FlexiDive is an free diving innovation created by Travelons founder Robin!It allows the diver to dive deep without wasting energy. It is easy to use and practical in several ways. Check out the end of this video to see it in action:
If the diver didn't bring weights to the dive, he or she can collect rocks from the beach to use as weights. Once down, the diver can continue to dive deeper or explore at the same depth. After the dive, the diver can pull up the weight with little or small effort (depending on the weight). The line gets pulled into the mechanism and can be locked in with a click.
