The regulator uses an R-600 balanced diaphragm first stage .
The balanced diaphragm design helps maintain a stable intermediate pressure as tank pressure and dive depth change, ensuring consistent air delivery and easy breathing in a variety of diving conditions.
The R-600 is designed as an extremely compact first stage. Its design allows for a reduced overall weight and size of the regulator, making the RS609 convenient not only for regular diving, but also for travel when weight and space are important.
The first tier includes:
The symmetrical arrangement of the connectors provides more opportunities for convenient hose routing according to the diver's equipment configuration.
The RS609 second stage is designed to make breathing as natural and smooth as possible.
The front part of the second stage is made of stainless steel and has a mirror finish. This gives the structure not only a unique appearance, but also additional resistance to operating conditions.
The RS609 has an enlarged purge button that is easy to press even when wearing thicker diving gloves.
TUSA Demand System reduces friction and air resistance between moving parts, allowing the valve to open and close more smoothly, allowing the diver to breathe more naturally.
The Advanced Flow System uses a specially shaped, curved housing design that helps direct airflow more effectively and ensure a more even air supply to the second stage.
This is one of the key technologies of the RS609, helping to achieve easy and smooth breathing.
The regulator has Click Spring Adjustment breathing resistance adjustment.
The adjustment mechanism allows the diver to adapt the breathing characteristics to his preferences and diving conditions.
The RS609 comes with a TUSA Ortho-Conscious Mouthpiece .
The mouthpiece design with flexible edges is designed to reduce tension in the jaw area and provide a more comfortable and stable grip. This is especially important during longer dives when the mouthpiece is held in the mouth for a long time.
The regulator is supplied with a Miflex® flexible low-pressure hose .
Its flexibility allows the hose to adapt more naturally to the diver's movements and reduces stretching and strain on the second stage. This helps reduce stress on the mouth and jaw area.
The white RS609 version uses a white Miflex® hose, matching the regulator design.

The RS609 kit is listed at around 957g with the first stage , while the R-600 first stage is around 630g.
The RS609 first stage is a balanced diaphragm design , while the R-600 can be equipped with the EK-600 cold water kit for use below 10 °C. The DIN-R600 conversion kit also allows the use of a DIN connection up to 300 bar / 4350 psi.
Therefore, if the regulator will be used in cold Lithuanian water, it is important to choose the right package and follow TUSA usage and maintenance requirements.
The RS609 is perfect for divers who value:
easy breathing + low weight + comfort + compactness.
Thanks to its light weight and flexible Miflex® hose, it is also very suitable for traveling divers who want to reduce the weight of their diving equipment.
TUSA RS609 is the choice for the diver who wants a high-end regulator with a balanced diaphragm first stage, convenient breathing control, and a comfortable second stage.
