Great price!
This is exactly what I needed. Works perfectly and a fair price… I saved some money from buying brand new! Thanks!

Great module and works seamlessly.
Works great. Update Sekonic to its latest firmware before using this otherwise it won't recognize the module. That's what happened to me.

Transmitter for Sekonic L-858D-U (MODEL:RT-GX)
Hello, I recently purchased this product for my Sekonic L-858D-U, and when I installed it on my light meter, it didn't work. When I held the transmitter in my hand, I shook it and it made a rattling noise inside. Could the transmitter be faulty? Can anyone give me their opinion on whether they hold the transmitter in their hands and when they shake it, it makes a rattle-like sound? Is this normal? Thank you for your comment.
