AS a diver,the wetsuit is a suit that is a must, regardless of where you may be diving .Apart from keeping the diver warm ,it also afford protection from cuts and scrapes from corals or other sharp objects that can cause nasty infections. The scuba diving wetsuit is available in a variety of forms, types and options. For extreme cold environments.There is the dry suit, where thermal protection worn underneath the waterproof suit helps the diver stay warmer when diving in near freezing waters.
Alternatively,in warmer waters, a full length suit or a shorty suit will be adequate . Even temperate waters causes the body to lose heat quite rapidly because
water is a very efficient conductor of heat and if the divers body is not insulated,body heat is conducted away more rapidly in comparison to a dry environment and may force you to cut your dive short,due to body's core temperature dropping so fast,the diver starts shivering and in effect spoiling the fun of diving .
The average human body maintains the optimal body temperature around the core or torso area where all the main and vital organs are at.Heat needs to be maintained around this area, only then temperatures around the extremities of the arms, hands, legs and feetcan be kept constant. A full wetsuit enables the diver to maintain a more even distribution of body temperature to the extremities.
Ideally suited for slightly colder waters, whilst the shorty wetsuit with a thickness of 2 - 4 mm is quite adequate for the warmer tropical waters, when
A lot of divers prefer the shorty wetsuit, beacause of the flexibility of movement it allows than the full length one, or what is more commonly refered to as the steamer suit, but it all boils down to personal choice,and what makes the diver more comfortable.And also,the environment which the diver more often ventures into ,determines the choice of suit they 'd prefer to have.
IF the diver regularly dives in a variety of different locations, theres is the detachable wetsuit which is a strong contender for selection.This is a typically full sized suit, with detachable arms and legs, which can convert into a shorty type suit. You could detach the legs and leave the arms on or vice versa, and effectively have a ubiquitous all condition suit , and in line with your preferences too.
Always remember wetsuits also gives protection when diving, from both stings,cuts or scrapes that may be caused by diving around coral and sharp edges of wrecks or rocks, which also explains the preference for the full sized suit, to afford them that protection. Not to mention the harmful UV rays of the sun.
If picking up the activity of scuba diving nthen investment in wetsuit can be quite significant depending on what type you opt for, as well as what sort of conditions you most frequently dive in; therefore you should either select a suit that caters for the majority of your dives or even consider the detachable option which gives you so much more flexibility when diving in different conditions and under a variety of differing situations.
Generally ,thickness of the suit selected is based on the environment the diver most often will be exposed to.
TRopical waters usually range from 25 degrees to 30 degrees celcius plus so a shorty or fullsuit of 3mm is suitable.Anything cooler than 25 degrees celcius means that if unprotected the diver will get hyporthermic very rapidly and if the insulation wasnt enough
then getting chilled or starting to shiver comes very fast so it will be more advisable to have at least a full suit 5mm in thickness.Thickest wetsuit comes at 7mm and thermal insulation for waters as cold as 15 degrees.
Any colder and the dry suit is next in line.
