Your diving equipment is not going to be a small financial investment. For beginners, a trip to the local scuba dive shop can be an informative place to start with regard to learning about what equipment you need.

Masks can run anywhere from $20 to $150. You’ll have to consider construction, size and lens. Low-volume masks provide divers with less distortion, as well as more light transmission and peripheral vision.

A double-flanged face seal is a nice variation that ensures your mask remains watertight. Other options for this diving equipment include: anti-fogging, purge valves (to keep water out), nose pockets and adjustable straps.

Fins can be as little as $30 or as much as $200. Length, material and design will all need to be taken into consideration.

Different design variations include split fins, force fins, self-adjusting pivotal blades and vents. This piece of diving equipment is crucial because choosing the proper scuba fins can save energy, air and unnecessary hassle.

Regulators are among the most expensive diving equipment, running from $150 to $500. The main reason we buy this piece of diving equipment is to ensure proper air flow in any condition with the least amount of effort on our part.

As you descend deeper, remember that the air will get heavier and more difficult to move from the tank to you, so a good regulator will deal with this physics problem effectively.

Experienced divers recommend regulators with swivels and adjustable airflow stages, such as the Aqualung Legend LX or Oceanic Delta 3. Warranties are important, so consider brands with lifetime warranties.

Divers in warm coastal waters may choose thin, clingy wet suits that allow water to seep next to the body and keep divers warm. They can choose between short, long or overall styles. Cold water divers (in waters 60 degrees or less) will want more heavy duty dry suits.

Looser dry suits can be made out of several different kinds of material: neoprene, membrane or a hybrid of the two. A proper body suit is one of the most important pieces of diving equipment, because the comfort of your trip depends upon a good style and fit.

Buoyancy Compensators can also run $150 to $500. The most important factor here is the fit. You can choose back-mounted, flow-through or wrap-around diving equipment.

Female divers will be happy to know that the Oceanic Isla, Seaquest Diva and Scubapro Ladyhawk are all BCs made exclusively for women, with shorter waists and more comfortable chest straps. Most divers won’t need to worry about purchasing extra lift capacity, unless they’re diving in rough waters.

Hefty tanks will set you back $100 to $400. Aluminum tanks are widely used for their light weight; however, some people still prefer steel. Neutrally buoyant tanks are widely recommended by professionals.

Lighting systems range from $30 for the most basic incandescent hand light to $800 for a professional HID torch system. Cave and wreck divers or night divers will especially need to look into this piece of diving equipment.

Safety recommendations require that every cave diver have three separate light sources present — one main and two backups. A wide-beamed primary light will illuminate a large area and is ideal for overcoming total darkness, while a brighter, smaller secondary light will reveal coral crevices and nooks.

Each year, you should take your diving equipment to the dive shop for its annual tune up. This is especially important for BCs and gauges. Rinse all scuba gear with fresh water, dry in the sun and store them in a cool dry place.

It’s not unusual to have scuba equipment for thirty or forty years. While you may feel comfortable renting, you might be more inclined to participate in more outings if you’ve purchased the gear yourself.

Finding a mask that fits your face well is a simple matter and can be tested with the following three-step procedure:

1. Place the mask on your face but with the strap placed out of the way. 2. Inhale slightly through the nose so that the slight vacuum holds the mask on your face. 3. Test the fit by gently moving your head and it should remain in place if you gently try and pull it away from your face.

At the end of this test you will have determined whether a scuba mask fits your face well or not, so now it is time to examine other features.

Style : The style of mask is now usual and features a pocket for the nose that protrudes forward of the lenses and as well as low volume the large lenses allow for a wider field of view, but models to look for include Cressi Big-Eyes, although it is not suitable for all face shapes.

Colour : This is purely a matter of personal preference and you may not have any preference at all. The traditional colour for masks, and all dive equipment in fact, was black due to the use of neoprene. These days silicone is used instead for masks, which is more flexible and less susceptible to sun damage. Silicone can be supplied transparent or in a multitude of shades due to the use of colouring agents, but many people still choose black. However, some people claim masks made with transparent silicone give better visibility due to the greater amount of light allowed to enter.

Skirt : High quality scuba masks feature a silicone skirt that thins towards the edge, allowing for a better and more comfortable fit against the skin of the face. Often you’ll see a second skirt inside the upper edge of the skirt that allows a better seal. Its absence at the bottom is to allow water to drain more easily from inside the mask.

Strap : There are many occasions when you’ll need to adjust your mask strap and so ensure that you find the mask easy to adjust. If you wear gloves when diving then make sure you can adjust it quickly and easily with gloves on. And while on the subject of mask straps, remember to always carry a spare – it is one of the more common equipment failures and the lack of a spare may mean you have to remain on the boat when everyone else is enjoying the submarine world.

Those are the most important factors to consider both when buying a new scuba mask or using rental equipment from a dive centre. By ensuring a good fit you ensure your own comfort and safety while a combination of the other factors will mean you get many happy years of service from your scuba mask.
