Combined circuit

The combined circuit, consisting of Optical TTL and Electrical TTL system is on a single board with both triggering methods available both separately or simultaneously.

Easy User Installation

Installation is very easy and takes around 1 minute. A user’s Manual is included with the circuit.

Easy control via the camera menu

TTL circuit is fully controllable via camera menu, including switching TTL / M, 1-st / 2-nd Curtain, Slow sync, +/- Flash Exposure Compensation, Flash Intensity Adjustment in M mode, Flash «Off» etc.

Special feature for M mode: Flash intensity adjustment in M mode, using camera wheel and camera scale

TTL circuit firmware has a special module which allows the photographer to use 3 variants of M mode, including both classic method and advanced methods. Advanced control allows the user to adjust underwater strobe light intensity manually via camera scale (approximately 1/64 to 1/1). In this case, the photographer does not need to operate the dial switches on the strobe body, and can just keep their hands on the housing, switch M mode and set the flash intensity via the camera controls.

TTL Accuracy

Tests showed fantastic TTL accuracy in a wide range of camera settings. The newest firmware contains an accurate TTL profile for each strobe type: Inon Z330, Z240, S2000; Ikelite DS161, DS160; Sea&Sea YS-D1, YS-D2, YS-250; Subtronic Pro-270, Pro-160. Strobe type can be easily set by onboard miniaturу 10-position rotary switch.

No mechanical switch ON / OFF

UW Technics TTL Converters don’t need any On/Off external switch. The device switches On/Off automatically by camera command. This is a very comfortable feature for the user, as there is no need to think about switching the device and a mechanical switch on the housing is not required.

Incredibly long battery life

Battery life is 5 years in continuous working mode. Products have micro current consumption from a pair of CR2032 batteries and automatic On/Off switch. User need not be concerned about the battery life of the device during a dive trip.
