Radio Trigger battery operated

The transmitter sits on camera's hot shoe and sends encoded (16-bit digitally encoded) radio signal to trigger a remote flash, a studio strobe or a flash power pack up to 3000 W/S to which the receiver is attached. The transmitter contains a tiny user-installable 12V alkaline photo battery (included) and has a function of sleeping mode when standby (getting rid of on/off switch). So it has super low power consumption and can trigger some 20,000 times with one battery.

Effective range: 100 feet/30m approx.

The receiver has a standard 1/4" phone jack plug for attachment to many studio flashes using this type of connection. It also comes with one 1/8" (3mm) PC sync plug adapter which is designed for use with studio flash/strobe that use this type of connection.

The transmitter has a TEST button so you can trigger your remote flash manually for metering purpose. The item also comes with a PC sync cord for cameras that do not have a hot shoe. Measurement: Transmitter - 60mm x 48mm x 37mm, Weight: 1.3 oz (with battery) / Receiver - 85mm x 55mm x 25mm, Weight: 1.2 oz (without 2 AA batteries).
