Professional courses for GMT Technicians

Poseidon holds its Technical Service standards to the highest level. With such advanced diving equipment, an equally high-quality maintenance network is essential.

To ensure this, Poseidon has established a global network of certified Service Centers, authorized to carry out inspections, servicing, and repairs on all regulators, full-face masks, and rebreathers in the product line.

Access to this network begins with the Poseidon GMT (General Maintenance Technician) course. This training provides comprehensive instruction on the full range of Poseidon regulator systems—Cyklon, Jetstream, and Xstream—as well as the Atmosphere full-face mask. Participants gain detailed knowledge of regulator function, diagnostics, disassembly, maintenance, reassembly, and final calibration.

Participants will learn to:

Understand the function of Poseidon regulators including the Cyklon, Jetstream, and Xstream systems.
Diagnose issues effectively using systematic procedures.
Disassemble, clean, and reassemble regulator units with precision.
Perform proper maintenance and final calibration.
Adhere to strict quality control measures within the global service network

The course is led by Poseidon Pro Academy GMT Instructor and concludes with official Poseidon GMT certification.
