O.M.G. history (Officine Meccaniche Generali) starts at the end of the sixties.

    When, in 1968 Pirelli stopped the production of the oxygen scuba-diving gear for the Italian Navy, O.M.G. decided to plan and to produce a new closed circuit oxygen rebreather taking into consideration the experiences and the solutions adopted in the Pirelli respiratory: the Caimano. It followed in the nineties the introduction of a more modern and efficient apparatus, Manta 97, an Oxygen re-breather ( A.R.O.) a lighter model (only 11 Kg outside the water ready for the use) with an autonomy of nearly 5 hours, that it was produced and sold specially to the foreign countries.

    Later the study and research allowed the development of a new system of the Caimano family that in 1997 reached with the definition of the model Caimano MK2C, planned and realized in collaboration with the R&D Office of the Italian Navy.
    We are proud to assert that the series Caimano has become a "standard" of high quality in use, not only to the Special Units of the Italian Navy, but of all the Italian Special Forces. The models A.R.O. supplied to the National Fire Departments, the Red Cross and the Italian Civil Protection and the semi-closed circuit AZIMUTH rebreather for the recreational, civil/professional market, had much success, either in Italy than to the rest of the world.
    After the unit Caimano MK2C O.M.G. designed other models for the Military operators with higher specialization like automatic rebreather, Nitrox Rebreather and for the SDV operators.

    Currently the latest model is the Caimano MK4C DV. O.M.G ability has allowed to grow the capacity to supply all the materials of logistic support and underwater communication systems, and a complete range of tactical material dedicated to the raiders operators and the sportive/ recreational activity.
    Today O.M.G. is a Company leader for quality, technology and full range of equipment for the military and professional market.

    In July 2011 the merger with OMG Italy, the Italian leader in the design of special equipment for breathing and underwater operation, places SIEL at the top of this industry.

    Today SIEL collaborates with military authorities and special forces worldwide in an international context.
