SEAC Motus Carbon Fins



The SEAC Motus Carbon has an interchangeable carbon blade fin with a closed foot pocket. The foot pocket material is made in two materials with different densities. Hard thermoplastic rubber for the sole and ribs, and soft around the foot to optimize the comfort/performance ratio. The fins blade material is unidirectional 100% pre-preg carbon and internal reinforcements in carbon with 45° weave.



The Seac Motus Carbon long fins are loved by freedivers from their first experience thanks to the outstanding comfort of the foot pocket and the ease of finning. The 22° angle between the blade and foot pocket optimizes thrust with minimum effort. The Seac Motus Carbon freediving and spearfishing fins are easy to put on thanks to the full foot pocket that is made in a double thermoplastic material: a harder rubber for the sole and a softer one for the back of the foot. For an optimal fit we recommend using 2-3mm thick neoprene socks (such as the Seac Standard 2.5mm and Seac Anatomic Camo 3.5mm) with the Seac Motus fins of the same size as the shoes you use daily.

The Seac Motus Carbon long fin blade offers excellent reactivity with lots of propulsive force. The blade is made of unidirectional 100% pre-preg carbon and internal reinforcements in carbon with 45° weave. The blades are interchangeable and also available in thermoplastic material black and 5 camouflage colours perfect for every underwater freediving and spearfishing need: grey, green, brown, red and blue.

The feeling of great comfort makes it possible to use the Seac Motus long fins all day, making them ideal for diving and during intensive fin training for dynamic apnea. The Seac Motus Carbon interchangeable blade fins are available in US sizes 4.5/5.5, 6.5/7, 8/8.5, 9.5/10, 11/12, 12.5/13.5 for all women and men who love underwater fishing, free diving and diving recreationally.
