Don't fret, Arthur! Help is on the way!

The Kenlab gyros spin at a high RPM, creating a resistance to movement in two out of three axes. Think of a child's gyroscope and how it resists falling over.

In practical terms, when used with cameras it proves resistance against shake or vibration, artificially stabilizing the camera it is attached to. It is a strange sensation since it seems to be "fighting" you, keeping you from making sudden movements. The drawbacks are that they are relatively heavy, noisy (they emit a high-pitched whine), power-hungry and expensive. I'm not convinced that they have any place in the DV world, despite their appearance on the oddball Glidecam setup. They are sometimes used on professional Steadicams for high wind or long lens type work, but even there they are not an ideal technology for the reasons listed above.

So what you are saying is we need some three-ring laser gyros to detect motion and some servo driven weights and suspension arms to stabilize the motion, eh?

Did you know they tried to stabiize the first missle subs with large gyros? The bearings would burn out in a heartbeat as the relatively puny gyro tried to stabilzie a 400 foot long submarine.
