XP ORX Metal Detector + FX-02 and 9.5" Elliptical DD High Frequency Waterproof Coil (Open Box)

The XP ORX with 9.5-inch elliptical HF coil runs 21 selectable frequencies from 13 kHz to 81 kHz. High frequencies deliver extreme sensitivity to small targets and gold nuggets in mineralized soil. You select frequency through the detector's menu, and the ORX stores your choice in each of the six program slots (four factory, two user-customizable). The frequency range lets you match coil performance to target type and ground conditions, with higher frequencies offering better sensitivity to small gold while lower frequencies provide stable operation in mild ground.

The XP ORX's 9.5-inch elliptical coil and lower shaft are fully waterproof and submersible, so you can hunt the surf line, wade creeks, and work wet sand without damage. The coil's waterproof rating lets you rinse it after saltwater hunts to prevent corrosion on the coil connector and cable boot. Beach hunters run the ORX's salt mode (ground rejection 00-25) to stabilize threshold in conductive wet sand and eliminate the false signals that plague standard VLF detectors in saltwater environments.

The XP ORX runs approximately 20 hours on a full charge of its lithium rechargeable batteries. Both the coil and the remote control have internal lithium cells that charge via USB cable; you can use any certified USB wall adapter or plug into a computer USB port. Battery life varies with settings. The detector provides battery status monitoring so you get advance warning before power runs out mid-hunt.

The XP ORX's Gold program is optimized for low to average mineralization with good sensitivity to medium and large gold nuggets, while the Fine Gold program handles heavy mineralization with sensitivity tuned for small and medium-sized gold. Gold program uses moderate reactivity and threshold settings that work in decomposed granite, dry washes, and alluvial benches where hot rocks aren't dense. Fine Gold program increases reactivity and tightens ground tracking for ironstone country, black sand, and laterite soils where the ground signal would overwhelm a less aggressive ground balance system. Both programs offer five levels of IAR discrimination to filter ferrous trash, and you can manually adjust ground balance from 60 to 90 or use automatic fast-grab tracking when soil phase shifts between swings.

The XP ORX is compatible with the X35 coil range (22cm, 28cm, and 34/28cm coils) in addition to the high-frequency coils it ships with. X35 coils run 35 frequencies from 3.7 kHz to 27.7 kHz, covering lower frequency bands than the HF coils for deeper penetration on high-conductivity targets like silver coins and large relics. Coil swaps require no tools; the S-telescopic Lite stem uses a quick-release cam lock that lets you change coils in seconds. Each coil communicates wirelessly with the remote, so there are no cables to manage when switching between coils for different hunt scenarios. Hunters who cross-shop the XP ORX metal detector with high frequency coil options often buy a second coil (either an X35 for coin depth or a round HF for tight-space work) to cover the full range of targets and terrain types they encounter.

The XP ORX's 9.5-inch elliptical coil (9.5 inches long by 5 inches wide) slips between rocks, brush, and fence posts where a circular coil would hang up, while maintaining similar weight and maneuverability. The elliptical shape allows efficient coverage of large areas without sacrificing target separation. The trade-off is slightly less pinpoint precision: a round coil gives you a tighter signal peak when centering over a target, while the elliptical coil's elongated field requires more careful pinpointing technique. Prospectors working open desert washes prefer the elliptical for ground coverage, while relic hunters in tight homestead foundations often choose the round HF coil for its precise target isolation in trashy sites.

The XP ORX's 9.5-inch elliptical coil and lower shaft are fully waterproof and submersible, with no specified depth limit in the manufacturer documentation. The remote control is splash-resistant but not submersible, so you'll mount it on your hip or chest above the waterline when hunting the surf zone or wading creeks. For full underwater detecting where you need to submerge the entire detector, XP offers an optional antenna accessory that extends the wireless signal range so the coil can operate underwater while the remote stays dry above the surface. In practice, most beach hunters work the wash zone and shallow water without needing the antenna, keeping the remote above water and the coil submerged as waves roll in.

The XP ORX provides two user-customizable program slots where you can save your own discrimination thresholds, reactivity levels, frequency selections, and ground balance settings. This lets you dial in a program for a specific site or target type and recall it instantly without re-entering settings each hunt session. The four factory programs (two Gold, two Coin) remain available and can't be overwritten, so you always have the manufacturer presets as a fallback. In practice, hunters save a custom program for their most-hunted site, tweaking discrimination to notch out that site's specific trash profile, then use factory programs when they're scouting new ground where the trash density is unknown.

The 9.5-inch elliptical HF coil slips easily between rocks, brush, and fence posts where standard circular coils hang up. Its narrow 5-inch width provides the tight maneuverability of a small sniper coil, while its 9.5-inch length maintains rapid ground coverage speed. The trade-off is a slightly wider pinpoint footprint than a round coil in wide-open fields.
