The Altimaster II was originally designed by Stephen L. Snyder almost 50 years ago. The Altimaster face is internationally recognized.
Steve Snyder introduced the Altimaster concept of: 0-12,000' which was founded on the belief that most people are accustomed to reading a clock face, and that a freefall takes about 60 seconds -- one sweep of the second hand. The needle points at the numbers and does not cover them up.
The Altimaster II contains a durable mechanism made from temperature compensating metals for minimal friction and precision accuracy with an altitude range of 18,000 feet.
Ideal for mounting on a chest pad.
