OKM Rover UC
W-9 and vendor pack with every quote
Shipped direct from the manufacturer
A wireless telescopic probe controlled from a paired Android smartwatch, run through four modes: Magnetometer, 3D Ground Scan, Pinpointer and Ground Balance. OKM sells a current smartwatch-controlled edition and keeps a separate page for a superseded one, and three of the five dealer pages we checked still publish the older edition's figures.
01
The Rover UC is one probe controlled from a paired smartwatch, not a separate box you carry
OKM builds the current Rover UC around one telescopic probe, not a separate control box. Folded, it runs about 67 cm (26 in); extended, 670 to 1380 mm. The probe alone weighs 500 g (17.6 oz). The probe itself carries a small LCD minidisplay, 80 by 160 pixels, showing battery status, pedometer and compass. A pre-configured Android smartwatch, running the OKM Rover UC App, is the primary control interface. Its own Activity Screen adds a heart rate readout, and a paired Android smartphone can add the same control functions. Inside the probe, a Cortex-M0+ processor samples the SCMI-15-D sensor at 240 values per second, 15-bit resolution. Detection runs on OKM's own GST (Ground Scan Technology) and EMSR (Electro-Magnetic Signature Reading) methods. OKM's manual describes EMSR as reading metallic objects plus natural ground features: rock formations, cavities, voids, faults, ground water, and other non-metallic objects. OKM states the Rover UC is best suited for detecting sepulchers, treasures, buried utilities and tanks. Bluetooth headphones ship in the box. They do not arrive already paired: per the manual, you pair them manually through the Android device's Settings > Connect > Bluetooth menu, so feedback stays private rather than broadcasting from a speaker, the point of the undercover design.
02
Four modes run in a set order: clear the surface, scan, then pinpoint
The Rover UC runs four operating modes from the same probe. Magnetometer comes first in OKM's own recommended workflow. It is an acoustic and basic graphical measurement of ferromagnetic metal near the surface: iron, cobalt, nickel and alloys. OKM recommends it to clear surface debris before a deeper scan, since fewer small metal items in the soil let 3D Ground Scan resolve further down. 3D Ground Scan is the main data-gathering mode: a graphical measurement of a defined field. It configures for Field Length (Auto or a fixed distance), Impulse Mode (continuous or one impulse per trigger press) and Scan Mode (Parallel or Zigzag lines). Results are studied afterward on a computer, in Visualizer 3D Studio. Pinpointer runs after a scan, for real-time signature analysis of a located structure. OKM's manual describes a positive-negative signature for ferromagnetic metals, and a pure positive signature, with a small secondary peak typical of precious metals, for non-ferromagnetic metals. Non-metallic targets such as voids, tunnels or buried plastic pipe instead show a pure negative signature. Ground Balance is available inside both Magnetometer and Pinpointer, to recalibrate against metallic trash or surface contamination, and can be run as often as needed.
03
OKM's current Rover UC replaced an earlier edition, and every figure here follows the current manual
OKM's current Rover UC product page and its own September 2022 hardware manual agree on the current specs. The probe weighs 500 g (17.6 oz), runs on an internal rechargeable battery rated for about 48 hours on a full charge, and charges via USB-C. An earlier Rover UC hardware edition instead carried a 0.65 kg probe, about 10 hours of operating time, and power from two AA primary batteries. Three of the five dealer pages we checked still publish those older figures. Two publish the current figures, matching OKM's own current page exactly. OKM itself maintains a separate, superseded product page for the older edition. It states plainly that the older edition is no longer manufactured and that the current Rover UC is its successor. We have not independently confirmed with OKM's dealer desk which hardware revision ships against your own order. Every figure in this description follows OKM's current manual. Call +1 888 850 6533, Monday to Friday, 9 to 5 Mountain Time, before you order, and we will confirm the exact hardware revision against your quote.
04
Bluetooth 5.2 links the probe to the smartwatch; the headphones pair separately
The probe talks to the smartwatch over Bluetooth 5.2. Per OKM's current manual, that link covers a maximum range of about 8 m line of sight, at 2.4 to 2.4835 GHz. Maximum transfer rate is 1 Mbps, with a receiving sensitivity of -85 dBm. The older Rover UC edition instead used Bluetooth Class 2, rated at about 10 m, one more figure that separates the two hardware editions covered above. Bluetooth headphones ship in the box, to keep audio feedback discreet rather than broadcasting from a speaker. They do not arrive already paired: the manual gives a six-step procedure, power on the headphones, open the Android device's Settings, go to Connect > Bluetooth and enable it, search, then select the headphones from the list to pair them, a one-time setup step. The manual does not state whether the headphone pairing shares the same Bluetooth 5.2 radio or carries its own version and range figures. Because control runs over the probe-to-smartwatch link, a clean pairing between probe and watch is part of normal setup, not an optional extra.
