This Sea & Sea TTL Converter III allows TTL exposure control when connected to Sea & Sea housings for Canon digital SLR cameras with Sea & Sea YS strobes except the YS-250Pro. The converter allows quick switching underwater between TTL mode and manual mode from outside the camera.
You can use the TTL correction dial after checking the results of a shot in the LCD monitor to adjust the amount of strobe light for the next shot. Because the converter comes with two top mounted strobe connectors, you can use advanced automatic TTL flash adjustment with two strobes. You can even use two different YS strobe models.

Comments about TTL Converter III for Sea & Sea Housings for Canon Cameras:
I use TTL Converter III for Sea & Sea housing to take underwater macro and fish portrait shots. This take the guess work out of the shooting in various light conditions.
Because it needs to be mounted on left hand side grip, the strobe positions on the left hand side is limited (can't be placed directly above the housing). The power switch on the TTL converter is too small, turning on power while wearing a 5 mm gloves is not too easy but manageable.
