Product Overview

The Mares Avanti Quattro Open Heel Fin has been the most successful in scuba diving for the last 20 years.  Appropriate for all diving conditions, the Avanti Quattro Plus Open Heel Fin was redesigned for even greater proficiency with more responsive material that allows for greater channel formation.  The result is a more comfortable kick while improving overall performance. The channel formation is created through the blade’s four (Quattro) ribs that cause it to arch while finning.   By improving the channel formation, more water is displaced in the proper direction.  Fin operation is smoother and the enhanced energy transmission (foot-foot pocket interface) is measureable.  The new materials are the result of technological improvements in manufacturing and design.  The stabilizing trim tabs improve stability and eliminate the ankle twisting phenomena. The anatomical foot pocket conveys more power to the blade. Countless computer simulations and field tests were performed until the Quattro+ was perfected.

Included within the improvements of the Avanti Quattro-Plus Open Heel Fins is Mares’ bungee strap system.  The introduction of bungee straps with the Quattro Plus fins provide several benefits.  There is no need for adjustment each time the fin is worn because the bungee provides a perfect fit each time even when different boots are worn.  Dramatically easier to don and doff, the diver no longer needs to release buckles or loosen adjustable straps.  This allows for simple entry and exits whether boat or beach diving.  The bungee straps also compensate for depth compression.  Inevitably, due to water pressure, even neoprene boots will compress.  The bungee straps will remain secure, no matter the depth automatically.  

The Mares Avanti Quattro-Plus Open Heel Fins are available in a wide range of colors.  In addition to black, highly visible colors are offered.  This provides improved identification even while underwater and allows for fun, fashionable color choices.
