    OKM eXp 5500 Professional Multi-Sensor 3D Ground Scan and Individual Multi-Frequency VLF with Metal Discrimination 

    The OKM eXp 5500 Professional offers impressive depth performance for both shallow and deep metal detection thanks to the combination of VLF and 3D ground scanning technologies. This advanced mix allows precise measurements at various depths and expands the possibilities of exploring underground structures and finding precious metal artifacts in challenging terrains.

    • Multi-Sensor 3D Ground Scan and Individual Multi-Frequency VLF with Metal Discrimination
    • Detection Depth: With this technology customers can find objects down to 25 m (82 ft) deep
    • Use Cases: Archaeology, Treasure Hunting, Cavity Detection
    • Operating Modes: 3D Ground Scan, Magnetometer, VLF Metal Detection
    • Detectable Objects: Artifacts, militaria, treasure chests, cavities, tunnels, jewelry

    PentaSense: The Multi-Sensor Scanning System with up to 5 Simultaneous Super Sensors

    The PentaSense System is an advanced multi-sensor system whose 10 sensors take over the function of 5 Super Sensors side by side to perform high-resolution measurements on very wide scan fields. Thus, the eXp 5500 offers treasure hunters a new flexibility in terms of field and location requirements.

    PentaSense Rod: Ergonomic Handling For Best Scan Results

    Using the PentaSense Rod allows you to balance the probe ergonomically in front of you even on sloping terrain. Due to the greater distance between the probe and the detectorist, you can walk comfortably without having any influence on the measurement. In this way, you can achieve even clearer and more accurate scan results.

    Detect Treasures in Different Terrains

    The OKM eXp 5500 Professional is the ideal solution for exploring difficult terrain as well as wide areas fast and easily. Whether you use the Super Sensor separately or add sensor modules, called Enhancers, this 3D ground scanner adapts perfectly to different types of terrain, e.g. rocky mountain landscapes or vast desert areas.

    Super Sensor Configurations: 1 - 3 - 5

    The four interchangeable Enhancers can be plugged into any of the four Super Sensor sockets and thus allow for highest flexibility during assembly. With all four sensor modules, the PentaSense System is complete and allows you to scan the target area as if you carry five Super Sensors side by side simultaneously.

    Metal Detection with VLF Technology

    Very Low Frequency (VLF) allows detectorists to find metal objects in shallow soil. The VLF coil emits an electromagnetic field into the ground, which generates electric currents in buried metal objects. This creates its own electromagnetic field in the target objects, which can be detected by the eXp 5500. VLF metal detectors are particularly efficient at locating a variety of metals, including artifacts, relics, militaria, coins, and jewelry.
