  • mike:

    Hi, this is 2nd time i,ve turned to for solid advice.I was thinking of purchasing a mares prestige 12s regulator this year, like it,s look and features, i am a 58 year old diver and have 25 dives done in the carribean now i m back in eastern canada and will soon be diving here as well with a good dive school and club, but review of prestige 12s seem to be pro warm water ie carribean, the info i got from a dive shop here is if i am going to do wreck diving course with them they can give me the prestige 12 s however i would be possibly better off with the prestige 22 DPD which is what one dive master uses that i spoke to, have not found any other reviews so any advice what is the working range dor the 22 DPD vs 12s scuba pro mentioned 7 deg cel for 12s the other question is i like the 12s for it,s fature of more exhaust from thee side of the second stage less bubbles in view does the DPD have a similiar feature, last the dpd has a dive pre dive switch and i have to put my BCD/tank combo on in water due to a spinal surgery to prevent excess stress on my back so,i am a little occupied when i slip into the water, shoul i forget to turn the switch as i decend will i still get some air until i wake up and realize i have to open the switch and is the dpd a better choice of a reg to equal the recreational deep dives and wreck dives in the eastern canadian and american waters Once again thanks folks for being out there to ask questions to. best regards mike

    Hello Mike, if you are looking for both a warm and cold water regulator. The regulator I would suggest for you would be the Oceanic Delta 4.1 Maxflex Regulator web link: That regulator has the diver venturi which will help unwanted free flow and will give you the air you need in either positions. Plus it is design for colder water but works great in warm water. Another feature is a Diver Adjustable" Air flow which you can fine turn your breathing rate at different depth.

416155 - Prestige 22 DPD

Unbeatable safety, advanced technology, and great value

• Very easy and natural breathing
• New yoke, 15% lighter and more compact
• Dive Pre-Dive System

A modern new look for a medium-sized technopolymer second stage featuring cutting-edge technology. The special shape of the internal baffle, coupled with the VAD system, makes breathing easy and natural so it’s perfect for use at any depth.

Product Features

Dynamic Flow Control: Minimizes intermediate pressure drop during inhalation thus maximizing gas delivery, especially under extreme conditions. The DFC system (Mares patented) minimizes the pressure drop that occurs in all regulator first stages when the diver inhales. This phenomenon is even more pronounced as depth increases and when airflow demand from the regulator rises.

The DFC system is an exclusive system, unique on the market, that operates in relation to the diver's actual air demand, independent of depth and tank pressure.

The DFC system uses the Venturi Effect, optimizing the regulator's sensitivity and minimizing inhalation resistance, especially during dives in extreme conditions.

Fluid Dynamic Deflector: Receives and properly directs the airflow from the bypass tube to the mouthpiece.

Mesh Grid: Patented design which reduces the impact of water flow onto the second stage diaphragm, thus eliminating free flows even in strong currents.

Superflex Hose: Extreme light weight and exceptional softness guarantee the maximum freedom of movement.

Tri-Material Valve: Patented technology combines two grades of polyurethane on a brass core. Maximizes performance, safety and reliability.

It is composed of: a central valve body manufactured in nickel-plated brass; a highly-resistant polyurethane coating covering nearly the entire valve body that can ensure elevated resistance to wear and mechanical stresses; finally, an additional covering is applied to the surface ('head') of the valve; this covering is also polyurethane but has a softer 'modulus'(hardness) to provide a perfect seal, even under extreme conditions.

Thanks to the use of a special technology ('adhesion at the molecular level') and the characteristics of the materials used, a high level of safety (uncontrollable free flow never occurs) and reliability is guaranteed under any conditions.

Ultralight Techno Polymer: Abrasion resistant and affordable, ideal for diving in warm and moderate water temperatures.

Vortex Assisted Design: The air bypass tube conveys air to the mouthpiece creating a swirling vortex with a low pressure area in the center that keeps the diaphragm down during inhalation, for very sensitive and easy breathing at all depths.

The air coming from the LP-hose passes through the second stage control valve and is conveyed directly to the mouthpiece through the by-pass tube (Mares patented). In the mouthpiece connector, the airflow creates a swirling action, or “vortex”. The core of the vortex is a low-pressure area, which, during inhalation, helps to hold down the second stage diaphragm, thus markedly increasing regulator sensitivity. The decisive advantage of the VAD System lies in the precision of its control. The VAD supplies the inhalation effort with just the intensity required.

Another advantage of the VAD system is related to the bypass tube, through which most of the air is delivered. In cold water diving, this system prevents ice crystals (which can be generated by the expansion of humid air in cold temperatures) from interfering with the proper operation of second stage components.
