A diving regulator is a piece of equipment scuba divers can’t and shouldn’t overlook when choosing diving gear. It’s what allows divers to breathe underwater. The Apeks Flight regulator works by transferring oxygen to the diver when they’re below water. In addition to providing divers with oxygen, dive regulators regulate the rate at which oxygen flows to keep underwater divers safe.

The last thing you want as a diver is not to have enough air or feel constricted when trying to take a breath below sea-level. Therefore, choosing the best regulator is essential for ensuring this doesn’t happen.

About Dive Regulators

Dive regulators regulate oxygen intake when divers are below sea-level. There are several well-known brand-name varieties, including the Apeks Flight, for divers to consider. The regulator works by pumping oxygen through the diver’s tank to their mouthpiece. Without a regulator, divers find it challenging to take one breath at a time. Divers regulate the rate at which oxygen flows using the pressure valves on their regulator.

A Brief Review of Apeks Flight

The Apeks Flight is one of the most highly-rated dive regulators available today. The manufacturer claims it is the lightest air regulator in the world. The regulator’s construction consists of composite materials. The materials are durable and light. The Apeks Flight is a mid-range regulator. The manufacturer has tested the unit on over one million breathing cycles, guaranteeing it won’t give out on divers underwater. The Apeks Flight has also been tested for impact and fatigue, ensuring the best underwater experience.

Features of the Apeks Flight Regulator

[amazon box=”B01DHM0KQG”]

The Apeks Flight has a unique safety feature which is the first stage yoke clamp handwheel. This piece is guaranteed to prevent accidental snagging while divers are underwater. It ensures airflow won’t become constricted if the diver accidentally snags the system while diving.

With their purchase, divers receive a lightweight sports bag to carry the Apeks Flight regulator. The midweight model is highly transportable and easy to take on diving trips. It is also received the CE mark under the European Standards Test. This test ensures the regulator is efficient for diving in temperatures as low as 10 degrees Fahrenheit.

A few design features of the Apeks Flight include:

  • The anti-sag yoke handwheel clamp
  • Integrated Venturi-system
  • It is pneumatically balanced for first and second stage use
  • A robust skeletal body and in-line hose position for superior diving experiences.

How to Choose Dive Regulators

When comparing dive regulators, divers must consider several varieties. The brand-name and price are just a couple of the aspects to consider. Divers must determine if they are going to use the regulator for cold-water, warm-water, or both forms of diving. Experience level and ease of regulation are also factors divers must consider when comparing regulators. Optimal levels of oxygen flow, ability to manipulate settings, and emergency/safety features are also important aspects to think about.

Piston vs. diaphragm

Divers must determine whether they prefer a piston or diaphragm regulator. These are parts used in first stage regulators. Both of these options are for lowering pressure levels in the dive tank and are reliable for underwater diving.

The piston regulator operates in a basic manner. They can’t be overbalanced, giving them a slight performance edge over diaphragm regulators. The diaphragm regulator is more resistant to cold water diving conditions. In conditions where silt, soil, or sand is present, the regulator also outperforms piston regulators because the internal parts aren’t exposed to water like piston regulators.

DIN vs. yoke

A diver must choose between a DIN or Yoke regulator. This feature describes the fitting that divers use to attach the regulator to their dive tank. The yoke screws over the diving tank. This piece is also known as an A-Clamp.

The DIN switch, or Deutsches Institut fur Normung fitting, screws directly into the receptacle. These are more common in European countries than in other regions of the world. Both regulators are reliable and will keep underwater divers safe underwater.


Balanced vs. unbalanced

Choosing between a balanced or unbalanced regulator is another aspect a diver must consider when deciding between Apeks Flight and other regulators.

An unbalanced regulator has fewer parts than a balanced regulator. At lower tank pressure levels, it sacrifices performance at deeper depths because of this. Regulators that are unbalanced are best for shallow water dives. Beginner divers might also find these regulators a superior choice to start with when learning how the regulator operates.

The balanced regulator uses more parts in the first stage. Doing this ensures the same amount of air delivery, regardless of diving depth or pressure levels. It means air regulation is consistent in shallow waters, or for deep-sea dives. Divers have more control of oxygen intake/airflow, making balanced regulators safer for more in-depth diving excursions.

Cold vs. warm water dive regulator

Those who are deciding between warm and cold-water regulators are typically more experienced divers. Divers usually use these regulators for diving in temperatures below 50 degrees Fahrenheit.

Warm water regulators don’t have a seal. Because of this, they allow some water to seep into the system. They are usually cheaper and have a simplistic design. For shallow water dives and warmer conditions, this system is sufficient for most divers.

The cold-water system is for divers who plan on diving in frigid conditions. The main difference is that icing can occur in regulators. Therefore, these regulators contain an environmental seal which doesn’t allow contaminants to get into the regulator. It reduces the chance of icing to keep divers safe underwater.

The Apeks Flight regulator has a built-in seal making it suitable for cold and warm water diving.

High-pressure and low-pressure ports

Another aspect of the Apeks Flight and dive tank regulator is choosing between high and low-pressure ports. First stage regulators feature a port which connects other parts of the regulator. These include parts like the dive computer, gauges, and other components. This port is available in high and low-pressure varieties.

With low-pressure ports, divers can connect low-pressure items through a hose. The high-pressure port connects higher pressure items. These include pressure gauges and dive computers.

Whether or not divers choose to connect any additional items to their dive regulator, ultimately determines if they should use a high or low-pressure regulator. Those who wish to store information on dive computers or other accessories will benefit from a high-pressure port. Beginners and novice divers who are looking for something simple might choose a low-pressure port regulator.

Nitrox compatibility

Divers must also consider whether they want a regulator which is Nitrox compatible. These are for individuals who plan on engaging in Nitrox diving at any point in time. Cold-water regulators are typically compatible while warm-water regulators aren’t. The Apeks Flight is Nitrox compatible up to 40 percent.
