The probe is manufactured with new technology and its processing is top-notch. The probe is designed for searching in all types of soils. Its very good properties stand out in areas with ferromagnetic rocks. We had the opportunity to test the coil in places where small ferrous objects were attaching themselves to the rocks and the probe was still able to detect even small coloured targets. We have to say that the improvement in such locations was really impressive.
In sites with standard mineralization, the difference between the classic 9" that comes standard with both the LP ZERO 23 and the GM4PRO 9" is smaller. Thus, we can highly recommend the probe to all those who work in basalt localities. The improvement in the behaviour of the LP ZERO and GM4PRO metal detectors is really noticeable and the coil is definitely worthwhile in such places.
The probe is designed for frequencies from 13 to 18 kHz and LP ZERO, LP ZERO II and GM4PRO detectors. The coil size is 9.5" (24 cm), 2D technology and fully waterproof. Thanks to the new manufacturing technology, the coil is also nicely lightened and the weight is only 409 g. (without cap 373 g.) The probe comes standard with a protective cover.
