There are a number of different fins to choose from, including short and long plastic, scuba, bi-fins, and monofins. Each type of fin has its own strengths and weaknesses. The type you choose should depend on your experience, your location, and your budget.
Bi-fins are two fins, which are easier to use than monofins. This will allow you to keep your hands free, while also making it easier to change directions. They are also easier to store.
Bi-fins are a good choice for recreational freedivers who don’t plan on doing deep dives. Bi-fins allow you to easily switch directions, but they are not as stable as monofins. They are also easy to break.
Short freediving fins are similar to snorkeling fins. They reduce the thrust and drag of the fins when turning, and they allow you to move faster through the water. They are ideal for chasing fish or exploring tight areas. They also make it easier to resurface safely. They are also less cumbersome than long freediving fins.
Long freediving fins are great for longer dives, and are especially useful for divers who have strong leg muscles. Long blades displace more water per kick, which provides more power. This also makes them a good choice for a quick dash to the bottom.
