Most cameras these days come with some form of image stabilizer, whether it's optical or sensor-shift. However, these implementations have limitations. Taking shots with a telephoto lens extended fully or on a boat in choppy waters will amplify hand shakes that result in blurred images.
The Tyler Minigyro is meant for photographers who shoot from moving vehicles such as boats, cars, and even helicopters. Given that these modes of transportation usually vibrate a fair bit (and even more on rough terrains), you'll need a pretty good stabilizing system to get a clear shot of your subject.
The Minigyro is handheld and has an adjustable handle for shooting in various positions as well as a quick release mounting plate for speedy assembly. There are four Brute Gyro wheels that compensate for the motion as determined by the sensors in the device.
It appears that the Minigyro is not for sale on Tyler Mount's Web site, but it is available for rent. Rates can go from $400 to $1,600, depending on the rental duration.
