In an effort to provide a thread where split fins can be bashed while still staying on-topic I have started this thread. Split Fins: Loved by those who use them and despised by those who dont. Claimed to be faster and easier to use by those who actually use them and wont work in current by those who dont. Voted the divers choice in several Scuba Magazine tests by those charged with testing them and those same tests are discredited by those who dont use them. Can only perform well in one style of kicking as told by those who dont use them. You are prevented from hovering or diving upside down when using splits. They are not DIR compliant and no self respecting cave diver would be caught dead wearing them. One of my favorite quotes: They allow people who don't have proper kicking technique to move by moving their feet, but without kicking. With cause a silt out and makes a diver to rototill the bottom, where paddles prevent siltouts and prevent divers from doing any bottom gardening. Will inevitably generate comparisons to propellers, marine life, birds and paddle wheeled boats. We generate posts where engineering pedigrees are trotted out. The US Navy does not use them so they must be un-American. Will sgnerate personal bashing and squabbles in any thread that mentions them. Split fins still out sell all other fins types. Did I miss anything?
