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
- 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.
S600T second stage
A second stage regulator must translate natural breathing
behaviour into mechanical reality. A high quality second stage can
signiﬁcantly reduce stress and enhance diver safety by providing
smooth, low-effort breathing response, resulting in ample yet
controllable quantities of air.
- Same performance as the brass version, but in a sophisticated
and lightweight package: Titanium trim ring and plate for
- The air-balanced
valve technology of SCUBAPRO's S600 second stage
features a balancing chamber in the second stage mechanism,
slightly offsetting the force of the downstream air entering from
the first stage.
- Precision molded carbon fiber & technopolymer
friction, light weight, corrosion and cold water resistant for long
life & sturdiness.
- Diver adjustable
inhalation effort. This feature enables the diver to
adjust breathing effort via an oversized control knob.
- Venturi Initiated
Vacuum Assist (VIVA). Another SCUBAPRO patented feature,
the VIVA is available on all SCUBAPRO second stages. VIVA uses the
power of a vacuum assist to reduce work of breathing and increase
mouthpiece. SCUBAPRO uses a comfortable orthodontic
mouthpiece on every second stage to reduce jaw fatigue and gum
irritation. It was developed by dentists and dental laboratories
and lasts longer than any other mouthpiece, because only a minimum
effort is needed to hold it comfortably in place.
- Sturdy high flow hose with kevlar lining for extra durability
and flawless air delivery.
- Super high-flow exhaust valve provides the lowest
exhalation effort and better breathing comfort.
