i have a sony handicam hc-21. I used some camo tape to put over it, and i covered up the little speaker that made a beep when i turned it on, but thats the only beep it makes.

I put my thumb over it as well when i turn it on, and you cant hear it at all.

i haveit on a tri-pod with a remote so i can record and zoom without touching the camera. It works prett well...

you can check out my first hunting video i made....its alittle shakey..
