In the world of scuba diving, many divers spend a lot of time focusing on the excitement of what happens during<\/em> the dive: the marine life, the buoyancy control, the navigation, or that picture-perfect wreck lying silently on the ocean floor. However, one of the most important\u2014and often overlooked\u2014parts of every dive begins before you even get there: the descent. Whether you\u2019re diving in a swimming pool for a confined water session or descending into the blue on a fun dive or advanced course, how<\/em> you descend can make all the difference.<\/p>\n\n\n\n At Oceans 5 Gili Air, An SSI Instructor Training Center on Gili Air<\/a>, the emphasis is always on a slow and controlled descent<\/em>. From the first moments of the SSI Open Water Course to the most advanced technical dives, students, interns, and even fun divers are reminded to take their time on the way down. Why? Because safety, ear health, and dive comfort start from the very top of your dive.<\/p>\n\n\n\n Before we dive into the why, let\u2019s quickly cover the what. When you begin your descent, the pressure around you increases. At sea level, we experience 1 atmosphere (ATA) of pressure. For every 10 meters of depth, another atmosphere of pressure is added. As the pressure increases, air spaces in your body\u2014particularly your middle ears and sinuses\u2014must equalize to match the surrounding pressure.<\/p>\n\n\n\n This process is natural but not automatic. Divers have to actively equalize their ears by techniques like swallowing, wiggling their jaws, or using the Valsalva maneuver (gently blowing against pinched nostrils). If the descent is too fast or uncontrolled, the pressure can increase faster than your body can equalize, resulting in discomfort, barotrauma, or even serious ear injuries such as eardrum rupture.<\/p>\n\n\n\n At Oceans 5 Gili Air, the teaching team emphasizes a golden rule: \u201cThere is no need to rush to the bottom.\u201d<\/em> Every instructor, divemaster, and assistant is trained to teach and demonstrate slow and controlled descents, regardless of the dive site or dive level. Before every pool session or ocean dive, instructors take time to brief their students clearly on the importance of descending slowly and equalizing early and often.<\/p>\n\n\n\n Students are encouraged to listen to their bodies and communicate if something doesn\u2019t feel right. They\u2019re reminded that descending is not a race; it\u2019s a critical transition phase where safety and comfort must take priority.<\/p>\n\n\n\n Many divers think of equalization and controlled descents as something they only need to worry about during their SSI Open Water Course. But that couldn\u2019t be further from the truth. Every diver, from beginner to professional, should approach the descent with the same care and attention.<\/p>\n\n\n\n For brand new divers<\/a>, a slow descent sets the tone for good diving habits. It\u2019s also the most vulnerable stage of their diving education. Ears are not yet conditioned to frequent pressure changes, and students are still learning how to manage buoyancy and underwater orientation. At Oceans 5 Gili Air, instructors spend time in the pool teaching students to equalize in shallow water and control their descent using their inflator and breathing. By the time students get to the ocean, they\u2019re already familiar with the idea that slow is safe<\/em>.<\/p>\n\n\n\n Even experienced divers<\/a> can experience ear issues if they rush the descent. During deep dives, wreck penetrations, or drift dives where currents are involved, the temptation to descend quickly and \u201cget into position\u201d is common. However, skipping the basics can lead to discomfort or injuries that could have been prevented.<\/p>\n\n\n\n In the Advanced Open Water Course at Oceans 5, instructors make it clear: you must always<\/em> equalize, no matter how many dives you\u2019ve done. Specialty courses like Deep Diver, Wreck Diver, or Drift Diver all include review of descent techniques, especially because descents in these conditions can be more challenging due to depth, visibility, or movement in the water.<\/p>\n\n\n\nUnderstanding What Happens During a Descent<\/h3>\n\n\n\n
