The XP Deus X35 9-inch coil is the smallest wireless DD coil in the X35 family, running 35 working frequencies across five base bands. DEUS and ORX owners hunting trashy parks, dense iron sites, and tight-access historical areas get sharper target separation and faster recovery speed from the compact footprint. The coil is waterproof to 6 meters and includes a Boost mode on the low-frequency band that pushes transmission power for deeper detection on high-conductivity targets like large silver coins and cache finds. Wireless electronics eliminate cable snag, and the coil pairs with DEUS version 5 firmware for full frequency control.

Why DEUS and ORX Owners Reach for the X35 9-Inch Coil
- Compact footprint delivers tighter target separation in iron-contaminated sites where overlapping ferrous signals mask coins and small relics, letting you work dense trash layers other coils skip.
- Five base frequencies cover the practical span of relic and coin detecting, with seven offsets per band to shift away from EMI or noisy ground without leaving your preferred frequency range.
- Wireless coil electronics eliminate cable snag and reduce swing fatigue during long hunts, and the submersion rating clears wading and surf conditions on saltwater beaches.
- Boost mode on low frequencies increases transmission power for deeper detection on high-conductivity targets when soil conditions allow, extending effective depth on silver and large copper finds.
- Lighter swing weight and reduced disc radius handle tight-access areas better than the 11-inch or 13x11 X35 coil options.
Sharper Response in Iron-Contaminated Historical Sites
Trashy Park Hunts with Overlapping Targets
The 9-inch footprint reduces the number of targets under the coil at once, letting you isolate coins masked by bottle caps, pull tabs, and ferrous fragments. Run mid-band or high-band frequencies for faster recovery speed on shallow targets, and use the seven frequency offsets to shift away from power line interference without changing your discrimination settings. The wireless design keeps the coil light and maneuverable during grid work, and the waterproof housing handles morning dew and wet grass without concern.

Dense Iron Sites at Historical Foundations
Cellar holes and old homestead foundations bury coins and buttons alongside nails, stove fragments, and wire. The smaller disc area lets you swing between iron clusters and catch non-ferrous targets other coils read as a single ferrous mass. Low-frequency Boost mode pushes depth on large copper and silver when you clear the iron layer, and the DD configuration maintains ground balance in mineralized soil. Our team runs the X35 9-inch on colonial sites where target density makes the larger wireless coils impractical.
