Diving Compressors – What They Are And Why You Need Them

A diving compressor is an air compressor that provides breathing-quality air to a diver. This can be done by filling diving cylinders (tanks) or by providing constant air at the surface. Compression condenses the breathing gas, removing the water and allowing a certain volume of gas to be contained or stored.

Diving compressors are large three or four stage reciprocating air compressors. They can use oil or some have ceramic lined cylinders with O rings so that no lubrication is needed. Those that use oil must only be lubricated with the oil specified by the manufacturer. Filters are installed to remove water and oil residue. Be aware that just because an air compressor is oil-free it does not mean the gas output will be of breathable quality.

A diving compressor will meet certain criteria- including air quality. They operate at much higher volumes than the standard garage’s air compressor. Compressors used to fill cylinders must provide high pressure and low volume whereas compressors used at the surface will provide low pressure but high volumes of breathing gas because they are normally supplying more than one diver with air.

Those looking to purchase a diving compressor should be trained and certified in inspecting scuba equipment. Being a Professional Scuba Inspector (PSI) means the diver will know how to safely fill and inspect a diving cylinder. Incorrect procedures can mean life or death in the waters.

A certified inspector will first make sure the cylinder is in compliance (meaning it has been recently tested.) They will then remove or bleed out air until the tank is at five or ten pounds PSI- a tank should never be fully emptied. With the tank mostly empty the inspector will shake the tank, checking for loose objects or water.

The inspector will then examine the valve- looking for rust or damage. Then he will begin to fill the tank. The cylinder will be placed in a cool bath and filled slowly (at less than one bar per minute.) This is to prevent the cylinder from becoming heated, which can cause an unsafe reduction of pressure in the tank when cooled.

Some diving compressors come with a bank. Compressors used to fill dive cylinders may have a bank that will fill storage tanks when it is at idle. Surface supplied compressors will have a bank filled with back up breathing gas in case of mechanical failure.

As stated above, compressors remove water from the gas, which is good for the dive cylinder because it prevents the formation of rust. It will also prevent the regulator from freezing. This, however, does make the air very dry, leaving divers at greater risk for dehydration. It’s crucial to make sure the divers are adequately hydrated before and after the dive to prevent decompression sickness.

Decompression sickness occurs when a diver ascends too rapidly, and the body becomes overly saturated with nitrogen. Decompression sickness can be fatal if severe. Along with making sure they are hydrated divers should make sure to complete several decompression stops on their way back up from a dive.

Diving compressors are an important part of the safety of scuba diving. Therefore, it’s very important to make sure cylinders are properly filled and inspected by certified divers. Those looking to own a diving compressor themselves should be aware that the equipment is an investment and know how to properly care for and use the compressor. A diving compressor will be the most expensive piece of equipment a diver can own, so it is often only purchased by those looking to open their own dive shops or scuba tours.

Why You Need Diving Weights

Diving weights are used to ensure that a diver has zero buoyancy. This is a critical aspect of diving, because if a diver does not have a zero, or neutral buoyancy, they will need to expend effort just to remain in place. This will cause a diver to tire more quickly and need to leave the water sooner than would otherwise be necessary.

Contrary to the perfectly normal fear of drowning, a human being does not sink in water. We are naturally lighter than water, and as long as we don’t fill our lungs with it, we will float in the water. Loading ourselves up with gear might seem to counteract that and cause us to sink, until you stop to remember than we have a tank full of air strapped to our backs. This causes us to be buoyant, which is where diving weights come in. Buoyancy is calculated by the weight versus the amount of water displaced. If you weigh less than the water you would move out of the way, you float. If you weigh less, you sink.

The diving weights are usually small lead weights that can be placed within a diving belt to add a little more weight to a diver. This is usually done little by little, until neutral buoyancy is achieved. Until that happens, a diver must constantly be swimming down in order to avoid floating back to the surface. Thankfully it doesn’t take a deep immersion to figure out whether or not a diver is at a neutral buoyancy, if they can sit a few feet below the surface without moving, and not rise or sink, then they are good to go.

Freestyle Men’s FS81324 Hammerhead XL Stainless Steel Watch Review

Having a water-proof watch with you while scuba diving is a convenient way to keep track of your time underwater, and more importantly, helps you manage your air supply in a more efficient manner.

