Helmet cams are becoming more and more popular here. We purchased one a few years back for mountain biking training & still use it.

I have to say I think some folks on another local forum I puruse use them to complain about every single little movement by a motorist. This isn't directed towards you, it's just an observation.

If we were going to buy another one we'd get it from http://www.launchhelmetcams.com.au/ as we know most of the folks w the company ride!

I'd use them on the Audax rides I do as i'm often on my own...
