UW Technics NN-2/IS TTL Converter for Nauticam Housings with Nikon DSLR Cameras

UW Technics NN-2/IS TTL Converter for Nauticam Housings with Nikon DSLR Cameras

The UW Technics NN-2/IS supports both optical and electrical strobe triggering and is compatible with popular strobes from Inon and Sea & Sea. With these flashes, optical strobe triggering is the way to go. The fully automatic and manual functionality of the system is supported, and optical triggering eliminates problematic electrical sync cables.

Most of these supported Nikon cameras have a pop-up flash, and when used with these compatible strobes already offer automatic flash control. So why buy a TTL converter?

In these cases the main advantage of the flash trigger is speed. The recycle time of the camera's pop up flash is no longer a limitation, meaning continuous shooting and rapid fire sequences are now possible! Previously, continuous firing was only available with a manual triggering system, but UW Technics unlocks this capability with optically synced flashes in TTL exposure mode!

TTL is undoubtedly an important feature, but there is no disadvantage with this part installed in manual flash modes when you want them. This one product can serve as both a TTL Trigger (with optical or electrical sync) AND a manual flash trigger.

Simple, User Installable Design

Incredible Battery Life

Based on current draw, the TTL converter is expected to get up to 75,000 flashes on a set of CR2032 batteries.

Field Tested, NUSA Approved

This part has been exhaustively field tested, proving both reliability, and accuracy of the TTL system. The last thing anybody wants to do is ship a product that is going to create a pile of service orders, and we are have been continually impressed by the design and build quality of this TTL converter.
