Fins & Springs
To be a great GUE or DIR Diver, you will need to perfect you fin strokes. To effectively master the various movements you'll need a stiff shorter bladed fin like the Scubapro Jet Fin or the Turtle Fin from XS Scuba. These Diving Fins will help with your back-kick as the stiffer blade doesn't bend as easily as you push your fin back through the water allowing you to load your kick before delivering the power stroke that takes you backwards. The other kicks you'll need to master are the helicopter turn, the frog kick and the proper flutter kick as well as their modified versions, all of this can be learnt effectively during the GUE Fundamentals course.
