LOWER PRICE! The ELB400 Hi-Sync One Head Kit, when used in conjunction with the Skyport Plus HS Transmitter, is a portable and powerful answer to the problem of using high shutter sync speeds reliably to freeze action or balance bright daylight with flash. Elinchrom's exclusive Hi-Sync technology enables the camera to be fine-tuned to the brightest part of the flash curve to make full use of the available power, works with speeds up to 1/8000th sec, and provides more power than other competing portable hypersync options. The ELB400 power pack provides 424w/secs of power and can be set to recycle in under 2 secs, or for greater battery economy in ECO mode for 3.5 secs recycling speed. Its OLED display is easy and intuitive to use, with the option of 3 shooting modes, and the lithium cell has an impressive capacity of 350 flashes.
