Enthusiast and hobbyists pursuit the sport of scuba diving to either observe the beauty of underwater flora and fauna, to fulfill advocacies geared towards marine life protection or simply to experience the thrill of diving into recreational depths. For whatever interest recreational divers may have for the sport, particular guidelines must be observed not only to increase the diver's margin of safety but also to heighten the pleasure available from this popular diversion. Below is a rundown of 5 'don't do' tips that a scuba diver shouldn't miss.
Do not dive when your airways are congested.
The tell tale signs of an upcoming cold, cough or flu should convince you to postpone your dive until such time that your airways become decongested of mucus. Many novice divers succumb to ear barotrauma due to the improper application of middle ear equalization techniques in the encounter of rising pressure at descent. Consequently, an upper respiratory infection doubles the risk with the condition's likelihood to block the eustachian tube (the auditory tube linking the pharynx and the middle ear) and trigger middle ear squeezes. Middle ear squeezes can progress to ear barotrauma that often results to lung injury and damaged bodily tissues.
Do not drink alcohol before the dive.
Popularly referred to as 'the Martini effect', Nitrogen narcosis is imminent in the use of Nitrogen-based gases where the condition usually manifests in depths of over 100 feet; affecting diver cognition and response. The risk of intoxication is severed for divers who drink alcoholic beverages at least 24 hours before the dive. As much as possible, abstain from alcohol a few weeks before your planned diving trip.
Do not Overweight.
Many divers think that by strapping more lead weights onto their belt or by the legs could enhance buoyancy control; particularly for divers who often encounter problems during descent. Nonetheless, this practice will not only prove to be exhausting but also increases the inhalation effort of the diver which prevents the optimal use of his limited air supply. This results to limited bottom times and a weary diver. Before you dive, master pertinent buoyancy techniques and scuba equipment operation in the swimming pool and get rid of the heavy weights.
Do not dive in unknown waters.
Conduct prior research of the dive site's profile before engaging in any dive. Better yet, consult a local diver for pertinent information so that you won't be caught unprepared in the encounter of strong underwater currents, natural obstructions and possible attacks from marine animals. If conducting a night dive, be sure to perform a preliminary dive of the site during daytime.
