A boom means you can have your light source over and above your subject. Its often overlooked but can be very helpful for photographers.
This boom is fairly light weight but OK for photography, small lights, stobs with an umbrella. A large softbox you may struggle.
There is a counter balance with a hook to hold to double bag on the end. This comes empty. We used 2 unopened bags of rice.
