SENS Adjustment (contin-
ued)
5. While using a steady slow search coil sweep
speed, simultaneously advance SENS towards
"100". If the "OVERLOAD-REDUCE SENS/
LIFT LOOP" alert keeps popping up on the
display, or if ground noises make it difficult to
recognize metal targets, reduce SENS counter-
clockwise.
6. The trash I.D. capability of the M6 also func-
tions more accurately when the SENS is set at a
level which allows for smooth operation. Too
much SENS can cause bad ground to distort the
proper identification of iron and non-iron targets.
7. Note: It is normal to hear changes, clicks or soft
beeps, coming from the audio (speaker) during
SENS adjustments as the circuit shifts between
hardware and software SENS (different electrical
parts of the circuitry). The SENS control adjusts
both the hardware SENS (physical component) as
well as the software SENS (computer code) alter-
nating between the two throughout it's range. As
the M6 shifts between these two intricate parts of
the circuitry an audio indication notes the transi-
tions. This can be helpful. If you adjust the SENS
slightly, the audio notes a significant rather than
slight change.
8. The M6 provides more SENS control range than
is typically useful. Few areas will allow maximum
SENS (full clockwise) without at least some noisy
operation. Settings in the 100+ area require a high
degree of operator skill and patience.

(continued)
If, of course, "OVERLOAD-REDUCE SENS/
LIFT LOOP" message is displayed, common for
very nasty ground mineralization, you must heed it
and reduce the SENS rather than raise it.
3. If the ground is highly mineralized, SENS set-
tings well below this initial triangle may be neces-
sary to identify metal items, and will still provide
ample detection depth.
4. In addition, any increase in SENS adjustment
should NOT BE at the expense of maintaining
predictable results without false signals, beeps and
static from bits of mineralization (erratic behavior).
