Control Arm with Multi Purpose Knuckle:
The Control Arm is made from extremely tough but lightweight materials to reduce strain when detecting.
It features a swivel design so that it is easy to use and to maintain maximum sweep with each swing of the coil.
When storing the Control Arm folds flat against the shaft. The Multi Purpose Knuckle (on the control arm) provides a pivot point for the Control Arm.
It stops the cable from rotating on the lower shaft, minimises cable noise and gives a fixed point for winding the cable on top of the shaft.
