The TDS Tac Black regulator has been designed from the well-known and successful TDS's Gull Z Tek , for the special units of different armies. With a completely black design characteristic in the tactical bodies, the Gull Tactical reduces the size of the first stage, making it more compact by eliminating the rotating turret and maintaining the double membrane system for cold water. It is perfect to use in single mounting, or assembly in twin tanks, sidemount or independent stages in a single tank. Available in both INT and DIN system, the one used in the armies due to the greater reliability in high pressures, compact size in the fitting with the valve as if reliability against shocks with objects of the valve and first stage.
