Two fins or one, what’s better?
We always use two fins in the course. That’s because it’s more convenient and two fins are more intuitive for diving. Some training is required before diving with a mono fin—unless you can tap into your inner dolphin.
You’re simply more mobile in the water with two fins. Two fins (also called bi- or stereo-fins) is great when it comes to agility: during course, the training, as a safety diver for your diving buddy, covering long distances and underwater shoots.
One fin (also called a mono fin) is great when it comes to efficiency in a certain time. For instance you are doing an extreme deep dive or want to dive a very long distance underwater. The diving movement is similar to the way a dolphin moves and it streamlines your dive. But using a mono fin takes practice and you loose maneuverability because both feet constrained. That being said, if you can handle the drawbacks, a monofin can also be great fun for a true freediving experience and discovering the flora and fauna. The elegant motion and effortless glide offers a unique experience in the water. In the end, it’s not what’s better, it’s about what kind of experience you after.
