Product Information
The Fantasea FA-3 LED Strobe Trigger is a fiber optic strobe trigger that fires underwater strobes and flashes in sync with a camera's hot-shoe connection, using fiber optic cables instead of the camera's built-in flash. It has 2 LED ports, a 10,000 flash capacity on a full charge, and connects to any camera featuring a hot-shoe connection.
Who it is for
This trigger is for underwater photographers who want to eliminate reliance on a camera's built-in flash when firing external strobes through a camera housing. Removing the built-in flash from the triggering process extends camera battery life, allows for longer shooting sessions, and reduces camera heat buildup, which helps limit condensation in humid conditions. It is also suited to photographers using Fantasea Mirrorless Housing models equipped with Fantasea's Hybrid Vacuum Safety System M16A.

Compatibility and sizing
The FA-3 can be installed inside any camera housing that offers a fiber optic slave strobe connection and sufficient space anywhere inside the housing for the main unit. It is also compatible with Fantasea's Mirrorless Housing models equipped with Fantasea's Hybrid Vacuum Safety System M16A. The trigger is capable of firing most underwater strobes on the market, with the exception of the Sea&Sea YS-D2, which cannot be triggered with the FA-3. For best and most reliable performance, use quality multi-core fiber optic cables. Note that strobe output is controlled manually only when using the LED Strobe Trigger.
