Iron Check
Use this feature to audibly identify iron targets. Iron
Check only works with DD searchcoils and will not work
with mono coils. If the Iron Check button is pressed
while using a mono coil, a repeating warning alarm will
indicate this to be an invalid action.
To Utilize Iron Check:
• Move the searchcoil to the side of the target.
• Press and hold the IRON CHECK button and wait
for a double-beep.
• Then continue holding the IRON CHECK button
while repeatedly scanning back and forth
completely past the target with very flat, level
swings.
• If desired, check the target again from different
directions by rotating around 90 degrees. Main-
tain very flat, level swings over the target.
• Iron will produce a very low-tone buzz
sound that may or may not be flanked by normal
tones.
• Non-ferrous and/or weak targets will produce
normal tones, or may even be silent, but typically
won’t produce the iron tone (buzz).
Note:
Iron Check is a conservative function. To help
ensure
Axiom
does not misidentify a good target as iron,
the iron tone (buzz) will only activate on strong signals.
Therefore, small/weak iron targets may not identify as
iron. In addition, due to their large, flat surface area and
relatively high conductivity, steel bottle caps will typi-
cally not identify as iron.
Examples of iron targets that will produce the iron
tone (buzz) are: a 3-inch nail to a depth of about 5
inches; and a ¾-inch boot nail to a depth of about 2
inches. In highly mineralized areas, Iron Check accuracy
may be affected. Therefore, it is very important to use
flat, level swings to improve accuracy.
Press and hold IRON CHECK to use this function.
Indicates IRON CHECK is on.
