. $40 with free shipping in the US Link to comment Share on other sites More sharing options...
