Performance and Passion – The new SG Regulator Line with innovative Optimal Flow Design Valve

“The new regulator line offers a high performance system with a modern design at an unbeatable price. The applied technology ensures natural effortless breathing – whether diving in tropical or in ice cold waters. Our technicians have no doubt that the new SG range sets a new standard in SUBGEAR regulator technology.”

 Georg Fraunhofer, Technical Manager

OFD: The OptimalFlowDesignTechnology

Uncompromised Airflow:

The innovative OFD valve reduces the air flow resistance, delivering an impressive work of breathing effort in comparison to the downstream valve. As the air flow is directed around and not through the spring any air resistance is eliminated resulting in an optimal air flow.

Perfect for the cold and rough:

The lever fixation is located in the poppet centre, offering the ideal technology for cold water diving.

High Flow Rate:

The poppet stroke is up to 3.5mm and guarantees the optimal air flow.

Optimal Venturi Effect:

The shape of the diaphragm was designed to fit the high airflow due the poppet’s stroke. The result is a perfect venturi effect.

Reduced Work of Breathing due to the Advanced Design

Take a look at the housing shape: Due the lower position of the diaphragm center compared to the mouthpiece centre, the hydrostatic pressure is increased. This has a positive benefit during the inhalation phase. The work of breathing in the vertical position has been reduced.

Furthermore there is no venturi vane in the mouthpiece area; this means no cross section reduction. The air can flow directly to the mouth, without obstruction. The Venturi effect is eliminated due the angle of inflow.

“As we developed the SG50, we wanted to create a system that made diving more fun. I think it is safe to say that we have achieved this. Thanks to the power flow downstream valve we can offer a smooth and natural feeling air flow in a compact system. The balanced diaphragm 1st stage with a dry chamber guarantees a reliable system suitable for every diving environment. We added the stainless steel casing as an exceptional product deserves a beautiful finish.”

 Corrado Cominetti, Research & Development Manager

SG50: The High Performance System for Every Situation


The advanced regulator technology provides the ideal system for safety, reliability and peace of mind whatever the conditions. Equipped with a convenient swivel joint, every dive with the SG50 will be an uncomplicated and relaxing experience – in every type of water.

  • Diaphragm 1st stage with dry chamber
  • Adjustable inhalation effort
  • Work of Breathing: 0,64 J/l








SG30: The Tough but Light Regulator


The SG30 is a proven compact and sturdy system ideal for recreational divers who are constantly on the move and need an all-rounder that can perform in any water. The diaphragm 1st stage is the preferred choice of cold water divers – excellent performance guaranteed.

  • Balanced diaphragm 1st stage

DiveAlertPLUS: a Dual Function Surface / Subsurface Signalling Device




DiveAlertPLUS is a specially designed, small, lightweight pneumatic signalling device that uses quick-connect/disconnect hose couplings to become an integrated part of your power inflator.

It uses a small amount of air from your SCUBA tank to make a piercingly loud sound in air or water. It can be heard a mile away from where the diver in need is above water.


How it works

The DiveAlertPLUS uses chrome-plated brass couplings to attach to your power inflator. Squeezing the device engages the actuator valve stem causing a small amount of air to flutter a stainless steel diaphragm emitting a piercingly loud sound. The subsurface/underwater signal is produced by a percussion “buzzing” noise made by a piston hitting a stainless steel diaphragm much like a drum.
