System

• Each Pocket Wizard Plus II is capable of acting as a receiver or transmitter. The unit's default mode is receive, but the Auto-Sensing Transceiver Technology allows it to switch back and forth between transmit and receive as needed, depending on how you set the units up on your hot shoe or with sync cords. The Plus II has four 16-bit digital channels so that you can trigger four groups at once -- or set up groups in different parts of the room and have them on different frequencies -- so that they only trigger when you select that unit's frequency.
  
  

Speed and Range

• The Plus II can trigger cameras or lights at up to 12 frames per second, which is faster than the current fastest DSLR on the market. The Plus II can trigger in 1/2000 of a second, which allows the unit a fast shutter sync speed of 1/250 of a second on your camera, enough for everything but the fastest action shots. The unit's range is 1,600 feet, which allows sports arenas to set up a Pocket Wizard Plus II over basketball nets or hockey nets for flash photography of action shots; the frequency will be posted in the photographer's pit, so that you can sync your Plus II with the arena's.
  
  

Frequency Differences

• The U.S. version of the Plus II uses a different transmittal frequency than the European and Japanese versions, and they are not compatible with each other. The U.S operates on 344.04 MHz, while the European works on 433.62 MHz and the Japanese version works on 315.50-317.00 MHz. That means if you are traveling and want to use your Plus II with units in foreign countries, you will need to buy one designated for use in that country.
