Coach Ferber with College of Charleston commit - Using audible feedback to understand where bat speed happens

@CoachFerber trains with College of Charleston commit @jacksboyd (aka Oil Can Boyd) at Ariel Polanco's @working_with_Polanco training center.  They use the ProVelocity Bat's audible feedback to understand where in Boyd's swing maximum bat speed is developed  @jacksboyd hits reaches his maximum swing speed but rather than reduce resistance, he steps up his game and hits some missiles by "taking it to the next level."
