It sounds ok Mike. But to be honest, I'm not really that impressed with the sound playback. But that's cool. Cause they told me if I wasn't happy with the mic I could replace it. (they've had the odd bad mic)
I'll give you the link to source one. It's local and the person I dealt with was really good to deal with. Her name is Aimee Nicolle. She really knows her stuff! She's into 4X4ing big time to. She's good friends with Rick at 4X4 Accessories. That's where I meet her to pick up my cam kit.
The model I brought was the "xtreme helmet camera kit" package. It's the highest resolution helmet camera on the Australasian market. It's a 560TVL Sony Super HAD. It ain't cheap though Mike. $800.
Tell her I put you onto her. She might do you a better deal.
