Effective and efficient are the words that best describe our electric pokers. They're light and easy to handle, yet provide the vibration needed to remove air voids in the concrete. Fast startup, a wide radius of action and rapid acceleration for removal of air voids add to the effectiveness. Plus, the electric motor is highly efficient and the low voltage helps protect the operator.
