Pulse Nova metal detector is a new product from OKM, Germany released in 2021.
Pulse Nova uses new enhanced pulse induction (PI) technology , famous for better performance
and more depth reach underground up to 3 meters , with more reliable results in comparison with
OKM Pulse Nova is a perfect choice for amateur and beginner prospectors as it is easy to handle
and use metal detector with minimum controls but with professional-level performance in all terrain.
Pulse Nova Features
Multi-Purpose Metal Detector
Pulse Nova is a multi-purpose device fit all needs of prospectors
and can be used in different applications including:
- Coin shooting of ancient coins made of gold or silver or other metals
- Natural gold prospecting including detection of gold nuggets and gold veins
- Treasure detection of artifacts and ancient buried metallic objects.
- Jewelry detection such as rings, golden collars, earrings and so on.
Pulse Nova works using a pulse induction technology with a search coils with one coil
for sending and receiving magnetic field signals.
Pulse Nova metal detector use a time-controlled oscillator principle, here it use an alternating current
for generation of magnetic field inside the coil, the generated field transmits into the ground generating
an eddy current that react with any buried metallic object changing its electrical conductivity properties,
the change lead to creation of reflected magnetic field which detected by coil as an anomaly, the received field
interact with coil and converted into a digital signal that converted into acoustic signal and audio output via device speakers.
The device includes a special pinpointing mode using a slow sweeping of search coil
above possible target , the accurate exact position of this target can be determined
by sweep of coil from different direction over detection area and hear the audio signals
if it reached to an intense level that mean the target is very close to search coil.
Search Coils for Different Targets
Pulse Nova comes with one search coil: delta search coil (38 cm diameter) and prospector
can buy optionally other search coils including Omega coil (38 cm diameter),
small 18 cm coil or frame coil with 4 pipes with 1 m length for each pipe.
Each search coil can be used for specific purpose depending on size of buried targets:
- Small 18 cm coil: best to find small size objects such as single coin or small relics at small depths.
- Delta or Omega coils: suitable to detect larger metal objects such jar of coins at greater depth
- Frame Coil: best for detecting of very large objects at more depths, for example golden chest or big-size coffin
See following table for reference:

|Gas can 20 l||115 cm||180 cm||255 cm|
|Steel barrel DIN EN 210||115 cm||180 cm||310 cm|
Pulse Nova metal detector can be adjusted very easily with minimum controls, as the device
control panel contains just two rotary knobs , one for setting the sensitivity value and the other
one for audio volume adjusting ,
The device has no display screen, here in Pulse Nova the concentration was on acoustic
feedback via audio output across built-in speaker or user use Bluetooth headphones
to hear audio tones related to detected objects
Waterproof Search Coils
The search coils of Pulse Nova are waterproof and therefore can be used to search for lost metal targets
near the shores of the seas or rivers in shallow water (example gold prospecting in rivers).
Telescopic Rod for Convenient Use
Pulse Nova PI detector is supplied with a telescopic rod, It has an adjustable armrest so that the device lies
comfortably and balanced in user’s hand, it is possible to adjust the length of the linkage.
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.
