1. Introduction
The OKM Rover UC is a sophisticated ground scanner designed for detecting underground anomalies, including metals, cavities, and archaeological artifacts. This device is engineered for both novice and experienced users, offering advanced detection capabilities in a discreet, walking stick form factor. It operates wirelessly, controlled by an Android smartwatch, providing a user-friendly interface for data analysis.

2. Product Overview
The Rover UC system integrates a wireless telescopic probe, which functions as the primary sensor, with an Android smartwatch that serves as the control unit and display. This design ensures portability and ease of use during field operations. The smartwatch displays real-time scan data and allows for mode selection and settings adjustments.

3. Setup and Assembly
- Charging: Ensure both the wireless telescopic probe and the Android smartwatch are fully charged using the provided charger and cables.
- Probe Extension: Extend the telescopic probe to a comfortable operating length. The probe is designed to be adjustable for various user heights.
- Power On: Power on the telescopic probe and the Android smartwatch. Refer to the respective device manuals for specific power-on procedures.
- Bluetooth Pairing: On the smartwatch, navigate to the Bluetooth settings and initiate a search for available devices. Select the Rover UC probe from the list to establish a connection. The connection range is up to 26 feet (8 meters).
- Software Initialization: Once paired, launch the OKM Rover UC application on the smartwatch. The system will perform an initial check and prepare for scanning.
4. Operating Modes
The Rover UC offers three distinct operating modes to cater to various detection requirements:
- 3D Ground Scan: This mode is used for visualizing underground artifacts and cavities. It generates a three-dimensional representation of the subsurface, allowing for detailed analysis of detected anomalies.
- Pinpointer: The Pinpointer mode assists in precisely identifying and localizing detected objects. This is crucial for narrowing down the exact position of a target before excavation.
- Magnetometer: This mode is specifically designed for the localization of ferromagnetic objects. It detects variations in the Earth's magnetic field caused by buried iron or steel objects.
- Vibration: An optional vibration feature can be activated via the application's settings menu, providing tactile feedback upon detection.

5. Use Cases
The OKM Rover UC is suitable for a variety of applications:
- Treasure Hunting: Locating buried coins, jewelry, and other valuable metallic objects.
- Cavity Detection: Identifying hidden tunnels, chambers, caves, and other underground voids.
- Archaeology: Assisting in the discovery and mapping of ancient structures, artifacts, and burial sites.
- Militaria Detection: Locating historical military objects, such as unexploded ordnance or buried equipment.
