Simple! With PlaneSWING you will receive a link to a comprehensive instructional video and the PlaneGUIDE (an elasticated bungee cord) which stretches across the PlaneSWING from one side to the other. Assuming the correct grip and posture, when the hoop is adjusted to the correct angle, using the calibrated telescopic strut, the PlaneGUIDE should be slightly bowed across the sternum marginally below the midway point of the sternum (across the top of the arm pits). Start with the PlaneGUIDE at approx. 6in (15cm) above the halfway point of the hoop and slide up or down to find the correct setting. NOTE: With the longer PowerSLIDER (simulating a long club 5iron – driver) the PlaneSWING will be set flatter. Conversely using a short PowerSLIDER will require the PlaneSWING to be set at a more upright angle. Also, see “How to Use PlaneSWING”. We are available 24/7 via email and phone to help you get the very best out of your PlaneSWING
