How do I choose a scuba regulator?
So if you’re planning on diving in colder waters then you need a bigger first stage with heat exchange fins smaller lighter regulators sacrifice cold water performance from weight.
How long are scuba regulators good for?
The regulator you buy today could last 15 years or more, so preparing for your future diving is just as important as preparing for your current diving.
What is the difference between 1st stage and 2nd stage regulators?
Single-stage gas pressure regulators reduce cylinder pressure to delivery or outlet pressure in one step. Two-stage gas pressure regulators reduce cylinder pressure in two steps.
Can a scuba regulator fail?
Comment. Scuba regulators work on a “downstream” principle, where the air flows down from a high pressure to an intermediate pressure and then down to a low pressure. Because of this they are often thought of as “fail safe” because many failures will cause a free-flow of air rather than cut off the air supply.
Is DIN or yoke better?
A DIN first stage is considerably less bulky than a yoke and is overall more streamlined, with less risk of it snagging on anything. This is advantageous if you ever end up diving in any overhead environments such as wrecks, caverns or caves, which brings us nicely onto our next point…
Do I need an environmentally sealed regulator?
If you are diving in cold water, a regulator with an environmental seal is a must. Without you can end up with icing in the first stage and end up with a free-flowing regulator. If you are diving on water temperature above about 12ºC then you will not need an environmental seal.
How often should I service my regulator?
Most regulators require a service every 12 months or 100 dives, but how many of you actually consider this every year. If you don’t service your car regularly it can become a real inconvenience, stuck on the side of a rainy, windy road waiting for a mechanic or tow truck to come and rescue you.
How do you maintain a regulator?
How to Store Your Regulators
- Wash Them Thoroughly.
- Keep Them Dry.
- Keep Them Flat.
- Keep Them in the Dark.
- Don’t Store Them for Long.
- Take The Pressure Off.
Do I need a 2 stage regulator?
If a first stage regulator is used in an LP Gas plumbing system, a second stage regulator must be installed downstream. In other words, a first stage regulator can’t be installed independently in an LP Gas system. There must be a second stage regulator installed as well.
Which is better piston or diaphragm regulator?
Those who prefer piston regulators claim they are a better value for their money than any diaphragm product. Other divers swear by diaphragm regulators, finding them to be superior in terms of all the above-stated advantages.
Why do scuba divers have two regulators?
Regulators deliver air to the diver by using two separate “stages” to reduce the high pressure of the air from the tank. Both stages working together make it possible for the diver to get air delivered at a pressure that is comfortable for breathing.
Should I keep air in my scuba cylinder?
Never Store Your Scuba Cylinder Empty
Your scuba cylinder should always be stored with a minimum of 200 psi inside of it. If it is stored completely empty, the absence of pressure inside the cylinder can allow all sorts of things to enter into it. Most divers don’t think much in the way of their scuba cylinders.
Do you adjust buoyancy frequently while diving?
While diving, it is not necessary to constantly use your BCD for controlling your buoyancy. The best way to control your position in the water by breathing in and out.
What should I look for in a regulator?
What To Look For When Buying A Regulator | Scuba Advice – YouTube

Can I service my own regulator?
Many divers with no formal factory training successfully service their own regs. BUT they do so after getting some kind of education on just how regulators work, how they are designed, and knowing what tools to get. And then you have to get the parts. For some models it’s easy.
When should a scuba regulator be serviced?
Most brands of regulators require service if the regulator has been sitting unused for longer than 6 months, Atomic does not. Brands of regulators that require service every 2 years / 200 dives or longer: Atomic.
What happens if water gets in your regulator?
The internal parts are vulnerable to damage when they’re exposed to water and moisture, so letting them get soaked will probably end up causing you to have to take your regulator to a professional to get fixed. Prior to rinsing off your regulator, replace the dust cap, securely fastening it on.
What is the advantage of a two stage regulator?
Two-stage regulators are designed to lower the high pressure in two stages. They require less readjustment and provide a more constant delivery pressure despite changes in inlet pressure. They are exceptionally well suited for high pressure cylinder applications.
What could be the major disadvantage of a single stage regulators?
The downside is Single Stage Regulators have a less stable output, especially at low pressure settings. Where Single Stage Regulators are used for high output applications, it will be necessary to adjust the pressure from time to time. This is because as the cylinder pressure drops, the output pressure will creep up.
What is the difference between a balanced and unbalanced regulator?
Balanced/Unbalanced Regulators
A balanced first stage regulator offers consistent air flow regardless of depth and tank pressure. An unbalanced regulator will become harder to breathe from as depth increases and or tank pressure decreases.
What is piston type regulator?
Oxygen regulator is a decompression device for cylinder oxygen, which ensures that the export pressure remains stable when the import pressure and the outlet flow change. Mainly used in clinical and home oxygen-absorbing therapy.
What happens if you throw up while scuba diving?
The vomit will be forced out the regulator in the same way your exhaled breath is. Nothing will get into your air supply because air does not flow back into your cylinder.
What is the most important feature of a scuba regulator?
Ease of breathing – The best regulator is one that makes breathing as easy underwater as it is on the surface regardless of depth or conditions.
Is it OK to leave scuba tanks full?
Do not store tanks that are full of air for prolonged periods of time (no more than 3 months. A tank should be stored with just enough pressure (200 psi) to keep moisture out. Remember the higher the tank pressure, the greater the corrosion that may form inside.
