OKM eXp 5500 Professional: The Ultimate 3D Ground Scanner

The OKM eXp 5500 Professional delivers exceptional depth performance, effectively locating both shallow and deeply buried targets. Its unique fusion of VLF and 3D ground scanning technologies provides the precision needed to explore complex underground structures and unearth valuable artifacts in even the most challenging environments.

Revolutionary PentaSense Technology

Introducing the revolutionary PentaSense System, a multi-sensor array that utilizes 10 sensors to create a five-in-one super-sensor configuration. This technology enables high-resolution measurements across incredibly wide scan fields, providing treasure hunters with unprecedented flexibility to adapt to diverse locations and terrains.

The PentaSense Rod enhances your scanning experience by providing superior ergonomics. Its design allows you to comfortably balance the probe, even on uneven or sloping ground. The increased distance between the user and the sensor minimizes interference, ensuring you capture cleaner, more accurate scan data for optimal results.

Unmatched Versatility & Customization

The OKM eXp 5500 Professional is built for versatility, making it the perfect 3D ground scanner for quickly and easily surveying both wide-open spaces and rugged, difficult terrains. With the ability to use the Super Sensor alone or expand its reach with modular Enhancers, this system excels in diverse landscapes, from rocky mountains to vast deserts.

• Modular Super Sensor Configurations: 1 - 3 - 5 Achieve maximum scanning flexibility with four interchangeable Enhancer modules. These modules seamlessly connect to the Super Sensor, allowing you to configure your system for a variety of tasks. When all four modules are attached, the complete PentaSense System works as if you are scanning with five Super Sensors at the same time, covering vast areas in a single pass.

  • 1 Super Sensor: Ideal for detailed, specific scans in confined spaces like caves, crevices, and narrow passages.

  • 3 Super Sensors: By adding two Enhancers, you can expand your scanning width to cover more ground efficiently.

  • 5 Super Sensors: The full PentaSense configuration, with all four Enhancers, enables you to survey wide fields rapidly and with high resolution, ensuring you don’t miss any potential targets.

Advanced VLF Metal Detection

The integrated VLF metal detection mode is designed for finding objects in shallow ground. By transmitting an electromagnetic field into the soil, the eXp 5500 induces a detectable current in buried metal targets. This technology is highly effective for locating a wide range of valuable items, including ancient artifacts, historical relics, coins, jewelry, and militaria.

The proprietary VLF search coil technology of the eXp 5500 PentaCoil enables advanced metal discrimination. This crucial feature allows treasure hunters, archaeologists, and prospectors to distinguish between valuable metals like gold and silver and less desirable targets such as iron and bronze. This precision significantly boosts your efficiency and accuracy, helping you focus on the finds that matter most.

The VLF Metal Detection mode on the eXp 5500 features two innovative tools: Multi-Frequency and customizable Target-ID Zones.

• Activated Target-ID zones provide clear visual feedback and an audible signal, while also displaying the maximum value detected, for instant target identification.

• To prevent you from missing a potential valuable find, objects in deactivated Target-ID zones are not fully ignored; they are displayed with a faint visualization, ensuring you remain aware of all possible targets.

The eXp 5500 comes with pre-programmed scan profiles optimized for common target objects. These profiles automatically filter out unwanted Target-ID ranges, allowing you to focus on the items you seek. Additionally, each profile is assigned the ideal frequency channels to ensure peak detection performance for that specific type of target.

For total control, you can also create a custom scan profile. This feature allows you to select single or multi-frequency ranges based on your unique experience and local conditions, such as highly mineralized soil or varying levels of moisture. You can also fine-tune the sensitivity to adapt to the ground’s mineralization or the density of junk metal, ensuring a perfect scan every time.

Professional Features for Peak Performance

The Super Sensor of the OKM eXp 5500 Professional features the intuitive LED Orbit display, a favorite among users of the OKM Rover C4. These LEDs provide real-time visual feedback on buried targets, giving you immediate insight into what lies beneath the surface.

The included Open-Ear Headphones are a game-changer for field work. Their lightweight design lets you hear crucial detector signals while remaining fully aware of your surroundings. This enhanced situational awareness is particularly valuable in busy or challenging environments, ensuring both safety and success.

With a modern USB-C port, the eXp 5500 offers fast data transfer and convenient charging. Once your scan files are moved to a Windows notebook, you can conduct a comprehensive analysis using the included Visualizer 3D Studio Professional Edition software.

The intuitive Control Unit features a responsive touchscreen and a multi-lingual interface, making operation simple and direct. The display has been upgraded for superior readability, even in bright, direct sunlight.

More than just for data transfer and charging, the integrated USB-C port is also your gateway to the latest features. It allows for quick and easy firmware updates for both the Control Unit and all probes, ensuring your detector always has the most current technology and functionality.

The user-replaceable battery design is a testament to the long-term reliability and sustainability of this OKM detector.
