Bowens Multi-functional Transceiver Pulsar Radio Slave Trigger, for Cameras, Flashes & Meters.

• This multifunctional device can be used to trigger flash units, film and digital cameras and light meters for up to 100 meters. Because it uses radio transmission, rather than IR, it allows for triggering around corners, through walls and is not affected by high ambient light situations.
• Choose from four individual channels and six studio selectors, each providing a unique ID for a different flash device or combine them to trigger all equipment within a given setup or studio. Pulsar also features a hot-shoe mount, sync in and sync out terminals, a ready indicator, a test button and an external power option.
• Because of its low-voltage operation, it is perfect for digital cameras. Each unit can be used as either a transmitter or receiver and operates off of two AAA batteries.
• Precision, Power and Digital Dependability, The Pulsar has four separate channels, enabling the photographer to isolate various light sources or to combine them and fire them all at once without leaving the camera. Additionally, the Pulsar has a studio selector switch, which provides isolation from other Pulsar units using the same channel, and allowing up to six different systems to operate independently in the same studio or shooting space.
• It also has a five way channel selector switch that allows the photographer to select all flash heads to fire simultaneously or to fire up to four heads individually.
• The Pulsar features radio instead of IR transmission, allowing it to trigger around corners and through walls. It is also unaffected by high ambient light orlow-light situations. The Pulsar's low-voltage operation takes the fear out of connecting an expensive digital camera to a high voltage studio lighting system.
• Other features include a co-axial PC sync out connection that allows photographers to use their existing sync leads, a DC input socket that allows for long term installations, and a test button that will allow the Pulsar to be tested without shooting any pictures.
• Each Pulsar is two units in one and can be switched to either TX (transmitter) or RX (receiver) mode. Once switched on, the indicator lamp on top of the unit will blink approximately every three seconds to show that the unit is working. This same LED will light to show when the unit is transmitting or receiving a signal. The LED also acts as a low battery warning and double blinks when the batteries need changing.
• To physically attach the Pulsar, when it's being used in receiver mode, to a flash unit, a bungee cord and connector plate are included. Using the elastic cord, the plate can be attached to the light unit or stand. The hot shoe slides onto the connector plate and is locked into position, providing a simple, effective and safe design.
