OKM GeoSeeker Professional Water and Void Detector

The OKM GeoSeeker is a professional geoelectrical water and void detection system designed to investigate ground-resistivity patterns that may indicate water-bearing formations or cavities. OKM specifies exploration depths up to 250 meters (820 feet) under suitable conditions; this maximum is not a guaranteed result at every site.

• Professional Geoelectrical Technology: Measures ground resistance and soil resistivity using a Schlumberger-based geoelectrical measurement procedure
• Detection Depth: Manufacturer-stated maximum exploration depth: 250 m (820 ft) under suitable conditions; achievable depth and resolution vary by site and survey setup
• 3D Data Visualization: Displays measured values in detailed 3D graphics for easier interpretation
• Primary Applications: Water detection, cavity detection, groundwater exploration, geotechnical engineering, and land investigation
• Operating Modes: Active Scan and Passive Scan
• Detectable Structures: Fresh water, groundwater levels, water-bearing gravel, caves, tunnels, chambers, cavities, voids, and underground barriers

Water and Void Detection Down to 250 Meters

The OKM GeoSeeker is designed for professionals searching for underground water resources or hidden void structures at extreme depths. By measuring the apparent resistivity of the ground, the system can identify underground formations that may indicate water deposits, water-bearing gravel, groundwater levels, or underground cavities.

This makes the GeoSeeker an excellent choice for water well planning, land development, geological investigation, geotechnical surveys, and advanced exploration projects.

Active and Passive Scan Modes

The GeoSeeker supports multiple scan modes to match different detection needs and ground conditions.

Active Scan - Accurate

In Active Scan Accurate mode, the system uses two electrodes to inject electrical power into the ground while two additional electrodes measure the voltage difference at specific scan points. This information is used to calculate the ground resistivity.

This mode is ideal for detecting underground water deposits, hidden caves, cavities, impervious layers, and underground barriers. Users can define a specific scan depth range between 5 meters and 250 meters.

Active Scan - Quick

Active Scan Quick is a faster version of the accurate scan. It also injects electrical current into the ground and measures the voltage difference to calculate soil resistivity, but is designed for quicker field surveys.

Passive Scan

In Passive Scan mode, the GeoSeeker uses two electrodes to read naturally occurring underground voltage without injecting electrical power into the ground. This mode is used specifically for detecting underground flowing water.

Android Tablet Control and Easy Scan Setup

The GeoSeeker is controlled wirelessly through a modern Android tablet using the pre-installed GeoSeeker application. Commands and measurement results are transferred via Wi-Fi, allowing simple and efficient field operation.

The app provides step-by-step graphical instructions to guide the user through the entire measurement process. Supported scan options include:

• Single Measurement
• Complete Measurement of a rectangular field
• Lengthwise Measurement of a single line
• Crosswise Measurement of a single line

3D Scan Results and Visualizer 3D Studio Analysis

After the measurement is complete, the GeoSeeker displays a 3D representation of the measured ground resistivity values directly on the tablet screen.

Color adjustments help visualize the measured data. In OKM's display scheme, blue may represent potentially conductive water-bearing zones, while reddish colors may suggest resistive structures or layers. These colors are interpretation aids, not proof of freshwater, a cavity, or a particular geological material.

GeoSeeker scan data can also be analyzed in OKM Visualizer 3D Studio Professional Edition. With advanced 3D rendering tools, users can review, optimize, and interpret scan results in greater detail.

Portable and Field-Ready Design

The GeoSeeker hardware is packed in a waterproof and shock-resistant Protector case, making it easier to transport and protect during field use. This rugged design helps keep the system organized, secure, and ready for professional exploration work.

Interpreting Results Before Drilling

Electrical resistivity is influenced by clay content, salinity, moisture, and geological conditions. Different subsurface materials can produce similar readings. Survey results therefore require interpretation alongside local geological information and, where appropriate, independent verification.

A GeoSeeker survey does not guarantee groundwater, a productive well, a particular yield, or potable water. Confirm drilling decisions with a qualified groundwater professional; determine water quality through appropriate testing.
