USE: Power Fins uses the power of wind resistance to strengthen and develop a powerful swing through the impact zone and follow through.
Wind resistance builds in proportion to the velocity of your swing demanding continued development
Proportional wind resistance will develop swing power according to player's natural swing unlike weighted devices which may disrupt the mechanics of the player's swing
Power Fins assembles quickly and securely to any bat of barrel diameter 2-1/4" or larger. Detailed Instructions Included.
Once assembled, just insert handle of bat through Power Fins and swing away
If you can (properly) swing a bat of barrel 2-1/4" or larger, you can use Power Fins - all ages and abilities welcome!
