PocketWizard N10-ACC-1 Pre-Trigger remote cable allows you to remotely trigger Canon cameras that are equipped with the N3 remote shutter release terminal. It controls the half-press function using certain PocketWizard radios. It helps you in pre-triggering function i.e. holding your remote camera’s shutter half-pressed for metering and focusing positions before clicking the images. These cables come in the length of 3 feet (91.5 cm) or 1 foot (30 cm). The cable is packed in an eco-friendly recycled paper box that has a white label to indicate both ends of the cable and list the compatible equipment.
