You may ask why you need a trigger, the answer is simple: so you can, aim and pull the trigger to start filming / photo-burst or to stop filming.

As this is a metal system you can put your GDOME and Trigger into even the biggest of breakers, without worrying that it may break (like other plastic options out there)!

There are multiple mounting on this rig that can be used for various applications including light systems, external mic systems and so on.
