IRON THRESHOLD
_______________________________
The GMAXX II is still a "multi-tone" detector, but users can
now adjust the iron level setting by using the IRON
THRESHOLD potentiometer.
This potentiometer can be seen as a discrimination setting with a
range only covering iron. It has fine-tuning settings ranging from 0 to
10.
At 0, all iron sounds at medium pitch. The higher the setting, the lower
the pitch for iron targets.
This, for example, enables small nails just to be picked up at a low
tone, whereas larger ones will be detected at medium tone.
As you will doubtless already know, too high a level of discrimination can
hinder the performance of a detector.
This setting was previously preset to be suited to the majority of users.
But most of the time, beginners do not want iron to register on their
machines, whereas more advanced users prefer to have this detection
option to make it easier to pinpoint coins on difficult terrain.
Use the Auto mode if you do not wish to worry you about the
setting of this potentiometer, it will allow you to have a
good rejection of ferrous targets & at the same time coke.
By default, the GMAXX II is a triple-tone detector, but users
can set it to double tone mode using the SILENCER switch:
Switch the SILENCER from position I to position II twice
within the space of two seconds. Your machine will then
be in Double-Tone LOW / MEDIUM mode or in MEDIUM Mono-
Tone mode if the IRON THRESHOLD potentiometer is set at
minimum, to go back to triple tone you will need to turn off
the detector & start again.
