Pinpointing Technique
Switching to Pinpoint when you nd a target activates the
target signal strength visualisation on the Discrimination Scale
to help you accurately locate the buried target.
The Pinpoint button
Pinpoint progressively masks the Target response by reducing
the Sensitivity with each sweep until only a very narrow target
response remains. This helps identify the exact location of the
target.
In Pinpoint, the detector's response indicates the strength of the
target signal directly below the coil. The Pinpoint audio
response is tone and volume modulated. The di erence in
tone and volume will help to locate the position and depth of
the target.

will appear in the lower left corner of the LCD
②.Sweep the coil slowly across the target location keeping the
coil parallel to the ground.
③.Taking note of the response, locate the centre of the target
by listening for the loudest signal and/or watching the
Discrimination Scale on the LCD.
④.The value in the center of the screen represents the distance
between the target and the coil。
Pinpointing a Target Manually
1. Sweep the coil slowly across the target location keeping the
coil parallel to the ground.
2. Locate the centre of the target by listening for the loudest
target signal response.
3. Make a mental note of the position, or mark a line on the soil
with your shoe or a digging tool.
4. Move to one side so that you can pass the coil over the target
at right angles to your initial direction.
5. Line up the target at 90° from the initial direction and repeat
the process. The object is located where the two imaginary lines
cross.
