Backlight, Speed, and Sensitivity
Backlight
Press the MENU button until the Backlight icon is
selected, then press the MENU Plus (+) or Minus (-)
buttons to switch on or off the LCD backlight, for
searching at night or in low-light situations.
Note: As a convenience, the backlight will automatically
activate when scrolling through the menu, regardless of
the backlight setting. It will return to its selected setting
once the menu is exited.
Speed
This adjustment refers to the speed at which you scan
the coil as well as target recovery speed, also known
as Reactivity. Set the Speed adjustment according to
your preferred scanning speed, target recovery speed/
reactivity, and EMI noise conditions as described below.
Press the MENU button until SPEED is selected, then
press MENU Plus (+) or Minus (-) buttons to choose
between Slow, Medium or Fast scan speeds.
SLOW: This setting will produce the smoothest and
quietest operation thereby ensuring excellent depth and
sensitivity, but will require a slow coil swing and will have
less ability to separate adjacent targets due to slower
reactivity.
MED: This is the default setting and should be used
as a general-purpose selection for moderate coil swing
speed. This setting will also provide increased ability to
separate adjacent targets due to its medium reactivity.
You may notice an increase in EMI and noise chatter
compared to the SLOW setting, but will still provide
good depth and sensitivity.
FAST: This setting allows a faster coil swing to search
an area more quickly and will have increased ability to
separate adjacent targets due to faster reactivity, but
may also increase EMI and noise chatter, making it more
difficult to discern faint targets.
Sensitivity
Use the SENS Plus (+) or Minus (-) buttons to select one
of eight (8) Sensitivity levels. Default setting is 6.
Use increased sensitivity when searching for very
small or very deep targets. Use lower sensitivity levels,
as needed, when the detector is behaving erratically
(due to excessive metallic trash, highly mineralized soils,
electrical interference or the presence of other metal
detectors) and the erratic operation cannot be resolved
with Ground Balance or Frequency Scan.
When Backlight icon is highlighted, use the Plus / Minus
Menu buttons to switch on or o.
When SPEED icon is highlighted, use the Plus / Minus
Menu buttons to select desired coil swing speed.
Use Plus / Minus SENS buttons to select desired sensitivity.
Note: The Axiom is a very high-performance
detector. The upper Sensitivity settings (7 & 8) are
extremely sensitive and may not be suciently
stable for many users and conditions. These extreme
Sensitivity settings are designed for experienced
users accustomed to operating their detectors at
the very limits of marginal stability in order to obtain
maximum possible performance.
