Ikelite TTL exposure algorithms for underwater strobes has been famous for accuracy since the dawn of digital. Now you can enjoy the most reliable Canon TTL strobe exposure with a fiber optic connection between your Ikelite housing and DS strobes.

Replace your Ikelite flash bulkhead or 1/2-20 accessory port plug with this compact, independently sealed device, for reliable fiber optic triggering of an Ikelite DS Strobe (requires ). High frame rate burst shooting is supported when used with an Ikelite DS160-series or DS230-series strobe. 

The TT5 supports second curtain synchronization (i.e. rear curtain sync) and switching between TTL and manual strobe exposure using the camera's flash menu.

The transmitter is powered by two CR2032 lithium single-use or rechargeable batteries (not included). The Transmitter has a built-in power save mode which prolongs battery life. Expect at least a week of diving out with average use. It is always recommended to travel with a spare set of batteries.
