All Metal Mode - Teknetics T 2+ Comprehensive Operating Manual & Manual

ALL METAL MODE

The All Metal Mode is more sensitive and offers better feel than the Discrimination Mode, and
is used to find all metal objects present in the ground. The searchcoil must be in motion for
objects to be detected. This is a single filter search mode similar to the "fast Auto-Tune",
"SAT", or "P4" Mode found in other detectors you might already be familiar with.
SENSITIVITY
This controls the electronic gain, and is adjustable from 1 to 99. In the
presence of electrical interference, high ground mineralization, or variable ground
mineralization, operation will usually be too noisy (wobbly and erratic sound from the speaker)
if the sensitivity is set too high. At settings above 90, the internal circuit noise of the machine
will probably be audible. The sensitivity level setting is largely a matter of personal
preference. However, if you cannot hear at least some noise, the smallest or deepest objects
will not be detected.
HUM LEVEL
This is the same thing that some manufacturers call audio threshold. It is
adjustable from -9 to +9. For maximum ability to hear the weakest signals, adjust this
background hum level high enough so that it is barely audible while the detector is in use in
the field. To eliminate the weakest signals, adjust the hum level into the negative region,
which will allow the machine to run silently if the Sensitivity is not set too high.
The hum level changes slightly with each detent step on the Settings knob. Each number on
the hum level numeric readout corresponds to five steps.
Manual Ground Cancellation can only be performed while in the All Metal Mode, but the
MANUAL GROUND CANCELLATION
resultant setting will carry over if you change into Discrimination Mode. See the previous
section on Ground Cancellation for instructions on how to use this feature.
When # OF TONES in the DISCRIM menu is set to bP, the response characteristics of All
bP: BOOST
Metal Mode also change.
Using bP, the T
is more sensitive to larger, more deeply buried gold nuggets.
2+
Using bP, if you sweep too fast, you risk not detecting the smallest gold nuggets on the surface.
Maintain a slow sweep speed.
