Our top of the line high performance boom, with a full carbon body and tail extension. It features a reduced diameter hand grip for ultimate comfort and control, with only a 26mm grip on the 140-190 model. The monocoque (one piece) profile gives a market leading stiffness and strength. The double pin lock system provides optimal load distribution and a stiff connection between the boom body and tail end, even when maximally extended. The robust front incorporates an anti-friction lever and an integrated mast shim, for RDM masts. If you are looking for a boom without limits, the Simmer Black Line is your choice of preference.
