In response to many requests, the XP innovation team led by Alain Loubet has produced this concentric search coil in a spider design to complement the double-D series.
Compared to the double-D coil, the spider coil is significantly less susceptible to interference. In our tests, it was even possible to detect directly at a current changeover switch without interference.
The display behaviour is somewhat faster and more concise than with the 22.5 cm series coil, so the concentric spider has advantages especially with small metal objects. It is also easier to find the located metals below the coil. The swivelling speed is increased and therefore also the overall search speed.
Compared to the double-Dseries coil , the detection fieldis narrower towards the bottom, so that better separation of debris is possible.
