OMEGA AQUATICS - The Amphibian |
 |

| A natural evolution within the dive industry, the Amphibian™ fin system is designed to be strapped on prior to entering the water and removed after exiting. The heavy-duty springs push the soft blade webbing up to ride gently against the shin while on the surface. This makes walking, climbing boat ladders and other movements as easy as wearing no fins at all. Once in the water, The Amphibian™ blades are flipped down into swimming position by simply kicking naturally in the water, and flipped back up by pushing back on the release levers before getting out. Large sizes now available in dive stores. X-Large will be shipping in Mid December. Medium and Women's sizes will be available in March. Available color blades with black foot pocket - black, yellow, blue. Includes custom strap and buckles. Limited lifetime warranty. Click here for product warranty and usage information.

TUSA FINS - SF-8 X-PERT ZOOM |
|||||||||||||||||||||||||
 |
When using the standard, traditional blade fin, with the leg completely extended, there remains an angle of 27 degrees between the heel and the foot and the calf of the leg, causing a 10% loss of propulsion. Because the fin is angled below the body, during the kick phase, the body is pushed forward, instead of straight ahead. With the SF-8 fin, that 27 degree angle has been designed into the fin so the fin is parallel to the leg. This means that 100% of the energy expended during the kick phase is directed toward the propulsion of the diver. TUSA developed a robot that can replicate the motions of a human being. The robot is able to mimic the human under kick-bending at the ankle, knee and hip in one fluid motion. Using this robotic science, TUSA has been able to analyze the performance of the fins under several conditions. The robot is able to swim, through the water using kick variations, such as a large scissor kick with a slow repetition and vice versa. Using the latest technology, this robot measures the energy expended during the kick and the propulsive force that is created using that energy. | ||||||||||||||||||||||||
