Monofin
Definition
A monofin is a single, large fin used in freediving and competitive swimming, where both feet are inserted into foot pockets side by side.
More on Monofin
Unlike traditional fins, a monofin connects both feet in one blade, requiring a dolphin-like undulating motion for propulsion. It's commonly used in freediving for its efficiency and speed. Monofins allow divers to reach great depths with fewer kicks and less oxygen consumption. However, they require advanced technique and aren’t typically used in recreational scuba. Freedivers train extensively to master the body wave motion needed to control and steer the monofin effectively.
Frequently Asked Questions
Monofins provide powerful, streamlined movement with minimal energy loss, ideal for deep dives and dynamic apnea events.
No. Scuba divers need independent leg movement for control, maneuvering, and emergencies. Monofins restrict that.
Core, glutes, and lower back muscles are heavily engaged in the wave-like motion of monofin propulsion.
Improper use can strain the back or legs. It’s essential to train with instructors and use correct form.
Consider blade stiffness, foot pocket size, and your diving style. Softer blades suit beginners; stiffer for depth and performance.
