Furthermore, it is a sustainable design that can be used with new cameras in the future with minimal parts replacement.
Newly designed fiber-optic cable cover included. Prevents optical cable terminals from falling out and smartly protects light-emitting panels and cable terminals. Includes a strap to prevent loss of the cover.

Made-to-order gear, such as certain Nauticam ports and extensions, takes longer — we’ll confirm the lead time with you before you commit.
Need it urgently? Tell us before you place the order and we’ll be honest about what we can commit to.
We don’t sit on orders. If something unforeseen slows yours down — a stock gap, a courier hiccup — we’ll tell you early and do our best to put it right.
We ship within Singapore by courier and worldwide via tracked international services. Import duties and local taxes are the responsibility of the recipient.
Products carry their manufacturer’s warranty (Nauticam, AOI, Kraken and others). If you run into an issue, reach out and we will help you with the claim.
