Effective batting practice is possible without a partner and in a space-saving manner. Batting practice, known as "hane-uchi," is possible with an automatic launching machine, eliminating the need for a partner. While retaining the features of the previous model (FSSM-220), the following have been added: <<Launch Interval Adjustment Function>> and <<New Function for More Stable Launching>>. By changing the launch angle, it is possible to launch the speed shuttle in both a straight trajectory and an arcing trajectory. The design minimizes vibration and noise during launch, allowing for use indoors or during nighttime practice. • Operation confirmed.
