The PocketWizard MultiMAX Transceiver is the WORLD'S most innovative and advanced Digital Radio Triggering system available in the photographic market. With such distinctive features such as integrated Trigger Time Control software, True Trigger Confirmation and Selective Quad Triggering only to mention a few, it's no wonder the MultiMAX goes far beyond the expectations of wireless triggering. The MultiMAX features Wireless Transceiver Technology, which eliminates the need for a separate transmitter and receiver setup. Each MultiMAX provides the capability to send and/or receive digital signaling by a flip of a switch, similar to personal communicators. Among many advantages, a photographer can select between a transmitter or receiver mode as shooting assignments change. The MultiMAX is the only radio system that offers True Trigger Confirmation feedback, up to 1600 feet away or more, without the need for signal repeaters or daisy-chained radios. Selecting which camera or flash zone fires is as easy as pressing a button in "Selective Quad Triggering" mode. The MultiMAX automatically confirms radio triggering on every zone simultaneously, with immediate visual and audible feedback on the MultiMAX (set for transmitter).
