Sekonic RT-GX Godox Transmitter

Add a 2.4 GHz Godox-compatible radio triggering protocol to your Speedmaster L-858D-U light meter. Able to be fitted into meter’s housing, this module provides multiple functions beyond triggering, including access to 32 channels and up to 16 groups and Wireless IDs for remote triggering within a 98.4′ range. This radio control also permits adjusting the modelling light power, supports high-speed sync (HSS) flash metering, and enables Godox users to more easily measure the ambient-to-flash light ratio and flash duration.
