Product Description
The CowboyStudio FM 4 Channel Radio Trigger and Receiver Set is designed for photographic studio and on-location work to trigger various flash lights. The transmitter is attached on the hot shoe of the camera while the receiver is plugged into the studio flash, and each receiver works with one studio flash.
Radio triggers are best for photographers interested in range and reliability outdoors. It is also your best option if you want to have off-camera flash inside cars or behind furniture.
Unlike the standard NPT-04 trigger, the UNPT-04 trigger has a built-in umbrella holder. Additional NPT-04 receivers are available on our site.
