RBI ProSwing

Swing trainer and on deck bat weight.
Designed to assist players with finding their correct swing path while increasing hand speed when swinging the bat.
Helps players develop quick hands, power transfer, bat positioning, swing path and muscle memory.
The device is filled with shot (small pellets) to give instant feedback to hitters.
Place it on the end of the bat barrel.
Once the hand and feet are set in the proper position the shot is moved and located in the base of the chamber.
As the swing begins, the shot is moved through the chamber and at the point of impact the shot whips through the chambers.
Allows the batter to feel the power as well as hear the shot as they reach the impact zone of their swing.
The better you get, the closer you will hear the "SWISH" at the impact point. Batting drills included.
Endorsed by Texas Rangers Hall of Famer Rusty Greer.
Fits all baseball and softball bats.
