Got one here. Its broken in to three pieces, nothing that a bit of duct tape and some putty can’t fix.
Seriously, nobody does away with his mast unless it is broken or in some other way utterly unusable.
However, you don’t have to buy a new mast as advertised. Seldén/Proctor also sells a bare mast, the aluminium profile tapered at the top. It takes a few hours to cut it to length, drill the holes and move the small parts from the old mast to the new one. Though the supplier uses a fancy milling machine it can also be done with some patience and elbow grease with nothing more then a (battery) power drill and some files. I did it last summer with my boom and paid about one third of what a ready made boom with all the parts attached would have set me back. Ask your supplier about it or better call Seldén/Proctor direct.
Questions don’t cost, only the answers do.
