The Altimaster Galaxy was developed from the Classic Altimaster III but with significant improvements. The most obvious upgrade is the user replaceable lens and significantly larger numbers on the faceplate. The Galaxy has an altitude range of 18,000 feet marked in 250 foot increments meeting the needs of most skydivers. It contains a durable and precision mechanism and comes complete with hand mount. A wrist mount is also available. Available in feet or meter faceplate. A Glow Face model is also available for night jumps. Available in a wide variety of colors.
