Used Flashpoint ZeroGrav 2-Axis Digital Gyro Stabilizer

Experience a extra level of mastery over the challenge to tame camera movement with the new Flashpoint ZeroGrav G 2-Axis Digital GYRO Stabilizer for your DSRL or BMCC! This gyroscope accelerometer grip is a new generation of high strength,high efficiency 2-axis precision devices, detecting the angular velocity and acceleration of the camera in three dimensional space, calculating the camera position, providing an amazing level of stability assistance for the most complex motion tasks. The gyros within compensate for any and all unstable movements when they are calibrated correctly. A lithium powered gyro motor, through calibration of inertial measurement in tandem with the sensors, software parameters and application, controls Pitch and Roll/Yaw. You can greatly increase the speed at which you are able to handle the action or enhance the illusion of dreamlike floats through space. The affordable cinematographer's tool takes you places you never dreamt of for a serious fraction of the price of previously available technologies.

Just insert a charged battery, power up, hold the stabilizer for 5 to 8 seconds while the gyro completes its self-inspection, and you are ready to enjoy all the thrill of the most gentle and flowing camera movements. The customized balance of your particular imaging device is simple as well, with all the adjustments on the base plate. Twin handles for graceful grip, center of gravity assurance, and pitch balance no room for error. Perfectly fashioned links, exquisitely finished surfaces, and silky smooth mechanism. Your shot is stable no matter the challenging motion and assured to astound the most demanding director.

The innovative ZeroGrav G adds more phenomenal features to the family of FLASHPOINT ZEROGRAV Stabilizers, with which you can accomplish impossible marvelous camera-in-motion shots without a dolly or 'flying' boom and crew, defy forces of gravity and master the physics of flexible balance, perform amazingly fluid walk-thru's and mobile-pans with grace and flare. Walk, run, go up and down stairs, and shoot from vehicles in motion and over uneven terrain without any instability or camera shake when recording video while hand-holding.

A gyroscope is used in the camera bracket to help stabilize the rate of rotation around the camera roll axis. As the camera moves, the gyroscope will counteract non-zero values until the platform levels out, whereupon it would read a zero value to neutralize the direction of "level." The best example of reading a gyroscope is that of the altitude indicator on typical aircrafts. It is represented by a circular display with the screen divided in half, the top half being blue in color to indicate sky, and the bottom being red to indicate ground. As an aircraft banks for a turn, the orientation of the display will shift with the bank to account for the actual orientation of the ground.

Hand-held stabilizers for binoculars and cameras have been around since the 1950's and have been used extensively in the media industries as a means to stabilize film and video imaging. There are numerous scenarios where the camera is subject to buffeting, causing unwanted blurring or shaking. Gyrostabilizers enable shots that would otherwise be impossible. A well-known example is the chase scene in the forest from the film Return of the Jedi. The filming required ultra-smooth shooting as the cameraman walked and ran through the forest floor. The final footage was then sped up, giving the illusion of a rapid and fast but intensely smooth chase scene.

Newton's first law of motion states that a body in motion continues to move at a constant speed along a straight line unless acted upon by an unbalanced force.

Precession

If you have ever played with toy gyroscopes, you know that they can perform all sorts of interesting tricks. They can balance on string or a finger; they can resist motion about the spin axis in very odd ways; but the most interesting effect is called precession. This is the gravity-defying part of a gyroscope. The different sections of the gyroscope receive forces at one point but then rotate to new positions! When the section at the top of the gyro rotates 90 degrees to the side, it continues in its desire to move to the left. The same holds true for the section at the bottom -- it rotates 90 degrees to the side and it continues in its desire to move to the right. These forces rotate the wheel in the precession direction. As the identified points continue to rotate 90 more degrees, their original motions are cancelled. So the gyroscope's axle hangs in the air and precesses. When you look at it this way you can see that precession isn't a mystery at all -- it is totally in concordance laws of physics!
