Divers must return to the surface in carefully monitored stages, usually following the speed of their air bubbles, so as to control the rate at which this absorbed nitrogen is released. Depending on the amount of nitrogen absorbed and the rate at which it was released, a case of the bends can range from aching joints or a skin rash to paralysis and death.

Another nitrogen-related danger is the narcotic effect of all that extra nitrogen in the body. Anyone who has had nitrous-oxide gas at the dentist is already familiar with this effect. Nitrogen narcosis is a danger because it impairs judgment and sensory perception. As with the bends, the degree of nitrogen narcosis is related to how deep a diver goes and how much nitrogen they absorb.

Oxygen toxicity is usually a problem only encountered by deep divers who go below feet. Like nitrogen, the body absorbs extra oxygen under increased underwater pressure as well. For most divers this is not a problem, but at extreme depths so much extra oxygen is absorbed that this life-giving gas becomes toxic.

The effects include tunnel vision, nausea, twitching, loss of consciousness and seizures. Another risk facing a diver who rapidly ascends to the surface is pulmonary embolism. The Pro saves to a computer by a USB cable, the plus by a cabled Bluetooth connection to a smartphone.

The dive computer will store 36 hours of logs with a 5-second profile. The Puck Pro Plus is an entry-level, large wrist dive computer. However, it does have a gas switching ability making it suitable for some types of technical diving as well. The display is one of the easiest to read of any dive computer on the market. The batteries are expected to last about dives and can be changed by the user.

While diving, we always want to control our buoyancy. In the water column, we strive to become neutral buoyancy, meaning we neither float up nor sink.

We move up or down based on our body position and leg action. However, as we move deeper or shallower and as we use the air in our tanks, our buoyancy changes. Also, we will use the BCD to provide positive buoyancy after our dive, so we can comfortably float on the surface.

The BCD is also the means we carry our air supply in a tank. A secondary function of the BCD is to help us stow our equipment. These are attached to the BCD. Some BCDs come with a weight integration system to remove the need for a separate weight belt. A regulator controls the release of the air in your dive tanks. It has two portions connected by a hose.

The first stage attaches to the scuba tank. It reduces the high pressure in the tank to an intermediate pressure. The first stage has a mix of high-pressure and low-pressure ports.

The high-pressure ports are used to measure the pressure remaining in the tank, while the low-pressure is used by the second stage and other low-pressure devices. The second stage is attached to the first stage by a hose. The second stage takes the air at the intermediate pressure and lowers it to the surrounding pressure. The second stage has a mouthpiece that you put in your mouth. This is the air you will breathe. The octopus is a backup second-stage regulator. It also attaches to a port on the first stage.

If the primary second stage fails, a diver can switch to the octopus. Second-stage failures are very rare. However, the octopus is also seen as a sharing device. If your dive buddy runs low on air, you can share yours. Dive computers are very popular. They have in many cases replaced the need for dive tables while planning your dives.

They make real-time evaluations concerning your dive times and the risk of the bends, then inform the diver of the remaining dive time and the need for safety stops. They are also capable of recording the depth, time, and even the water temperature so you can review them later. Dive computers replace the need for a depth gauge and air-integrated ones can replace the SPG.

Consider getting one with your package, it can reduce or eliminate the expense of the gauges. The scuba diving packages put together the items that you will need as you move away from rental gear to owning all of your own. Like the combo meal at your fast food restaurant, getting the items as a package will normally have some savings. Most scuba gear packages will include the BCD, regulator, octopus, and a gauge console.

However, as the dive computer is becoming more than a common accessory to a required item, many packages include the dive computer in the console replacing the depth gauge. Your mask, fins, and wetsuit are not a part of packages as these items are often purchased during your training.

Related Review: Dive Safety Gear. Scuba diving is a very safe sport, provided that you have been properly trained. Before you go scuba diving, you must receive training and become certified. The type of scuba diving gear you choose to purchase will depend mostly on the location where you plan on diving. Warmer climates generally require less dive gear than colder climates. Commonly we refer to diving conditions into separate categories that each require a different set of gear:.

This includes a thin wetsuit or no suit at all. You will likely not need a thick wetsuit but one that varies depending on temperature. Having a suit around mm is ideal for these temperate environments.

Depending on how cold your climate is, a wetsuit may not do it. You may need to opt for a dry suit. Also, at these water temperatures, you will need regulators that are designed for the colder water.

Similar to the problem of icing on a plane's wing, a regulator can build up ice even when the water temperature is above freezing. Scuba diving gear packages are a great way to get everything you need for your dive in one convenient place.

It can be daunting to buy all the different components you will need for your dive. Opting for a full scuba gear package will ensure all your dive gear works well together and will allow you to get the most from your purchase. Did you invest in a scuba gear package?

This part of the scuba octopus setup works exactly the same way as the primary second stage. While it consists of the same parts, it is connected by a low pressure hose. An LP hose transports the intermediate air from the first to the second stage. An alternate second stage LP hose is usually longer for ease of use by another diver if needed. A high pressure HP hose connects this pressure gauge to the first stage in the regulator.

This hose sends HP air directly from the tank to the gauge. The gauge console also houses other useful gauges, such as a dive computer, depth gauge or compass. The buoyancy compensator BC inflator is fed intermediate pressure air from the regulator first stage through this LP inflator hose. This gives the diver the opportunity to add air to their BC directly from tank when they want to.

Where the low-pressure inflator hose attaches to the buoyancy compensator inflation mechanism, a sleeve is used. This metallic sleeve needs to be held back when connecting the hose to the BC inflator. They are usually textured for easier grip in the water. The attachment opening connects the BC inflator to the LP hose.

These come in a variety of sizes. Scuba tanks are filled with compressed air at an extremely high pressure. Trying to breathe directly from this is not possible, and would result in injury. The scuba octopus setup, or regulator, reduces the pressure of this compressed air to an ambient pressure that the diver can safely breathe.

This is achieved by the air traveling through a series of hoses and valves. The regulator then sends this breathable air to the diver. The scuba octopus setup works with two main stages: first stage pressure reduction and second stage pressure reduction. It is important to understand the difference between these two stages, and which valves and hoses work to control them.

Keep reading to find out more! This initial stage of pressure reduction takes the super high-pressure air or breathing gas from the tank, and lowers it to an intermediate pressure. This is the first step in creating breathable air, and it is achieved through a few parts. When looking at a typical open water style regulator, the first stage connects to four different hoses. One of these channels the high-pressure air directly from the tank and into a submersible pressure gauge.

The other three hoses channel the intermediate pressure air to the second stage, and to the buoyancy compensator BC inflator. In the second stage, the intermediate pressure from the first stage is lowered to an ambient pressure. The ambient pressure matches the pressure of the water surrounding you, and this is what is safe for the diver to breathe. This is achieved through the pressurised air traveling through a regulator hose, which then gives the diver access to breathe from.

The second stage can be broken into a primary second stage and an alternate second stage. These are the same thing really, except that the alternate second stage acts as a kind of emergency air source to those who may have run out of air or in an emergency. Scuba octopus setups are complex but reliable mechanisms. The scuba octopus setup should definitely give you years of good use. Any local dive center should be able to take your dive gear in for all necessary services.
