they are the Shimano EF-50 EZ-Fire that came with the Escape 2.

thanks for watching. Having the camera on my chest is nice, but i like being able to look left and right to shoot things I pass.

Having it on my helmet is more noticeable for drivers, who see it and drive more respectfully thinking they are on camera.

I will likely try mounting my original hero to my chest and hero 2 to my helmet to film with them at the same time, and experiment with editing them together.
