Sekonic RT-BR Broncolor Transmitter

Add a 2.4 GHz Broncolor-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 all 99 Radio Studio Addresses and 40 Lamp Addresses for remote triggering within a 98.4′ range. This radio control also permits adjusting the modelling light power and enables Broncolor users to more easily measure the ambient-to-flash light ratio and flash duration.
