Question: How can I fix my Minelab Excalibur II? The knob appears to be stripped.
Answer: Anderson Detector Shafts makes a replacement knob set, these deluxe knobs are larger and easier to adjust. Made with a brass insert that will lock down tight with a set screw on the side. The built-in pointer makes it easier to set than stock knobs. Set of 5, available in Blue, Yellow or Olive Green.
