    The Minelab Excalibur Knobs & Caps (Set of 5) are original equipment manufacturer replacement parts for the Minelab Excalibur II series metal detectors. Excalibur II owners working saltwater beaches or freshwater dive sites eventually wear control knobs through repeated adjustments in wet environments, and this 5-piece set restores full tactile control with the same factory components Minelab installs during production. Each set includes five knobs and five yellow caps that match the detector's waterproof housing specifications.

    What's Included with the Minelab Excalibur Knobs & Caps Set

    • Five Minelab Excalibur control knobs (original equipment specification)
    • Five yellow caps (factory color-matched for visibility)

    Why Excalibur II Owners Replace Knobs and Caps

    • Original Minelab parts maintain the detector's waterproof integrity when installed correctly, avoiding aftermarket components that may compromise seal performance in underwater hunts.
    • Factory yellow caps restore high-contrast visibility against dark sand or murky water, making threshold and sensitivity adjustments faster during tide-window hunts.
    • Worn knobs lose tactile feedback in cold water or through neoprene gloves; fresh knobs return crisp adjustment feel for discrimination and volume controls.
    • Five-piece quantity provides knobs for the Minelab Excalibur II 1000 – Professional Underwater Metal Detector control panel, letting operators refresh controls in one maintenance session.

    Direct OEM Fit for Excalibur II Waterproof Housing

    These knobs and caps are the same components Minelab installs on Excalibur II detectors during manufacturing. The knobs thread onto the detector's control shafts, and the yellow caps fit over the knobs. Excalibur II operators hunting surf zones or performing underwater recoveries rely on this OEM fit to preserve the housing's waterproof rating after control replacement. The yellow cap color matches Minelab's original specification, maintaining the detector's visual identification in low-light conditions or when multiple detectors are staged on a boat deck.

    Installing replacement knobs requires removing the old components and threading the new knobs onto the control shafts until snug. The yellow caps press onto the knobs after installation. Operators working in saltwater environments benefit from rinsing the knobs and caps with fresh water after each hunt to prevent salt crystal buildup in the threads.

    Do these knobs maintain the Excalibur II's waterproof rating?

    These knobs maintain the Excalibur II's waterproof rating when installed correctly because they are original Minelab components built to the same specifications as the factory-installed knobs. Operators must ensure the knobs are threaded fully onto the shafts and the caps are pressed firmly into place to preserve the housing's waterproof performance.

    Can I replace individual knobs or do I need the full set?

    You can replace individual knobs if only one or two controls show wear, but this 5-piece set provides comprehensive coverage for your Excalibur II maintenance needs. Operators who replace multiple knobs at once ensure consistent tactile feedback across controls and avoid mismatched xxxx conditions where some controls feel crisp while others remain worn. The set provides spares for future replacements, so you have original Minelab parts on hand when wear occurs. If you only need one or two knobs immediately, you can install those and keep the remaining knobs as spares for later use.

    Answered by Richard T. · July 2026

    What tools do I need to install the replacement knobs?

    Installing replacement knobs on the Excalibur II typically requires no specialized tools, as these are direct replacement parts designed to fit the detector's control shafts. The knobs and caps are original Minelab components that match the factory specifications. When performing maintenance on your detector, handle all components carefully to avoid damage. If you have questions about installation procedures for your specific detector configuration, consult your Excalibur II manual or contact our team for guidance on proper replacement techniques.

    Answered by John W. · July 2026

    How should I clean the knobs after saltwater hunts?

    Clean the knobs after saltwater hunts by rinsing your detector with fresh water to remove salt residue that can accumulate on components. Let the detector air-dry completely before storage to prevent moisture from remaining on the parts. Regular rinsing after saltwater use helps maintain your detector's components and extends their service life. Operators hunting saltwater frequently should make post-hunt rinsing a standard practice to keep their equipment in good condition. Proper maintenance of all detector components, including knobs and caps, contributes to long-term reliability.

    Answered by Dan P. · July 2026

    Are the yellow caps necessary or can I use the knobs without them?

    The yellow caps are necessary components that work together with the knobs as part of the Excalibur II's control system. This set includes both knobs and caps as original Minelab parts designed to function together. The yellow caps also provide high-contrast visibility against dark sand or murky water, making control identification faster during tide-window hunts. Install the caps over the knobs after threading the knobs onto the control shafts to maintain the complete control assembly as designed by Minelab.

    Answered by Richard T. · July 2026

    Will these knobs fit the original Excalibur 800 or 1000 models?
