Where everything began… the first Scubapro…

In the beginning of the 60’s Healthways started to sell single-hose regulators under the SCUBA-LINE.
Different models were available as Scuba Star and Scubair among a few others.
(We have a number of these regulators on display in our Makati showroom)

In 1962 Healthways founded a dedicated department under the name “SCUBAPRO” and all regulator models from then on were sold under the new SCUABPRO brand name.
The first available model was the SCUBAPRO SCUBAIR “J” (1962-1963) followed by the SCUBAPRO SCUBAIR 300 (1962 only). Both were existing Healthways models.
In 1963 Scubapro started to produce it’s own regulators as a separate company. The first was the extremely successful 108 which was available from 1963 to 1988.
(We have a number of 108 regulators on display in our Makati showroom)

PACIFICA was able to obtain one ultra-rare SCUBAPRO SCUBAIR “J”.
Therefore we are now able to show you where everything began. The complete set including first stage and pressure gauge are now on display in our Makati Showroom.

  • The articulated joint allows the blade to pivot and the entire blade is able to generate thrust. Pivot control technology ensures the most efficient  angle of attack is maintained no matter how hard or softly you kick, generating thrust without drag or wasted energy.
  • Clean water blade geometry for optimum propulsion. Water is free to flow onto the working section of the blade, drag is reduced and thrust increased.
  • Variable pivot control ribs insures that the most efficient angle of attack is maintained across all strengths of kick.
  • Ergonomic foot pocket with extended heel plate insuring ultimate power transmission with less leg strain.
  • Durable Monprene® construction making SeaWing virtually indestructible.
  • Wing tips arc upwards, increasing high-speed  stability.
  • Marine quality bungee heel strap with custom adjustment system for total comfort and convenience.
  • GORILLA version Recognizable by the grey strap and grey S

This could have gone wrong – Safety Tip –

Last week we received a regulator for maintenance with the DIN-Yoke adapter attached.
After removing the adapter we found a piece of coral-sand firmly wedged into the DIN Inlet which makes us believe that it might have been in there for a dive or more.

This can obviously lead to dangerous situations during a dive, especially when the air-consumption is high, like when diving in a current or in a stressful situation.

It should be good practice to have a look over the equipment before each dive.
Also a quick air-flow check should be performed by ALL divers before each dive.
Before entering the water take a few quick breaths from the regulator while watching the SPG.
If the needle moves while you breathe in, there is an obstruction in the air-supply like a blockage or half-closed valve.
Do not begin the dive until the problem is identified and rectified.

Dive Safe!!!

What is the difference? – First Stages

Piston or Diaphragm?

This question is about as old as both design.
What most divers don’t realize are how different the designs actually are and under which conditions they perform best.

While piston regulators feature fail safe down-stream valves and open unobstructed, delivering unrivaled amounts of air while extremely responsive, Diaphragm first stages require far more parts to work, open against the flow (so called Up-Stream Valve) and deliver smaller amounts of air due to the restricted air flow in it’s air-ways. Both designs have its strengths and weaknesses.

Unbalanced Piston

The Landrover of all Regulators.
This type of regulator is a reliable work-horse. With only two moving parts and minimum maintenance requirements is the Landrover of all regulators. Since the cost of ownership is minimal, it is found in most dive shops as rental regulator. It is also popular for it’s small size and low weight with travelers and used as stage regulator in the technical diving scene. It is suitable for moderate to warm temperatures.
The valve mechanism opens with the flow, a so called “fail safe – or – down stream valve”. This valve is able to open unobstructed and delivers large amounts of air on demand.
Since the design is unbalanced, the tank pressure influences the Intermediate Pressure (IP) slightly. The IP drops as the tank pressure decreases. This in general results in slightly higher breathing resistance towards the end of the dive.
The design has a open water chamber, allowing water to enter and act directly onto the piston, compensating for depth and adjusting the Intermediate Pressure accordingly.

The most popular model in this category is the Scubapro MK2 which was first introduced in 1963 and has been updated over the years. It is currently available as DIN 300bar, Yoke 200 bar and Nitrox Version to 100% O2.

Balanced Diaphragm Regulator

The Balanced Diaphragm Regulator is a popular design, working on the Upstream Valve Concept.

This type of valve opens against the flow of the air. The design is far more complex as compared to the Unbalanced Piston Design, resulting in 7 or more moving parts. A pin which runs through the center of the Orifice, reducing it’s opening controls the valve. This results in a reduced airflow as compared to other regulator designs.

The advantage of the design lies in a fairly compact size. The absence of a water chamber means no water enters the first stage reducing the risk of icing. The Water pressure is transmitted through a flexible Diaphragm.

In our experience the complex internal structure of these stages attract and accumulate more dirt, dust and debris as compared to other designs resulting in significant internal corrosion if not handled properly or if poor air quality is used.

Environmentally Sealed Diaphragm Regulator

The Environmentally sealed Diaphragm Regulator is a basic upgrade from the open Diaphragm Regulator Design.

It features a second diaphragm which seals the otherwise exposed spring against the environment, sealing all moving parts from the water, leaving only the external Diaphragm exposed. This also results in a lower temperature within the first stage as the water is not able to warm the stage as effective. This can result in serious internal icing of the stage if the breathing air is humid due to not properly maintained filter systems of the compressor system used filling the tanks. This fully environmental sealed design is suitable for extreme contamination, liquids other than water and Water temperatures below 4 degrees Celsius in combination with suitable air quality.

In some cases the space between the two Diaphragms is filled with oil or other liquids making the regulator incompatible with Nitrox

There is no significant performance difference between standard Diaphragm and Environmentally sealed models. Some manufacturers achieve a slightly better response to IP changes by using a thinner internal Diaphragm.

Over-Balanced Design

The goal of the so called “Over Balancing / IP Boost / Intermediate Pressure Amplification” is to reduce the breathing effort with increasing depth. It is offered by many different manufacturers.

In Diaphragm First Stages it is in general achieved by using a larger size external Diaphragm as compared to the inner one. With increasing depth and therefore increasing ambient pressure, the Intermediate pressure is artificially increased beyond the normal compensation for the depth. The result is a reduced breathing effort at recreational depth but renders the design unsuitable for technical diving as there is no limitation to the increase with increasing depth, risking failure or free-flow of the system.

 

Balanced Piston Design

The Regulators with Flow-Through-Piston Design have the highest air delivery in the market due to the large piston travel and wide, unobstracted opening of the valve assembly allowing vast amounts of air to be delivered on demand. The valve works with the “fail safe” down stream principle and there are only two moving parts in the design making it extremely reliable.

The flow-through-piston out-performs diaphragm regulators especially at low tank pressures with it’s wide opening valve assembly allowing sufficient air to flow to keep the Intermediate Pressure stable and retain performance even with more than 1 second stage in use.

As in the standard piston regulator, the water pressure acts directly onto the piston. In older designs oil or silicone grease was used to transmit the pressure. Current models allow water to enter the water chamber and different technologies are used to prevent icing of the regulator through insulation and non-stick materials.

Some models feature ribs to increase the surface and dissipate the cold more effectively enabling the use in cold-water conditions. In most cases LP-Hoses are connected to Swivels allowing flexible hose routing.

There is no depth limitation for this type of regulator as the water pressure increases the Intermediate Pressure linear.

Scubapro offered their first flow through piston design in 1964 with the MK1, followed by the MK5 in 1965 with Swivel LP-Connector
