Cold Water Regulator Buyer’s Guide
Knowing all the best selling and quality cold water regulators is no enough. To figure out what’s best for you, it’s also mandatory to understand the features. In this buying guide, you’ll learn all the features that ensure a good-quality cold water regulator.
Several regulators are apt for cold climate diving. If you play to dive in icy or extremely cold conditions, you should choose a regulator restricting freezing and freeflow. The good news is that the cold water regulators also work well for tropical climates.
If you are considering buying cold water regulators adequate for dive travel, we have good news. In the current day, there are plenty of models that weigh as little as 2.5 lbs. Generally, most travel regulators use carbon fiber and titanium to reduce overall weight.
However, these are not the ideal material to sustain cold waters. If you want a quality cold water regulator, look for a regulator which equips insulating and sturdy metals like nickel or brass.
Even if you choose a light-weight model, it should not feel flimsy. Durability and weight are very critical if you are venturing in a freezing climate.
Balanced or Unbalanced
In short, if you will use the regulator for cold water diving, better go for a balanced regulator. The difference between a balanced or an unbalanced regulator is the way they breathe.
The balanced regs will offer the same air amount per breath until the tank is empty. On the flip side, it is challenging to breathe from unbalanced regulators when your tank is low on air.
This flow change is an excellent reminder to check the pressure gauge and prevent air emergencies. However, for cold waters, a dramatic shift of flow is risky and impractical. It is also worth mentioning that balanced regs are better for deep diving.
Piston or Diaphragm
The main difference between piston and diaphragm is the method why which you consume the air. Gas from your tank passes into the regs first stage, where it may force a diaphragm or a piston to open and shut with each breath.
Piston first stages have a higher flow rate and allow easier breathing. The diaphragm offers a lower flow rate which disables freeflow. However, the divers might find the diaphragm first stage to be challenging to breathe.
Always opt for an environmentally-sealed diaphragm. The environmentally-sealed diaphragm does not freeze quickly.
Number of Ports
If you dive in cold or warm waters, you’ll need more ports on your regulator’s first stage. Most regulators include one high-pressure port for computers with wireless transmitters or pressure gauges.
Additionally, they’ll also have four low-pressure ports for dry suits, BCD inflator hoses, and second stages. However, if you are diving in cold waters, five ports will not be adequate. Many cold-water divers use several gauges for redundancy.
Also, for some climates, a drysuit is essential. It is not possible to add extra ports to your regs first stage. Therefore, choose a model with more ports.
Diving in cold water or ice diving is a thrilling experience. However, if you wish to enjoy your cold diving time to the fullest, it’s better to get a cold water regulator. A cold water regulator can come in handy in various situations.
When you are picking a cold water regulator, make sure to consider your preferences as well. All of the cold water regulators on our list have pretty positive user reviews. We hope that this review and buyer’s guide helped you pick the perfect gear.
Best of luck with your cold diving experience!
