I liked my VholdR so much that I recently picked up a ContourHD. Both units are plagued with wind noise... I haven't compared, but the CHD seems to pick up the wind noise less. After reading countless articles in this forum about the mic, could it be that the mic is simply picking up the wind noise from the unit itself? Rounding out the front facet directly beneath the camera may cure the wind noise issues. Maybe some neutrally round shape that joins flush with the three edges of the unit lower unit. Something formed from blue foam w/bondo and some 100mph tape (duct tape) to secure it to the unit... or maybe the right sized super ball.

I also read a thread regarding the wind noises translating to the mic from the unit casing. Sounds valid. A solution for that could be neoprene tape (or sound deadening material like dynamat) around the aluminum camera casing. Basically, deadening the wind vibrations on the unit...

Anyway, I thought I'd run the ideas by some of the more experienced dabblers on this forum for a sanity check.
