Settings are accessed via rear panel push buttons and displayed on the easy-to-read LCD screen. Triggering options include sync cord, test button, and slave triggering. The SK400II weighs in at 2Kg, encouraging the assembly of a kit with two or more heads without having to lug a heavy case around.
SK400 II is a great unit, well built and with good recycling time, only goes to 1/16 but not a big issue. The only minus would be the light stand. It does support the strobe weight but when you put that strobe on an angle and extend the stand, it does start to bend under the weight pretty bad. Suggest using stronger stands.
