Thanks to its 4,6 kHz search frequency, the G-Maxx is a powerful and versatile detector for coins and large objects in various types of ground. An important flexibility in the set up of discrimination adjustments allows you to fit in with the ground you wish to detect, thanks to the new Multi-Tone mode and the IRON LEVEL adjustment. The Gmaxx has instantaneous signalling, rather than a LCD display because of the extraordinary analysis of the human ear compared to an LCD display. LCD displays cannot respond in real time and do not capture weak signals that are too brief or too close to other signals.
