A new fin that literally looks like the back half of a fish was launched this week at DEMA. Called the "mor-Fin," its patent was just filed last Monday (Nov. 6), Morfin Corp. President John Melius told DeeperBlue.net today. While most fins work like paddles, using drag propulsion by "creating a void in the water into which they are pulled," Mor-Fins’ hydrodynamic wing shapes "create lift just like airplane wings," according to a company statement. While divers can propel themselves via the traditional fin kick, mor-Fins come into their own with the use of a smaller kicking stroke. Go to www.mor-fin.com for more information.
