The Updated DB-70 Automatic Wheel Balancer from Dannmar offers digital sensor technology for reliable, consistent performance as well as seven balancing modes and the ability to handle wheels up to 28" in diameter. The DB-70 has a touch-pad panel that displays tire and wheel assembly graphics designed to simplify the process of entering wheel data. With the wheel on the balancer, the DB-70 automatically calculates the precise amount and location of weight needed for optimal balance in just seven seconds, says the company. For larger wheels, the DB-70 comes with a truck cone/space ring adapter set.
