For the development of the tactical Neptune MA-12 Altimeter the US special forces had a clear vision for tactical jumping: Small housing on the wrist with large numbers, no logistics for batteries/filters/maintenance and an easy to use product so the operator can focus on their main job. Due to the nature of tactical jumping the Altimeter/Audible needs to be settable in a pressurized aircraft. The MA-15 A has all of the features the MA-12 has plus 3 audible Alarms.

The result was an Altimeter which is widely used by tactical units worldwide. Drop tested from 6 feet (1.2 m) with 1000+G, waterproof up to 6 feet for one hour, built from machined aircraft aluminum.

All tactical Neptune MA-12/MA-15 A are designed, engineered, produced and tested in DeLand, Florida, USA.
