This demonstration video discusses and shows the features of the Mares Quattro Excel Plus Adjustable Strap Scuba Fins. The Quattro Excel Plus fins feature Channel Thrust Technology, a Whale Tale redesigned foot pocket, and ABS Plus buckles. Channel Thrust Technology maximizes the channeling of water and moves a much greater amount of water compared to the other fins of the same size. The result is greater thrusting power with the same amount of effort. The redesigned Foot Pocket (Whale Tale) is unlike traditional styles that separate materials at the foot pocket resulting in a break in power transmission, a continuum of materials from the blade ensures seamless transmission of power through the entire kick cycle.
