Product Description: Federation Lip-Jet Fins from Cressi, model FA405103, are a superior choice for cold water diving. These fins are characterized by their 7mm thick blades, which provide excellent insulation and increased buoyancy, making them ideal for diving in temperatures below 77 F (25 C). checked The fins come with finned shafts measuring 115cm in length and are compatible with the Cressi-Sub 843607509770 boots (sold separately).
The blade design of these fins is based on Cressi's proprietary "Easy Motion Technology," which focuses on delivering efficient and natural kicking power. The relatively narrow blades, combined with an elastomeric joint in the finner, allow the fins to flex and adapt to the movement of the diver's lower leg. This results in less energy being required to move through the water, making diving feel more effortless and comfortable.
One of the most notable features of the Cressi FA405103 fins is the inclusion of Cressi's patented "Lip-Jet" system. This technology incorporates two vents on the blade's trailing edge that create channels for water to enter and exit during the kicking cycle. The water is forced out during the power phase of the kick, providing an additional propulsion boost, while the vacuum created during the recovery phase helps to pull the fin back toward the diver's feet. This results in increased efficiency and improved forward thrust.
The durable construction of these fins ensures they can withstand the demands of rigorous diving conditions. The blades are made from a tough, injection-molded rubber material that is resistant to wear and tear, while the fibreglass finners provide added strength and stability. The finner's surface is coated with a layer of antifouling paint to prevent marine growth and maintain optimal performance.
The Cressi FA405103 fins are designed to be used with the Cressi-Sub 843607509770 boots (sold separately). These boots offer excellent fit and comfort, featuring a soft neoprene material that insulates the diver's feet in cold waters. The boots also have an adjustable ankle strap to ensure a secure connection between the fin and the foot.
Overall, the Cressi FA405103 fins are an excellent choice for anyone seeking to dive in cold waters, as they combine efficient and natural kicking power with superior insulation. Their innovative Lip-Jet system helps to maximize propulsion, ensuring a comfortable and enjoyable diving experience. The durable construction ensures they can withstand the demands of frequent use, making them a sound investment for avid divers.
