The Sensitivity and Volume/Vibration settings in the Pinpoint UI are separated from the Main
Detection UI. This separation ensures that while the main detection Sensitivity and
Volume/Vibration are set for general detection, the pinpoint Sensitivity and Volume/Vibration can
be finely adjusted for the accurate location of metal targets.
Pinpoint is a non-motion mode where the coil doesn't have to move to indicate a target. The
detection signal gets stronger as the coil approaches the target, causing the audio (if audio output is
on) or vibration (if vibration mode is on) to intensify. In Pinpoint mode, the detector tracks the
target signal peak. When the target signal reaches 90% of this peak, the pinpoint icon on the top
centre of the LCD screen will flash, helping users centre on targets more efficiently. If the coil is
moved off the target and the signal volume decreases, the flashing stops. Moving back over the
target resumes the flashing. As mentioned, pressing the Left/Pinpoint Button retunes the detection
threshold due to ground variation or temperature drift. Pressing this button also resets the target
signal peak to zero.
The Conductive Target ID (0-99) displayed in the Pinpoint UI remains stable even in highly
mineralised soils. Generally, a higher number indicates a larger or more conductive target. To obtain
an accurate target ID, it is recommended to follow these steps:
Move the coil away from but close to the target.
Ensure the coil is resting on the ground surface and press the Left/Pinpoint button to
retune.
After that, slide the coil on the ground surface until the target is positioned just below the
centre of the coil.
The conductivity target ID is also useful for assessing the target's shape. If the target ID fluctuates
significantly when the coil is moved slightly off but still above the target, it likely indicates an
irregularly shaped target, such as a bottle cap or a nail with a large head.
There are three audio settings within the pinpoint mode: Classic Tones, 5 Tones and 100 Tones.
Users can seamlessly switch between audio settings by briefly pressing the Right/Auto GB button
while in pinpoint mode.
Classic Tones:
In Classic Tones audio setting, audio pitch correlates with signal strength, with higher pitches
indicating stronger signals. Tailored for precise pinpointing of target locations.
5 Tones:
Audio pitch is determined by conductivity target ID, providing distinct audio feedback for different
target ranges. Conductivity target ID ranges 0-19, 20-39, 40-59, 60-79, and 80-99 correspond to
audio pitches of 330Hz, 490Hz, 650Hz, 810Hz, and 970Hz, respectively.
5 Tones Inv.:
Audio pitch varies by conductivity target ID in reverse order. Conductivity target ID ranges 0-19, 20-
39, 40-59, 60-79, and 80-99 correspond to audio pitches of 970Hz, 810Hz, 650Hz, 490Hz, and 330Hz,
respectively.