05
Operating range runs -5 to 60°C, and the unit is not weatherproof
OKM's current manual rates the Rover UC for operation between -5 and 60°C, with storage from -10 to 70°C and air humidity from 5 to 75 percent. OKM's own general FAQ separately claims its whole line of 3D ground scanners operates down to -20°C. That figure is not specific to the Rover UC and is not repeated on this product's own spec sheet, so this description uses the product-specific -5°C figure. The manual states plainly that the unit is not weatherproof, and that water or condensation can destroy it. Watch for condensation when moving the probe from a cold place to a warm one, and let it dry out before switching it back on.
06
OKM's manual gives one warning above all others: treat a buried signal as possible unexploded ordnance
OKM's manual carries a dedicated warning for ground in former conflict areas, where unexploded relics from past wars can remain buried. It instructs operators not to dig or hack at an object after receiving a signal. A red or reddish tint near the surface is an indicator of rust. Curved or round objects, or ones with buttons, rings or pins, count as an alarm. Ammunition should be left exactly where it is found, never taken home: moving a suspect object can itself produce enough friction to trigger it. The instruction is to mark the location and report the find to the police. Separately, the manual notes the unit has a built-in anti-tampering module that destroys it if improperly opened, and that there are no user-serviceable parts inside. Used properly, the device's high-frequency signals do not pose a known health hazard, according to current scientific knowledge.

Safety and cautions (from the manual)
| General notes | Any failure to observe the safety precautions given, or any use for purposes other than the ones the device is designed for, may result in damage or destruction of the processing unit and/or its accessories or connected components |
| Anti-tampering module | The device has a built-in anti-tampering module which will destroy the unit if it is improperly opened. There are no user-serviceable parts inside the unit |
| Possible health hazards | If used properly this device usually does not pose any health hazards; according to current scientific knowledge, the high-frequency signals are not harmful to the human body on account of their low power |
| Surrounding area, condensation | When moving the unit from a cold place to a warmer one, watch for condensation; do not operate until any condensation has evaporated. The unit is not weatherproof and water or condensation can destroy it |
| Surrounding area, magnetic fields | Avoid strong magnetic fields, which may occur near large electric motors or unshielded loudspeakers; try to avoid using the equipment within 50 m (150 ft) of this type of equipment |
| Metallic objects on the operator | Metallic objects on the ground (cans, tin, nails, screws, debris) can influence scan data; it is also good practice to remove metallic objects from your person (cellular telephones, keys, jewelry) and not wear steel toe boots |
| Voltage and charging | The power supply cannot be outside the indicated range of values; use only approved chargers included within the delivery scope |
| Data safety | Data errors can occur if the range of the sender module has been exceeded, the power supply or battery is too low, the unit is operating too close to devices that emit disturbances, or in atmospheric conditions such as electrical storms and lightning |
| Maintenance, avoid list | Avoid penetrating water, strong dirt or dust deposits, hard impacts, strong magnetic fields, and high or long-lasting heat effect. Clean with a clean, dry, soft rag or cloth; ensure all batteries are fully charged before use |
| Danger of explosion during excavation | The manual carries a dedicated warning that ground in many former conflict areas conceals unexploded relics from past wars; it instructs operators not to dig or hack at an object on receiving a signal, to note that a red or reddish ground color near the surface is an indicator of rust traces, to treat curved or round objects or ones with buttons, rings or pins as an alarm, to leave ammunition where it is found and not take any of it home, and to mark the location and report finds to the police rather than move suspect objects, which can produce friction sufficient to trigger an explosion |
| Care and use, do not | Do not use to clear bushes or swing wildly or pry rocks loose; do not drop the machine into water or use it while raining or wet; do not leave it exposed at night where dew could form; do not store it where it could get extremely hot, including a car trunk; do not spray lubricants, cleaners, solvents or sealants onto the electronics; do not attempt to modify or repair the detector's electronics, which voids the warranty |
| Warranty exclusion | The warranty does not cover damage resulting from accident, neglect or abuse |
