The SC-28 provides full TTL control for Nikon Speedlights when used off camera with Nikon D-SLRs that utilize a TTL hot shoe.
One end slips into the D-SLR's hot shoe and the Speedlight attaches to the other end, when the Speedlight is used off-camera, on a bracket.
The SC-28 is approx. 9-ft in length and coiled.
