Ideal for adding an additional receiver to other flashguns or strobes when using Infrared sync cells would not be of use over long distances or in daylight conditions. By adding the receiver to another flash on the same channel you can control your lighting to the full. Identical to the receiver in the INT492 trigger set except without the transmitter. Supplied with P.C.Sync cable and batteries. This product will not work with INT412 due to variances in frequencies.
