Choose replacement metal detector headphones with the exact connector your detector uses, an impedance near 16 to 32 ohms for passive wired sets, and enough cable slack to move without tugging the plug. That answer changes when the detector uses a proprietary waterproof lock, built-in wireless, or a manual that names a specific accessory path.
May 9, 2026Choose a replacement shaft that matches the detector’s rod diameter within 1 mm, the coil-ear spacing exactly, and the arm-cuff mount before you look at material or finish. If the detector uses a proprietary lower rod, an integrated control-box bracket, or internal cable routing, the model revision matters more than overall length.
May 9, 2026Choose the replacement part only when the model number, connector pin count, and mounting dimensions line up exactly, with only non-electrical sleeves and cuffs allowing about 1 mm of fit tolerance. If the part carries power, seals moisture, or communicates with the detector’s electronics, exact match rules the decision.
May 8, 2026Match the detector’s exact nominal voltage, 12V to 12V or 9V to 9V, keep the same connector and polarity, and fit the battery bay without forcing the door. A higher mAh label does not fix a voltage mismatch.
May 8, 2026Match the connector, mount, operating frequency, and coil diameter first, with 5 to 6 inches for dense trash, 8 to 11 inches for general use, and 13 inches or larger for open ground. A coil that misses the pin count or frequency spec stays unusable even when the shape looks right.
