Info about utility of Cam Caddie Scorpion EX

[FoxAdriano]

Do you think Cam Caddie Scorpion EX is useful with AX100? I never used handycam and I'd like to clear my ideas.

Some users tell it is useful as for handling as for balancing and stabilizing a handycam like AX100 because vibrations reverberate on the handle.
I'd like to use it for to make documentaries in my trips.
