All our PocketWizard radio devices are currently running the latest “legacy” firmware and have not been updated to the latest E-Release firmware released previously. Newer E-Release updated devices are not compatible with those running on legacy firmware, including third-party products using PocketWizard technology like light meters.

For controlling products that do not operate on legacy firmware, we recommend using the PocketWizard Plus IIIe Transceiver.

The FlexTT5 works with both the PocketWizard Plus III and Plus X models; however, the FlexTT5 may need to be synced to these units in order to function. To sync the FlexTT5 to another FlexTT5, a Plus III, or a Plus X unit, simply press and hold the TEST/LEARN button on the receiving unit until it glows a solid amber. While the receiver is doing this, press and hold the TEST button on the transmitting unit for a few seconds. This should sync the two units together.

The FlexTT5 has had a lot of problems with very short transceiver range. They sometimes lose signal from only a few feet away. If you need a more reliable unit, we recommend staying with the standard PocketWizards. They don’t do TTL, but they always work.

This rental includes a single FlexTT5 unit. You’ll need to rent a separate FlexTT5 or other PocketWizard unit to act as a receiver.
