XP Deus 9″ Round Waterproof DD High Frequency Search Coil (Deus & ORX) – D01HF

The XP Deus 9-inch HF coil is compatible with the XP Deus and XP ORX metal detectors. It is not compatible with the Deus II, which uses a different coil connector and communication protocol. The HF coil pairs wirelessly with the Deus remote control or the WS4 / WS5 wireless headphones, and you can run the coil directly with the headphones in standalone mode if you prefer a lighter setup. Verify your detector model before ordering, as the mounting hardware and firmware differ between the original Deus platform and the Deus II.

The HF coil operates on 21 selectable frequencies organized into three base bands: 13 to 15.7 kHz, 26 to 31 kHz, and 50 to 59 kHz. Each base frequency (14, 28, and 54 kHz) supports seven offset steps, giving you fine-tuning control to match soil mineralization and target conductivity. Higher frequencies (50-59 kHz) excel on small gold and low-conductivity targets, mid-range frequencies (26-31 kHz) balance depth and separation in trashy sites, and the lower HF band (13-15.7 kHz) bridges the gap to standard Deus frequencies when you need a bit more reach on mid-conductors.

The XP Deus HF coil is waterproof to 20 feet (6 meters), built for surf hunting, shallow river wading, and rain without a protective cover. The coil housing and wireless electronics are sealed to the same standard as other XP Deus coils, so you can submerge the coil and lower shaft during beach hunts or creek searches. The Deus remote control and most wireless headphones are splash-resistant but not fully submersible, so only the coil and lower shaft go underwater. Rinse the coil with fresh water after saltwater use to prevent corrosion on the mounting hardware.

The HF coil battery provides approximately 20 hours of runtime on a full charge. Actual runtime varies with transmit power and frequency, as higher frequencies and maximum power settings draw more current. The coil charges via XP's standard charging clip, which connects to the coil's charge port on the lower shaft. The coil shares the same charging accessories as other Deus components (remote, headphones, pinpointer). Carry a spare charging clip and a USB car adapter for multi-day trips to ensure uninterrupted detecting sessions in the field.

The HF coil's advantage is its extended frequency range (up to 59 kHz) and enhanced sensitivity to small, low-conductivity targets that standard Deus coils miss or report as iron. Gold prospectors use the HF coil to detect sub-gram nuggets in mineralized ground, and relic hunters use it to resolve thin wire artifacts, open rings, and corroded coppers in iron-dense sites. The higher frequencies produce sharper responses on fine gold, thin relics, and intricate jewelry that conventional lower-frequency coils struggle to detect.

The HF coil works with the Deus WS4 and WS5 wireless headphones, and you can run the coil in standalone mode with the headphones as the primary control interface. This setup eliminates the remote control and creates a lighter, cable-free configuration for fast-paced hunts. The headphones display frequency, sensitivity, discrimination, and other settings, and you adjust parameters using the headphone buttons. Pairing the coil to the headphones follows the same wireless protocol as pairing to the remote, and the coil remembers the last paired device. Check out open-build coils for more wireless options.

The HF coil works well for beach hunting, especially in dry sand and wet sand where small gold jewelry and thin chains produce faint signals. The coil's waterproof rating (20 feet) supports surf hunting and shallow wading, and the higher frequencies (28-59 kHz) reduce ground noise from black sand mineralization. In saltwater, use a lower transmit power and run the coil in tracking or manual ground balance to minimize false signals from wet sand. The 9-inch size is more maneuverable than larger coils in tight spaces around jetties and pier pilings, and the wireless design eliminates cable wear from sand and saltwater.

The HF coil package includes the 9-inch round DD search coil, a coil cover, the lower shaft, and a hardware kit (mounting bolts, washers, and the coil connector). The coil cover is a molded plastic skid plate that protects the coil housing from rocks and abrasion, and the lower shaft is the carbon-fiber tube that connects the coil to the Deus middle shaft. The hardware kit contains the fasteners needed to mount the coil to the shaft and secure the cable routing. You supply the Deus or ORX detector, the middle and upper shafts, the remote control or wireless headphones, and the charging accessories.

The XP Deus HF coil is manufactured in France at XP Metal Detectors' facility. XP designs, engineers, and assembles all Deus components in-house, and the HF coil carries the company's LONGTIME certification, which indicates the product is designed for extended service life with replaceable wear parts. The five-year warranty covers manufacturing defects and component failures under normal use, and XP's French service center handles repairs and firmware updates for detectors sold worldwide. French manufacturing ensures consistent quality control and faster turnaround on warranty claims for European and North American customers.
