PlaneSWING is effective specifically because you DO NOT HIT BALLS when in use. The effectiveness of PlaneSWING is achieved by regular use of the PowerSLIDER which trains and conditions the golfing muscles. Using a golf club and hitting balls is not only dangerous and invalidates any warranty, it also defeats the object of PlaneSWING, which is to ingrain a powerful and repeatable motion without the distraction of hitting balls. Once you step out of PlaneSWING and hit balls, the results are dramatic and with regular use the positive change could become permanent. What we do suggest is taping up an old club (say a 4 iron – you may need to re-set PlaneSWING to a slightly steeper swing plane angle) and swinging slowly around the PlaneSWING upper hoop. This enables you to replicate the motion you’ve been training and to observe club face position.
