This system offers the same performance as the brass version, but in a sophisticated and lightweight package:
Machined titanium body and components for the MK25T, from a solid block of titanium.
Titanium trim ring and plate for the S600T.
SCUBAPRO has been the leader in the evolution of piston controlled first stages since its beginning; the MK25 carries on this heritage with an array of patented features ensuring unfailing performance. The MK25 is a balanced piston first stage, our absolute top performer. It is a superior regulator thanks to its ultra stable intermediate pressure resulting in an extremely punctual and constantly high delivery of air. This means instant airflow at any tank pressure and water temperature for a real carefree dive.This Titanium version means same quality and performance but in an ultra sophisticated and lightweight package.

Machined titanium body and components from a solid block of titanium.
Air balanced flow-through piston- First stages with air balanced pistons deliver significantly more air to the second stage than any other first stage, while their performance is totally unaffected by the changing tank pressure.
Two opposite high pressure ports- The arrangement of high and low pressure hoses is crucial to diving comfort. Two opposite high pressure ports allow for an individual positioning of the first stage (pointing up or down). This allows the diverto position the gauges either on the right or left side and increases the freedom of movement for head and neck.
Multiple low pressure ports- For ultimate freedom in the arrangement of low pressure hoses, the MK25 accommodates five HF (high flow) ports on a swiveling turret, which allows for 360 degree swivel of hoses. High flow ports deliver about 15% more air than conventional ports.
DIN/INT first stage configurations- To ensure worldwide compatibility, all SCUBAPRO regulator systems are available in a 232bar INT version as well as 300bar DIN versions.