The Freestyle Men’s FS81324 “Hammerhead XL” Stainless Steel Watch is a great dive watch with an easily readable display, and extra large buttons which are easy to operate even with dive gloves on.

A lot of the customer reviews of this product say the same thing; namely that the watch looks even better in person than it does in the advertiser’s image. Many people report liking the style so much that they simply wear this watch all the time, not only while diving.

This watch also features a tide table dial which is a cool addition not only for divers, but surfers as well! The old school analog display is a nice departure from the standard digital display you’ll find on most dive watches today, and the whole color scheme of the watch just “works” in both a functional and aesthetically pleasing way.

So if you’re looking for an attractive way to keep track of your time under the water, or simply want a good water-proof watch for a day of body boarding at the beach, the Freestyle Men’s FS81324 “Hammerhead XL” Stainless Steel Watch is an attractive analog take on the modern dive watch.

OTS Guardian Full Face Mask Review

The OTS Guardian Full Face Mask is a remarkable piece of diving equipment, known for its good performance in cold water diving situations (including ice diving). This mask rarely fogs and will almost never freeze. It comes standard with an ambient breathing valve to help you preserve your tank while above the surface, and also features a double seal to accommodate various face sizes and shapes.

The OTS Guardian Full Face Mask has a wide viewport which offers outstanding visibility. The mask comes with its own special storage bag which is ventilated to make sure it gets as dry as possible between uses. It’s been reported that the mask seals best for bare skin, but can work properly with thin latex hoods as well (although it may become harder to clear your ears when using a hood).

The only downsides to the OTS Guardian Full Face Mask are the standard downsides that come with using any full face mask, namely the special drills and procedures you must be familiar with in the event you have an equipment failure or OOA incident. Because of this it’s recommended that you always bring a regular mask as a back up in case you have to hook up to either your own, or your buddies’ backup octopus.

Of course the OTS Guardian Full Face Mask also has all the perks that a full face mask offers; allowing nasal breathing which helps prevent dry throat, the ability to talk, and more importantly – added safety in situations where the diver loses consciousness (divers in full face masks are much more likely to stay connected to their air supply than a those with standard regulator).

The mask also comes with a set of nose blocks which should fit almost anyone.

The OTS Guardian Full Face Mask comes in 7 different color combinations:

  • Blue / Black (Area inside the faceplate is blue)
  • Black / Blue (Area inside the faceplate is black)
  • Black / Pink
  • Black / Green
  • Black / Red
  • Yellow / Black
  • Solid Black

The OTS Guardian Full Face Mask is a great pick for any dive, but has gotten its best reviews from people who enjoy the thrill and the chill that comes with diving at very low temperatures.

ScubaPro Jet Sport Fins Review

The “ScubaPro Jet Sport Fins, Scuba Pro Diving Fin” is a longer version of the traditional Jet Fin. “Jet Fins” are a child of the old-school 1960’s style of innovation; the kind that eventually took us to the moon and back. The idea behind them is not too hard to wrap your head around.

The fins have 3 channels that run along the underside of the fin (the part which would touch the ground if you were standing on land), and a group of vent holes below (and connected to) the channels.

What this does is allow water to flow through the fin as you go through your stroke. It minimizes the drag during your upstroke, and maximizes your propulsive force during the downstroke; a truly ingenious way of streamlining the way we use our feet to propel ourselves through the water.

“Jet Fin” is actually a very accurate description of the concept, because it truly does utilize the same principle as a jet engine; which is to reduce the resistance to flow on intake, and maximize fluid flow as the fluid leaves the system.

Hopefully, I didn’t lose half of the audience with that history/physics lesson. Let’s move on to what makes these fins better than most other Jet Fins on the market.

Firstly; the increased length of the fins makes a noticeable difference. In an ideal world, longer fins are always better (when it comes to propulsion, not ease of use). These Jet Fins split the middle between long (non-jet) dive fins and your traditional 14” Jet Fin model.

And the result is just that: A middle of the road fin that offers satisfactory speed, but isn’t as heavy as a full 24-28” dive fin. If you’re looking for a great addition to your current selection of dive gear, the “ScubaPro Jet Sport Fins, Scuba Pro Diving Fin” is hard to beat.

Best Snorkel Masks of 2019 Review
