For the development of the tactical Neptune MA-12 Altimeter the US special forces had a clear vison 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 needs to be settable in a pressurized aircraft.
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 are designed, engineered and produced in DeLand, Florida, USA.
