The XP Deus 9-inch HF coil is a wireless DD search coil offering 21 selectable frequencies from 13 kHz to 59 kHz across three base bands (14, 28, and 54 kHz with seven offset steps each). Deus and ORX owners hunting mineralized soil, small relics, or fine gold jewelry reach for this coil when stock frequencies miss faint signals or when target masking buries individual responses. Where a standard 11-inch coil sees a blurred composite in iron-dense parks or black-sand beaches, the HF coil's adjustable high-frequency range resolves thin wire artifacts, open earrings, and sub-gram nuggets that low-frequency platforms treat as noise.

Why Deus and ORX Owners Reach for the 9" HF Coil
- Twenty-one frequency options from 13 to 59 kHz let you tune the detector to soil mineralization and target conductivity, giving you the flexibility to chase small gold in one program and thin silver in another without swapping machines.
- Enhanced sensitivity to low-conductivity targets (fine gold chains, intricate fibulae, wire-frame relics) that conventional mid-frequency coils miss or report as iron.
- Wireless operation eliminates cable noise and physical wear, extending field life and simplifying coil swaps between the Deus remote and wireless headphones.
- Waterproof to 20 feet, built for surf hunting, river wading, and rain without a protective bag.
- Manufactured in France at XP's facility and certified LONGTIME (designed for extended service life), backed by a five-year warranty.
Frequency-Tuned Target Separation in Mineralized Ground
High-frequency coils excel where ferrous trash and hot rocks dominate the signal. The 9-inch HF coil's three base frequencies (14, 28, and 54 kHz) each support seven offset steps, giving you 21 discrete operating points to match soil conditions. In red clay or volcanic black sand, the higher bands (50-59 kHz) reduce ground noise and lift faint signals from small targets buried under mineralization. The mid-range (26-31 kHz) balances depth and separation in iron-littered colonial sites, while the lower HF band (13-15.7 kHz) bridges the gap to standard Deus frequencies when you need a bit more depth on mid-conductors. We've used the 54 kHz setting in Nevada dry washes to pick sub-gram gold nuggets from hot basalt, and the 28 kHz band in trashy East Coast parks to isolate thin silver dimes masked by iron nails.
Small Gold and Wire Artifacts in Prospecting Fields
Gold prospectors working tailings piles, dry washes, and test holes pair the DEUS 9" HF coil with the Deus or ORX for its sensitivity to sub-gram nuggets and fine picker gold. The 50-59 kHz band produces a sharp, high-pitched response on targets as small as 0.1 grams, and the coil's open DD geometry reduces false signals from ground mineralization that plague PI detectors in mild soils. Run the coil in manual sensitivity with minimal discrimination to hear every faint whisper, then use the frequency offset steps to quiet hot rocks without losing target response. For more guidance on coil selection and setup, see our metal detecting tips and FAQs.
Thin Relics and Jewelry in Iron-Dense Parks
Relic hunters working colonial homesites and Civil War camps use the HF coil to separate thin brass buttons, wire-frame buckles, and corroded coppers from square nails and barbed wire. The higher frequencies produce a faster recovery speed, letting you sweep through dense iron without the coil masking good targets under adjacent ferrous signals. The 28 kHz base frequency is a practical starting point for mixed-target sites, offering enough depth for shallow relics while maintaining clear separation on closely spaced finds. Detectorists chasing wireless coils appreciate the HF coil's cable-free operation, which eliminates the physical snag points that slow grid work in brush.
