Description:
The Evolution Inversion is a wrist mount altimeter. It measures 2 ½ inches at the bottom and tapers in to 2 inches at the top and weighs 4.3 oz. This altimeter comes standard with a 1 1/2 inch wide double overlapping wristband. It also has Free Fly friendly warning zones, and a counterbalanced movement.
After hearing concerns about the accuracy of a mechanical altimeter when it is inverted, we put together a series of tests to compare readings of our Evolution altimeters in various orientations.
The altimeters we used in the tests did not show any noticeable difference, and were consistent, regardless of orientation (when they were in a positive pressure environment, not in a burble).
However, if you apply theoretical gravitational influences to the design of the movement, you could conclude that the reading could be influenced, however minutely, by orientation. Since relative workers use the majority of altimeters, this has not been a concern because the goal is to stay in a horizontal position.
As a result of testing and research, we have come up with a solution for the issue. The Inversion altimeter, the first mechanical altimeter designed for free flying, features a counter balanced movement. The counter balancing of movement components eliminates any theoretical gravitational influence that may affect the reading consistency when inverted.
