The new RF-603 II is the Mark II improved version of the RF-603. It is a remote shutter release as well as a multi-functional radio flash trigger which can synchronously trigger flashes and studio strobes. Through the transceiver based system, each unit can be used flexibly as trigger or receiver. Only 2 AAA batteries are required to power each item.
The 2.4GHz wireless frequency is suitable in most countries and guarantees high speed, distance and stability. Within capacious areas, the remote control distance has a working range of up to 100m. The synchronisation speed can reach to 1/320, depending on the situation it may reach to 1/250 or less.
A set consists of two equal transceivers. Both of them can act as a receiver as well as a transmitter. It can trigger one flash with one set, since one serves as trigger and one as receiver. You can also buy additional transceivers to trigger two or more flashes at the same time.
