Since ordinary slave units will not work with most digital cameras (because these cameras use a very rapid series of pre-flashes, that trigger the slave prematurely), Wein is now offering the Digital line of slaves. A typical slave unit will fire on the pre-flash it senses while the digital camera captures the image on the last flash. These slave units are specially designed to only be triggered by the correct flash sensed by their built-in optical sensor and circuitry, thus solving the digital camera flash problem.
This Ultra sensitive slave has a range of up to 3000'. For indoor and outdoor useage. A built-in ambient light filter prevents interference from bright sunlight or false-triggering from flickering fluorescents. With "H"-prong (Household) connector and female PC socket.
