Mantis 1 (M1)



A precise blend of form and function, the new Mantis 1 is a direct evolution of the Meridian watch computer. About as versatile as a dive computer can get, Mantis 1 provides an operating system for virtually every type of in-water activity, including Closed Circuit Rebreather diving.

Comprising the perfect balance of both topside and underwater functions, the Mantis 1 uses the Human Factor DivingTM approach to product design, constantly analysing your biometrics to deliver a custom dive profile that maximises safetly and bottom time.
