Use the Shell Stick as a way for players to learn how to properly utilize a stiff arm when running to the perimeter. The Shell Stick has a built in shock absorbing mechanism so that the coach or players does not get hammered from repeated contact. Proper placement on the face-mask not only gives a realistic feel but it also teaches players how to avoid penalties when stiff-arming. On defense use the Shell stick to defend against cut-blocks. Placing one hand on the helmet and one hand on the shoulder pads give players a game-time feel on how to attack and defend against a player trying to lunge at their feet. Warranty 2 years.
