Pinpoint
The Pinpoint menu options allow you to choose between the two Pinpoint types:
• Normal
• Sizing
Normal
After activating the Normal Pinpoint function, the rst sweep over the target will
generate a wide audio response. With each successive sweep, the width of the
audio response will be automatically reduced until there is only a very narrow
response at the centre of the search coil indicating the targets location. Make a
mental note of the position, or mark a line in the soil with your shoe or digging
tool. Move to one side so that you can pass the coil over the target at right angles
(90 degrees) and pass the coil over the target again until only a narrow response is
heard. Mark the position again and X marks the spot.

Sizing
After activating the Sizing Pinpoint function the width of the audio response does
not change. Activating the Sizing Pinpoint as you near the target allows you to
manually control the width of the target response. Activating the Sizing Pinpoint
whilst the coil is away from the target and then approaching the target from
dierent directions allows the extent of the target to be determined.

NOTE
Changing the coil height during
Pinpointing can make the target
disappear altogether.
