The firing kit is a combination of transmitter and receiver in one package. This is the right choice for most customers. For more advanced users you can also provide a transmitter or receiver individually to tailor a package to their specific needs. The 3-mFiring kit is a true strobist solution that can be used to create a highly portable speedlight kit.
The 3-m receiver easily mounts to a light stand, holds an umbrella, and connects up to 3 speedlights. It uses the same 16 channel wireless system as other m-series triggers and receivers and has a 3.5mm sync socket to boot.
Note: Weight and dimensions do not include batteries or cords.
