The PocketWizard Plus II transceiver system does more than cut the cord. The PocketWizard Plus II can wirelessly trigger lights and/or cameras within a range of 1600 feet of the transceiver. Utilizing advanced wireless technologies, four 16-bit, digitally-coded channels are available for selective firing of lights, or when working in ‘crowded’ environments. If speed is a concern, images can be captured at a rate of up to 12 frames-per-second, which outpaces most currently-available cameras, pro or otherwise. Ultra-fast microprocessors allow for top sync speeds of 1/250th-second for focal-plane shutters and 1/500th for leaf shutters.The PocketWizard Plus II is compact, with a short, unobtrusive, rubberized antenna. The total height of the transceiver and antenna is less than 6.5”, and it weighs in at 6oz including the batteries. To ensure a secure fit to your camera or bracket, the Plus II features sturdy locking rings for hot shoes. Power is supplied by 2 AA batteries, which are good for about 60 hours of playtime. An optional AC adapter allows for continuous, unlimited shoot time.
