  • quick and easy setup and operation
  • exchangeable probes of various purposes
  • color-coded surveys
  • immediate on-site interpretation of target area
  • measured values show extreme depth of survey
  • measured values show location of targets within surveyed area
  • highly sensitive and accurate metal detection

Multi-purpose Detector with Exchangeable Probes

eXp 4500 components

The high-performance detector eXp 4500 features interchangeable sensors that have been tuned and optimized for their specific purpose and function. As a result, the lightweight and simple-to-use treasure detector is ideal for treasure hunters looking for a variety of treasures.

The eXp 4500 Light comes with the following accessories:

High-resolution ground scans, pinpointing, and mineral detection are all possible with the Super Sensor.
Additional specialized probes can be added:

Tunnel Sensor with GPR Antenna (25cm, 50cm, 75cm, 100cm)


Easy-to-use Detector for all Treasure Hunting Levels

eXp 4500 in use

Archaeologists, gold seekers, and treasure hunters can use the treasure detector to:

  • carry out 3D archaeological surveys and metal detection
  • pinpoint the exact location of buried treasures and relics, visualize discoveries and underground structures in 3D images including size and
  • depth, and detect gold, silver, bronze, and other valuable objects
  • Discover ancient artifacts, hidden treasures, coins, treasure troves, and pirate chests.
  • Explore tunnels, voids, and caverns in search of gold minerals and natural gold.



eXp 4500 Scan Modes

Discoveries and treasure finds come in all shapes and sizes, and are made of a variety of materials. As a result, treasure hunters who are not specialized in a particular type of find require a variety of operating modes and locating methods to locate all types of hidden treasures at various depths beneath the surface.

The eXp 4500 Light ground scanner has the following scan modes:

  • Ground Scan: ideal for treasure hunters and archaeologists in search of underground artifacts, treasures, and historical objects.
  • Mineral Scan: enables gold prospectors and gold seekers to be more successful in natural gold mineral panning.
  • Pinpointer: aids treasure hunters in determining the exact location of detected items.
  • Magnetometer: aids in the detection of ferrous metals such as iron and steel.



Visualization of Treasure Finds and Discoveries

3D visualization

The eXp 4500 sensors are directly connected to the control unit, which displays the measurement data on the full color screen immediately. These data can be saved in the device’s internal memory and then transferred to a computer.

On a computer, the specialized software Visualizer 3D allows for the evaluation and comparison of all stored data. The user can also determine the depth, size, and position of detected structures and objects.
