Overview / Product Description


TRT TTL I-Turtle 2 Smart+ TTL Flash Trigger for Nikon Cameras



A reliable TTL and Manual trigger that works via fiber optic cable or sync cord.

i-TURTLE 2 SMART+ underwater photo trigger for Nikon mirrorless camera models

The i-TURTLE 2 SMART+ underwater TTL trigger was developed for Nikon mirrorless camera systems. The "+" in the name indicates that this upgraded version can also control the new intelligent AOI strobe.

The new i-TURTLE 2 SMART+ TTL trigger operates in i-TTL Unified mode, allowing users to switch between Manual and TTL modes directly from the camera. It is the perfect choice for demanding underwater photographers who need a reliable TTL converter that works with the most popular underwater strobes.

Additionally, the i-TURTLE 2 SMART+ features a new, more durable metal hot shoe, ensuring enhanced durability and long-term reliability in underwater environments.

This special setup is designed for photographers whose underwater housing lacks a proper LED output. It can be installed in M14, M16, or even Ikelite inch-threaded housings.
