o-TURTLE 2 RC SMART+ TTL trigger for Olympus / Panasonic

A reliable TTL and Manual trigger for underwater photography. This trigger works via fiber optic cable or sync cord and due to its LED technology the battery of your camera last longer

This underwater TTL trigger was developed for Olympus and Panasonic mirrorless camera systems. The new o-TURTLE 2 RC SMART + TTL trigger works in Manual or TTL mode which you can change during dive. The o-TURTLE 2 RC 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 RC SMART+ has a new, more durable metal hot shoe and it lets check the battery status from the setup software.

RC mode available in OLYMPUS systems.
