The softer the blade, the longer it takes to accelerate, but the more effortlessly you can maintain speed.

Our COMPETITOR fins come with our softest blades to allow elite athletes to return from 80m+ dives with minimal oxygen consumption.

Our INSTRUCTOR fins come with our hardest blades to allow instant acceleration to top speed when following students.

Our FORAGER fins strike a happy balance, providing plenty of power against currents and fish without tiring the legs. If you are freediving recreationally, rather than teaching or competing, the FORAGERS are usually your best choice.

The longer the blade, the more effortlessly you can move in a straight line for long distances, as the blades begin to "resonate" at their natural driving frequency.

Our COMPETITOR fins come with our longest blade length of 1000mm, allowing elite athletes to maintain a steady pace on the way back from 80m+ dives with minimal buildup of lactic acid.

Our INSTRUCTOR fins come with our shortest blade length of 560mm, allowing for easy maneuvering behind students.

At 820mm, our FORAGER blades are in the middle, allowing deft maneuvering through reefs and kelp while also supporting longer blue-water ascents.

The wider the angle, the softer the feel of the blade. Wider angles also allow less tension during freefall, because you don't have to flex your calves as firmly to point the blades directly behind you. Our COMPETITOR fins come with our widest blade angle at 29° to allow for effortless freefall, while our INSTRUCTOR and FORAGER fins come with a more acute blade angle of 26° to allow for quicker delivery of power.
