Frequently Asked Questions

How deep can it go? +
The 6'' Dome Port V1 is rated for depths of up to 40 meters (130 feet), ensuring reliable underwater performance.
Acrylic or glass dome port — which should I choose? +
Acrylic ports deliver solid image quality in most scenarios, and they have the advantages of being lighter, more affordable, and easier to repair. Glass dome ports, while offering slightly superior image quality in specific conditions and better scratch resistance, cannot be repaired if scratched.

The 6" domes deliver excellent image quality in most shooting conditions while being significantly more compact and travel-friendly, making them the preferred choice for many users. While 8" domes can offer slightly improved edge sharpness, their larger size makes them bulkier and less convenient to transport.
How deep can I use this port? +
The '' Dome Port is rated for depths of up to 40 meters (130 feet).
Is it compatible with my Sea Frogs housing? +
This port uses a 90mm (3.54'') bayonet mount. It is compatible with most Salted Line / Sea Frogs housings, excluding A6xxx and RX1xx series models.
