The material and design of hand paddles should be selected according to their intended use. Common materials like silicone or TPR offer both flexibility and durability. Long carbon fiber fins are suitable for freediving propulsion, while shorter, split-fin designs enhance maneuverability. The fit of the foot pocket and the stiffness of the fin blade directly affect efficiency and comfort.
Many swimmers have stated that hand paddles can effectively increase their sculling speed and enhance their feel for the water, which helps improve their technique.
The downside of hand paddles is that excessive use can lead to shoulder muscle fatigue and strain, so they need to be used reasonably.
