● Be absolutely frank to your guides regarding any health issues you may have faced or still are. They are the best persons to advise you on whether you should be attempting the sport at all or not. For instance, as mentioned above, back problems and pains inbones and joints make it risky, even impossible, for you to participate in jet-ski and bumper-boat or banana-boat rides. Similarly, breathing issues or ailments (including COVID-19) that wreak havoc on the body’s respiratory system and breathing apparatus may play spoilsport in case you want to participate in scuba diving.
● The greatest threat to any water sport is the erratic nature of ocean/sea currents, which can even be potentially fatal if one is not careful enough, says divemaster Anto of the water sports centre at Tarkarli. Before heading out, make sure to carefully consult the guides and instructors regarding the same. If you are still unsure, you may check the latest updates on the region’s weather and the prevailing sea conditions and forecasts on how these may change in the coming hours. Two other factors—tides and the season—are far less disruptive due to their more predictable natures. Water sports, at least in Konkan India, are best enjoyed in winter due to calmer seas and greater visibility. And while jet-ski and bumper-boat rides are usually organised during high tides, scuba dives happen mostly during low tides when the visibility is more.
● Water-sports organisers are not in favour of scuba diving at night time, due to the unpredictability of currents and the presence of fishing nets that prevent easy cruising on the seas. Mid-day is largely considered the best time for this activity.
● During the training session before your scuba dive in the open sea, pay close attention to and learn every aspect of the live demonstrations patiently provided by your instructor. Particular manoeuvres often turn out to be incredibly necessary. For instance, should water enter your goggles, you need to first take a deep breath through the mouthpiece of the rebreather, then tilt your head backwards—and with two fingers gently pressing your forehead, breathe out long and steady through your nose till the water in the goggles is emptied out. It is also important to keep equalising the air pressure inside and outside your ears—after every metre (or metre-and-half) of descent, remember to pinch your nose after taking a deep breath and then pop your ears. Long, deep breaths and slow exhalation are the key in the depths of the water, but if you keep hold (read: bite) the rebreather’s mouthpiece too firmly, you may end up with an ache in your jaw and end up letting go of it—a scenario akin to abandoning your life support. The instructors will tell you that it is important to hold the respirator in your mouth with just the right amount of pressure. Make sure to retain an 'O' shape in your mouth throughout your adventure—any attempt at smiling or moving your facial muscles is likely to result in water flooding into the mouthpiece of the rebreather. Make sure that the guiding team double-checks every piece of your scuba equipment, especially the level of gas in your diving cylinder and the potential presence of leaks and malfunctions in the equipment. Usually, a single scuba dive ends up using half of the volume of gas in the cylinder. Lastly, remember the gestures that are shown and taught to you. Each of them are vital in communicating your state to your guide during the dive, and are especially critical if you wish to convey that things are not okay. Remember—you cannot speak a single word during your scuba dive, neither can your words be heard if you are attempting to do so, should you be in a state of panic.
● I know this is easier said than done, but do not panic in case of any adverse situation. Instead of instinctively reacting (like I had done), keep your wits about you, and employ the contingency measures you have been taught. If you are still struggling, make sure to communicate to your guide using the correct gestures that things have taken a turn for the worse. Remember, experienced divemasters or guides are there for you every inch of the dive, and they keep continuously communicating with you to keep checks on your state and to remind you of the things you need to be doing at regular intervals. Under the sea, your life is as much their responsibility as your own.
