The Bowens Pulsar Tx Radio Trigger and Receiver Card Kit is a 24-channel remote triggering system designed for use with Bowens Gemini flash heads.
Radio slaves are more dependable than infrared, or optical slaves and avoid a tangle of wires on set. The Pulsar Tx Receiver Card operates on the 433Mhz radio frequency which is immune to interference and failure. The feather-weight (0.28 oz) slips into the socket on your Gemini flash head and includes an antenna. The Pulsar Tx Receiver has a range of 80' and needs no batteries for operation. It's triggered by the included Pulsar Tx trigger which slips easily on the hotshoe of your camera.
