One radio transmitter
One radio receiver/trigger
One 1/8" (3mm) PC sync plug adapter
One 15" (35cm) PC sync cord
The transmitter sits on camera's hot shoe and
sends encoded (16-bit digitally encoded) radio signal to trigger
a remote flash gun to which the receiver is attached. The transmitter contains
a tiny user replaceable 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 continuously with one battery.
Effective range: 30 feet/10m approx.
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.
