The Biondo Digital Mega Dial is a two-piece unit, and both the control head and the display board require 12V or 16V power and ground to operate. The control head is typically placed near the driver, and the display board is mounted to face the tower. This unit is independent and works along side any delay box, throttle stop, or ignition. With the Mega Dial, you can avoid dial-in errors, and have the option to change your dial-in, right up to the last second. This unit also has the ability to store two times in memory, called ''Time 1'' and ''Time 2'', allowing for large number changes without a lot of time wasted scrolling. This can be beneficial for 1/4 mile and 1/8 mile racers, they can store 2 different dial ins, or a driver who ''super'' class races can store his ''super'' dial in, and his bracket dial in. The Mega Dial can be mounted to window or Lexan with Hook & Loop strips, and will fit inside any dial board bracket that is 7.5'' wide such as the dragster mount (p/n 376-BRP-DB-3) for 3'' Goza-style air pans listed below.
