SYMPTOM
SOLUTION
No power
1. Ensure batteries are installed in the correct orientation.
2. Replace all old batteries with all new batteries.
Erratic sounds or
target ID cursor
movement
1. Ensure your searchcoil is securely connected and the coil
cable is snugly wound around the stem.
2. If using the detector indoors, be aware that excessive
amounts of electrical interference exists, plus excessive
amounts of metal can be found in floors and walls.
3. Determine if you are close to other metal detectors or other
metal structures such as electrical power lines, wire fences,
benches, etc.
4. Adjust frequency
5. Reduce your sensitivity setting.
Intermittent Signals
Intermittent signals typically mean you’ve found a deeply buried
target or one that is positioned at a difficult angle for your
detector to read. Scan from different directions to help define the
signal. In the case of multiple targets switch to the ZERO Mode or
press the pinpoint button to precisely locate all targets. In trashy
areas, use the Super Sniper™ searchcoil. (NOTE: Iron targets may
cause Intermittent Signals. You can identify iron targets in ZERO
Mode) or with the Iron Audio feature.
I’m not finding specific
targets
Ensure you are using the correct mode for the type hunting you
are doing. If specifically hunting for coins, COINS mode should
be your best choice to eliminate other undesirable targets. You
may also use the ZERO mode, which detects all metal targets to
ensure desired targets are present.
Target ID Cursor
bounces
If your Target ID Cursor bounces erratically, chances are you’ve
found a trash target. However, a Target ID Cursor may bounce
if a good target (such as a coin) is not parallel to the searchcoil
(e.g. on edge). It may also bounce if there is one or multiple
“junk” targets laying next to the good target. Scan from different
directions until your Target ID Cursor becomes more stable.
NOTE: Large, flat pieces of iron—depending on their orientation
in the ground—can read as a good target or can cause erratic
Target ID Cursor movement. Use Iron Audio to help identify iron
targets.
Four bars indicate fully charged batteries. Replace batteries
when there is only one bar remaining. The detector will maintain
full performance until the batteries need to be replaced. NiMH
rechargeable batteries may be used, but may have a shorter life
per charge. You can expect 15-25 hours of operation without
wireless headphones, and 10-20 hours with wireless headphones,
depending on battery type and quality.
Access and replace the batteries by rotating the battery cover
housing one-quarter turn counterclockwise. Pull and remove the
cap to slide battery holder out. Remove batteries when the
AT Max
will be stored for longer than 30 days.
Note: 1.5V/cell Lithium batteries can also be used, but the use
of 3.7V/cell Lithium batteries will damage the detector.
