HOG Tech 2 Fin provides better finning control while still retaining the power that the Hog Classic tech Fin offered. We could go on for hours about the fin and how it magically makes you fly underwater, except of course it doesn't. You need to bring the buoyancy, finning technique and leg power to the table, when you do that this fin will meet your needs and translate your ability to actual diving much better than many fins on the market. This fin is negatively buoyant in the water. النوع الغوص الحر والغطس
