The Imp is an accurate, dependable metal detector for a variety of industrial applications. It uses radically different pulse induction eddy current technology for high stability and immunity from false signals.
With pulse induction, the detection head only needs to contain one search coil, whereas other methods of metal detection require two or even three coils.
These coils have to be balanced for such instruments to work properly and any slight contraction or expansion of the search head due to temperature changes -- eg by moving from strong sunlight to shadow -- means they need to be re-balanced.
This balancing requires a number of different knobs while Protovale's instruments do not require constant re-tuning and can therefore work with just one control knob.

Its controlled sensitivity and strongly directional head allow it to be used close to barbed-wire fences, metal buildings and parked cars. The signal cuts off sharply when the Imp has passed beyond the object; allowing the operator to identify the precise shape.
The Imp is deep-seeking, lightweight and strong, as well as being easy to use with its one control knob and is field-proven, having been used by all UK water companies and many others around the world.

(and for veterinary purposes)
The Versatile Imp is field-proven in the timber industry for finding metal in raw timber. Lightweight and rugged, the Imp pinpoints the exact location of the metal and stays accurate in all conditions. Its stable signal allows the positive identification of metal in difficult environments.
Easy to use, with only one control knob, the Imp has interchangeable heads for multiple applications, from sawmills and timber reclamation to veterinary uses.
The Imp uses unique pulse induction technology for stability of signal in all temperatures and, unlike other metal detectors on the market, does not require retuning.
It is not affected by the medium through which it searches and give precise location through wood, concrete and air, irrespective of the temperature or salt content.
