Salt behaves as a highly conductive target at certain frequencies, generating false signals that slow down an entire hunt. BBS eliminates that problem by broadcasting across 17 frequencies simultaneously, holding target audio stable regardless of salt concentration. Moving from the dry sand line to the foam and back requires no mode switching; auto ground balance compensates continuously. A sand scoop rated for surf retrieval rounds out the kit.

Coins, rings, and relics settle in lake beds and river bends where on-land competition is nearly zero.

Rather than selecting a single operating frequency, which fixes the depth-versus-target-size tradeoff for that entire hunt, BBS transmits all 17 frequencies simultaneously from 1.5 kHz to 25.5 kHz. Low frequencies penetrate deeper and respond better to large conductive targets. High frequencies respond better to small, low-conductivity targets like fine gold. Running all 17 at once means the Minelab Excalibur II captures response data across a full conductivity spectrum without any user frequency selection.\u003c\/p\u003e\n\n\u003cp\u003eAuto ground balance works alongside BBS to suppress ground mineralization interference in real time. On saltwater beaches, where VLF machines fight a constant battle against salt-induced false signals, the Minelab Excalibur II's multi-frequency approach effectively separates salt response from actual target signal. A gold ring buried 10 inches in wet sand at the surf line returns a reliable, repeatable audio response rather than the choppy, unstable signal a single-frequency machine produces in those same conditions.\u003c\/p\u003e\n\n\u003ch2\u003eBuild, Controls, and Audio\u003c\/h2\u003e\n\n\u003cp\u003eThe Excalibur II's control body mounts shaft-side, a slimline pressure-resistant housing that keeps the center of gravity low for balanced underwater work. Five rotary dials control Threshold, Sensitivity, Volume, Discrimination, and Mode, all accessible with neoprene dive gloves. There is no display; target information comes entirely through audio tones rather than numeric target ID readings. Removing the screen eliminates a pressure-failure point and keeps the operator's focus on coil position rather than a readout.\u003c\/p\u003e\n\n\u003cp\u003eIncluded Koss 8-ohm hard-wired waterproof headphones deliver multi-tone continuous audio discrimination. At lower discrimination settings, ferrous targets are rejected and non-ferrous targets pass. Increasing discrimination progressively removes conductive targets, letting you tune out aluminum while keeping gold and silver tones. The headphones use the same hard-wired, no-external-connector approach as the coil, with no plug to leak under pressure. The Excalibur II has no wireless audio option. High-visibility fluorescent yellow bodywork makes the detector identifiable in murky water or low ambient light, a practical safety feature for diving and night beach operations. Weight is 2.3 kg (5.1 lbs).\u003c\/p\u003e\n\n\u003ch2\u003eThe 10\" Double-D Coil\u003c\/h2\u003e\n\n\u003cp\u003eThe 10\" Double-D Smart coil is hard-wired to the Minelab Excalibur II, making the coil and control body a unified, sealed assembly. This eliminates the coil-to-shaft connector that, on other machines, is a potential leak point under sustained pressure. The DD configuration provides a narrower detection field than concentric coils, improving target separation in wreck debris fields and beach junk zones. The slimline profile reduces water resistance during lateral coil sweeps underwater.\u003c\/p\u003e\n\n\u003cp\u003eThe coil is not interchangeable. The 10\" DD is the coil the Excalibur II ships with and the coil it operates on. No aftermarket coil options are available for this machine.\u003c\/p\u003e\n\n\u003cfigure\u003e\n  \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0760\/1464\/9628\/files\/Excalibur_II_Lifestyle_underwater.png?v=1763149575\" alt=\"Minelab Excalibur II metal detector in use underwater, showing the detector being swept near a sandy seabed\"\u003e\n\u003c\/figure\u003e\n\n\u003ch2\u003eMinelab Excalibur II Specifications\u003c\/h2\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTechnology:\u003c\/strong\u003e BBS (Broad Band Spectrum), RCB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Frequencies:\u003c\/strong\u003e 17 simultaneous (1.5 kHz to 25.5 kHz)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSearch Modes:\u003c\/strong\u003e Discriminate, All Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePinpoint:\u003c\/strong\u003e Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiscrimination:\u003c\/strong\u003e Variable (continuous audio-based; no target ID segments or numeric readout)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTarget ID:\u003c\/strong\u003e None\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDepth Indicator:\u003c\/strong\u003e None\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGround Balance:\u003c\/strong\u003e Automatic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSensitivity:\u003c\/strong\u003e Auto and manual (1–10)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoil:\u003c\/strong\u003e 10\" Double-D Smart coil (hard-wired, non-interchangeable)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard Shaft Length:\u003c\/strong\u003e 114 cm to 122 cm (45 in to 48 in)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDive Shaft Length:\u003c\/strong\u003e 82 cm to 91 cm (32 in to 36 in)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 2.3 kg (5.1 lbs)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBattery:\u003c\/strong\u003e 12V \/ 1000 mAh NiMH rechargeable (included)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBattery Life:\u003c\/strong\u003e 14–19 hours\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWaterproof Rating:\u003c\/strong\u003e IP68 to 60 m (200 ft)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAudio:\u003c\/strong\u003e Multi-tone continuous (hard-wired Koss waterproof headphones included)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWireless Audio:\u003c\/strong\u003e No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisplay:\u003c\/strong\u003e None\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 12 months (control box and coil)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhy Buy the Minelab Excalibur II from Serious Detecting\u003c\/h2\u003e\n\n\u003cp\u003eWe are an \u003ca href=\"\/pages\/customer-care__about-us\"\u003eauthorized Minelab dealer\u003c\/a\u003e, which means every Excalibur II we ship carries the full 12-month manufacturer warranty on the control box and coil, covered directly by Minelab.
