The XMSR Flash Trigger from Bowens is a 16-channel / 8-group transceiver designed to fire Bowens's recently introduced XMS500, XMS750 and XMS1000 flash heads. The full-function trigger will also control the flash heads' power level, modeling light, flash ready indicators and channel selection from distances up to 100'. Because of its transceiver design, the shoe-mount XMSR will also fire a connected camera using a second XMSR. The flash trigger operates on the 2.4GHz frequency and is powered by 2 AAA batteries.
