PI metal detectors like the OKM Pulse Nova are perfect for starting the treasure hunting adventure thanks to its easy handling. They are also used for gold prospection and are used by explosive ordnance disposal services. The Pulse Nova pulse induction detector offers different search coils, providing good detection and depth performance when searching for natural gold, coins, jewelry and militaria.
Special Features of Metal Detector Pulse Nova:
- Detection depth up to 3 m (9.8 ft)
- Fast scanning of large areas
- Easy localization of objects (Pinpointing)
- Also suitable for use in densely vegetated areas
- Also suitable for use on heavily mineralized ground (including salt water)
- Ignores most unwanted small items like aluminum foil
- Interchangeable search coils
- Waterproof search coils for gold prospecting in shallow waters

How the PI Metal Detector Works
Simply switch on the metal detector, start walking and swivel! But that’s just where the real work begins in the Pulse Induction Detector. After plugging in the desired coil, the Pulse Nova automatically identifies it and starts the appropriate processes for your successful treasure and gold search.
How the PI Detects Metal Objects
The Pulse Nova pulse induction detector follows the principle of a time-controlled oscillator that uses an alternating current to generate a magnetic field in a coil. This is sent into the ground and generates an eddy current and thus a reaction in the buried metal object. The resulting electrical conductivity in the metal object is detected by the Pulse Nova as a “disturbance” – i.e. an anomaly – and reported by acoustic signals.
In this way, jewelry made of precious metals such as gold and silver, but also ferromagnetic objects as well as natural gold minerals and gold nuggets can be detected directly.
Targeted Search with Pulse Nova
Thanks to the way it works and the different coils, treasure hunters can focus well on their target objects: With the large search coil as well as the Frame Coil Xi104, small objects such as bottle caps, pull tabs and small pieces of aluminum foil can be ignored. But beware: Even single coins cannot be displayed when using the large search coils! Depending on the application and target object, make sure to select the appropriate coil:
- Large search coil, large magnetic field: mainly larger metal objects can be found.
- Small search coil, small magnetic field: Smaller objects can also be detected.
Metal Detector with Intuitive Operation
Clearly Structured Control Panel
The Pulse Nova is able to locate buried metal objects in various soils without having to excavate the area first. Thanks to the ease of use of the PI metal detector and its interchangeable search coils, results can be obtained quickly and easily.
The control unit has two rotary knobs for adjusting sensitivity and volume. For a particularly intuitive and language-independent operation, a display was completely omitted. Acoustic feedback informs the user directly via loudspeaker or Bluetooth headphones about detected metal objects.
Telescopic Rod for Convenient Use
The Pulse Nova PI detector is supplied with a telescopic rod. This has an adjustable armrest so that the metal detector lies comfortably and balanced in your hand. The length of the linkage can be adjusted.
In just a few simple steps, a control unit and a flashlight can be attached to the telescopic rod at the top. At the lower end, the desired search coil is attached. Only the frame coil is not used with the rod.
Pinpointing with the PI Metal Detector
Once the metal detector has found an object, it is time for pinpointing: First, with slow sweeping movements above the object, the exact position is determined. Gradually narrow down the point of the anomaly by continuing to slowly swing the metal detector from different directions over the detected anomaly. An intense audio signal indicates the exact position and size of the object.
