On opening the ATC5K's box, I was a little disappointed about the camera. The earlier ATC3K I owned looked phallic, so I was expecting Oregon Scientific to have overhauled the appearance of this model. As they have attached a 1.5in screen it now looks like a reversed torch, and is both bigger and heavier.
The Drift HD170 is quite a special helmet camera. As the letters HD imply it will record at a resolution of 1080p, as well as in 720p and WVGA modes. Plus it will take 5 mega pixel photos. It’s pretty big – opening the battery compartment is like opening the wardrobe into Narnia – but in this case big is indeed better.
