The Detector in this mode will try to select the highest sensitivity possible without
too much chatter, but I find that manual adjustments are much better for quiet sites,
use Auto when on highly mineralised ground etc.
Always upon arriving at your site, switch on the Detector with the coil on the
ground (away from any metal) and press and hold in till “Noise Cancel starts”
this optimises the detector, sets the frequency and ground balances the machine.
Only use “In Air” when near other users or near
Overhead Power Lines to mask out airborne interference.
I recommend using the “Noise Cancel” function every 30 minutes or so when detecting,
as ground effects can change within the same field. Regularly doing Noise Cancel
helps you keep the machine working at its best. See No 3 Above.
Always adjust the Threshold so that you can just hear a slight hum,
you will then be able to hear when it goes silent, this silence occurs
when the search head has passed over ferrous targets or targets that are discriminated
out in the quick mask / reject area.This silence is called a “Null Point” and
when this occurs slow down your search head sweeping speed, as you maybe missing
In high trash areas that are being nulled out, this kind of searching also needs
Recovery set to: FAST. For Fast Recovery in null areas.
