Pinpoint

Pinpoint
Pinpointing narrows down the location of a buried target, allowing you to
determine its exact location before digging.
Normally the CTX 3030 is a 'motion' detector; it must be moving over a target
in order to detect it. When Pinpoint is activated, the CTX 3030 will operate as a
non-motion detector, producing a constant audio response while the coil is held
still over a target. Pinpoint instructs the detector to temporarily disengage the
Discrimination Pattern, thereby allowing the detection of all targets underneath the
coil. Detection results, such as FE-CO coordinates and depth, are still updated.

Activate Pinpoint

Activate Pinpoint by holding the Trigger from the Detect or Map screens.
When Pinpoint is activated, a gauge will appear at the bottom of the detection
screen. This gauge will move from the outsides to the centre as the coil is moved
closer to the target.

The audio response to the target will also change; both pitch and volume will
increase as the coil approaches the target.
Pinpoint the Target
1. Once the approximate target location is known, move the coil to one side of that
location and press and hold the Trigger.
2. Sweep the coil slowly across the target location keeping the coil parallel to the
ground while holding the Trigger.
3. Taking note of the response, locate the centre of the target by listening for the
loudest signal or watching the red ball on the Pinpoint Gauge. 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 (Figure 22).
Repeating steps one to three in the new direction will give an exact location to dig.
