Quick Answer

Attach the Flash Link Optical Cable to your Sea Dragon light and optically synced strobe, ensuring a secure fit and clear optical path for reliable flash triggering underwater.

Why Use an Optical Cable Instead of a Wireless Trigger

Underwater, wireless triggers can suffer from interference or misalignment. The Flash Link Optical Cable provides a direct, physical connection that avoids these issues, ensuring consistent firing in all light conditions and aiming positions.

The cable's coiled, flexible design in a durable casing prevents kinks in the optical channel, so you can position your light and strobe without worrying about signal loss.

  1. Check compatibility: Confirm your strobe or flash is either a SeaLife model or one that supports optical sync. The Flash Link Optical Cable works with all SeaLife or optically synced flashes/strobes. Using a non-optical strobe will not work—check your strobe's manual.
  2. Attach the cable securely: Connect one end of the Flash Link Optical Cable to the Sea Dragon light's sync port and the other end to your strobe's optical input. Ensure both connections are snug and fully seated. A loose connection can cause intermittent firing—double-check both ends.
  3. Position the cable to avoid kinks: Route the cable so it is not sharply bent or pinched. The coiled design is flexible, but the durable casing prevents kinks in the optical channel, so keep the cable free from obstructions. Avoid tight bends—this can damage the optical channel over time.
  4. Test the sync before diving: Power on your Sea Dragon light and strobe, then trigger the light to confirm the strobe fires in sync. Test in different aiming positions to ensure reliable firing. If the strobe doesn't fire, recheck the connections and try again.
