The TX50 has been one of, if not the best performing regulator in the world for a number of years, due to its pneumatically balanced 2nd stage with integrated venturi system and diver adjustable cracking resistance control.

With this level of control it is possible to tune the regulator to your personal breathing requirements.

The excellent cold water performance of the TX50 is due to the highly efficient heat exchanger system on the 2nd stage and the dry, environmentally sealed 1st stage. Four medium pressure ports are mounted on a swiveling turret with two high pressure ports on the body. The first stage also has a unique personal identification facility. The TX50 uses the DST first stage with DIN fitting. Details of the DST first stage can be found in our technical section.

In January 2004 the U. S. Navy's Experimental Diving Unit in Panama City, Florida, produced a report on the performance of the Apeks TX50. These official test results identify the Apeks TX50 as a candidate for 'Authorised for Navy Use (ANU) listing' as an open circuit underwater breathing apparatus suitable for use in cold water temperatures.
