A critical device for any serious studio shooting, remote triggering, syncing of different types of light systems, etc. Pocket Wizards are the utility device of nearly all serious pros out there who need a way to transmit and then receive a radio signal to different types of equipment. Because they are radio based, they work through glass and walls. With an accessory cable, you can use 2 to create a long distance remote release. (Ive personally used it over 200 feet).

Highly Recommended for Studio Shooting.
