This Dot Line Dual Off Camera TTL Shoe Cord can be used to trigger two Nikon-compatible TTL flash units simultaneously, from the same camera hot shoe. Each of the three cable sections is 3' long, and the junction point between the cables has a female 1/4"-20 thread. The hot shoe terminals have locking shoe mounts.
This cable maintains all on-camera flash functions, including i-TTL operation.
