(will be available by end of day)
The AC5 RF Soft Shield provides RF shielding from certain Canon flashes emitting high levels of radio interference that impedes the AC5 from "hearing" the triggering information being sent from your transmitting PocketWizard and thus limits its operating range. The Canon flashes that need shielding are the 430EX, 580EX and the 580EX II. If you own the 430EX II or 550EX you do NOT need the AC5 as these flashes do not emit high levels of interference.
To receive your free AC5 RF Soft Shield you must already own one or more PocketWizard FlexTT5 Transceivers. You will need to provide the serial number from each FlexTT5 Transceiver you own. AC5's will begin shipping on a first-come, first-served basis beginning mid to late November. PocketWizard will post a news update when they begin shipping on their News page and Facebook pages.
The AC7 RF Shield, a hard plastic shield with 1/4-20 mounting inserts and umbrella holder, will also be available in November. If you are also interested in the AC7, you may indicate this on the form and we will contact you when they become available. With either the AC5 or AC7 in use you will see a significant gain in operating range.
