For the ones which aren’t knowledgeable about the game of free-dive spearfishing, it involves using a breath-hold technique and swimming down to your target thickness at which you would then take a fish with an elastic band-powered spear weapon.
This is a dangerous game for many reasons. With a breath-hold technique is dangerous since you start to push your limits in thickness, you face the risk of losing consciousness due to lack of oxygen to the brain. Another element of risk associated with this game is that the presence of predators such as sharks. When you’re successful in swimming , finding a fish and shooting it with your spear gun, getting blood in the water is inevitable. The blood in the water can’t just attract them but also place them in a feeding frenzy with competitive behaviour. It is not if, it is when.
All risk aside, free dive spearfishing gives you a pure, euphoric adrenaline rush. From the minute you enter the water, you have left your normal surroundings and entered an alien domain where everything is faster, more agile, and more conducive to the environment around them. An extremely caveman-esque adrenaline rush washes over you while you swim down with only you and your spear gun, searching for prey and trusting another predator does not materialize out of the blue.
When descending, sometimes there is what’s called a thermocline. Immediately beneath the thermocline the water gets noticeably colder and visibility is significantly improved. Breaking through the thermocline is obviously an extreme moment, one second you are surrounded with this blurry water and can barely see your hand before your face and the next minute it is like a veil has been lifted and you can see clearly around you.
When one eventually reaches the bottom or their target thickness, selects which fish they need to harvest, makes the kill shot, and propels down themselves the surface, the feeling of success and achievement is incomparable.
