Why do divers hate split fins?
Rumor 1: Lack of Power One of the most prevalent rumors surrounding split fins is that they lack the power needed for strong currents and challenging dive conditions. Critics argue that the split design hampers a diver’s ability to exert force, potentially leading to dangerous situations. The split down the middle of the fin web creates less water resistance while still providing sufficient propulsion. This means that you’ll still get some great speed through the water while requiring less effort on your part. Many new divers, and those with frequent knee pain, tend to prefer the splitfin.
Why do sharks not eat scuba divers?
Often, attacks occur due to mistaken identity—sharks confuse people for their usual prey, such as seals or fish. Scuba divers, with all their gear, bubbles, and slow movements, don’t resemble typical shark prey and are not an attractive target. Most sharks are harmless Species like the White-tipped Reef Shark, Leopard Shark, the humble Wobbegong and even the fearsome looking Grey Nurse Shark do not usually attack humans unless provoked. And then, of course, there’s the world’s largest fish – the Whale Shark – that feeds exclusively on tiny plankton.
Why don’t scuba divers use freediving fins?
The fin will also cause strain on the divers ankles and legs. On the flip side, a big guy with soft stiffness fins can easily overpower them and not get the lift he expects. Not having enough lift while trying to get back to the surface can be a dangerous situation. Most swim coaches prefer short fins to long fins because of the similarity in kick pattern to your natural finless swim. With its quick nature, You are essentially getting double the benefits with a short fin than you would with a longer blade.Short blade fins are generally shorter in length, about 12-16 inches. Unlike the long ones, these training fins are typically used for technique and speed. Short fins provide less propulsion with a smaller surface area than long ones, allowing you to maintain a faster kick.A lighter fin should be avoided by people who have ‘floaty feet’ as the weight of the fin will not be enough to counteract the buoyancy of their feet, causing them to dive with their heads deeper than their feet. Lighter fins are also beneficial for travel, as it is easier to fit within a weight limit.More toe in feels looser but adds drag. Less toe in is faster with less drag but is harder to initiate a turn. Advice for beginner surfers: if you are between sizes – a larger fin will give you more stability to start with. A smaller fin will turn more easily.The more the fin is designed to mimic the feel of swimming without fins, the more benefit the swimmer will get. Long blade fins are best for young swimmers who are still learning how to move in the water, snorkelers, and recreational swimmers. Longer fins improve ankle flexibility and leg endurance.
