This underwater TTL trigger was developed for Olympus and Panasonic mirrorless camera systems. The new o-TURTLE 2 SMART TTL trigger works in Manual or TTL mode which you can change during dive. The o-TURTLE 2 SMART underwater flash trigger is the perfect choice for the demanding underwater photographer who needs a reliable TTL converter that works with the most popular underwater strobes (Inon, Ikelite, Sea&Sea, Subtronic). As the LED of the trigger controls the strobe instead of the built-in flash of your camera, the battery of the camera lasts much longer, so you need to open the underwater housing less often. The o-TURTLE 2 SMART has a new, more durable metal hot shoe and it let check the battery status from the setup software.

The package contains the o-TURTLE 2 SMART TTL trigger for Olympus/Panasonic cameras and the LED panel (150 cd LEDs) or the special cable for sync cord connection. If you want to connect your strobe via fiber optic cable, we recommend using a multicore cable! (Please write Us about which kind of connection you use. We also recommend writing us about what kind of underwater strobe will you control with the TURTLE trigger so we can set up the unit you ordered.)

The setup software for PC is downloadable from our website: you can find it on the right side of the page. If you need the MAC version, you can find it in the official APP store.
