Comments about Cavision Cavision Glass Fiber Mini Boom Pole for External Wiring, 3 Section, 7.6' (2.3m) Long, Supports 1.5kg.:

Very nice finish, lightweight and exactly the length you'd need for dialogue scenes of two. The boom bends a little as you use heavier mics, that is those with a radio and battery case, but nothing dramatic. One little comment: if you want to use the boom not fully extended, there is no way to keep the telescopic elements from sliding. You might want to use a length of gaffer tape to wrap around the elements at the appropriate length. This is not meant as criticism of the product, just a hint - using less than the full length boom might never happen to you.
