The Bowens Pulsar Tx is an ultra compact, lightweight transmitter with a low profile design that insures proper camera balance for more comfortable shooting.The functionality of the Pulsar Tx is controlled without the need for external switches. Two push buttons provide full control over the 24 radio zones and the test flash function. The channel and studio selections are indicated by a row of LED’s, with the signal transmitted by a solid antenna for added durability.The Pulsar Tx features a unique ‘click-lock’ system that attaches the transmitter securely to the camera hot shoe, without the need of an additional thumbscrew. The transmitter remains firmly in place when shooting horizontal or vertical, while the lightweight design insures there is no loss of connection. The power management system of the Pulsar Tx keeps the unit in low-power mode until more energy is required, which insures long battery life.The Pulsar Tx is sold as a transmitter only, and requires at least one Bowens Rx or compatible receiver. Additional compatible items also include the Pulsar Receiver Card (BW5170), Gemini monolight models, or a Pulsar Transceiver (BW5150) for use with light that have a standard sync socket.
