sounds

A trowel, knife or small spade are good

tools for recovering targets.

Once a target has been located, clear the

surface of loose material and check again for

a signal. If there is no signal then the target

is amongst the surface material. In this case,

search the surface material until the target is

located. If the target is still in the ground, check

again with Pinpoint.

When digging, the aim is to leave the area of

ground exactly as you found it. Using a sharp

tool, cut a neat portion of grass or soil and

place it on a plastic sheet. This prevents the

material being scattered around and allows the

hole to be relled quickly.

Check the hole for the target. If it is not in

the hole, place the detector on the ground

with the coil at, pick up a handful of soil and

pass it over the coil. Be sure not to wear rings,

bracelets or a watch which will produce a

signal. Repeat this procedure until the target is

located.

Ensure that no other targets remain, then rell

the hole. All soil and portions of grass on the

plastic sheet should be returned to the hole

as neatly as possible. Step lightly on the soil to

compact it.

Leaving holes, or a scarred area, may result in

action being taken to prevent the use of metal

detectors. Please ensure that an area of ground

is left as you found it. Remove all rubbish.

Ask for permission before searching on

private property.

Threshold

This is the background ‘buzz’ given by the

detector to help distinguish between accepted

and rejected targets.

Blanking

When a rejected target is detected, the

Threshold sound ‘blanks’ (becomes silent) to

indicate that a rejected target is underneath

the coil.

Target Response

This is the sound given by the detector when a

target is located and not rejected.

In Coin & Treasure Mode, a target that is highly

conductive (e.g. a large silver coin) generally

causes a high tone beep and ferrous targets

generally cause a low tone beep.

In Prospecting Mode, a target signal will cause

an abrupt change in the pitch and volume of

the Threshold tone.

Pinpoint Response

When in Pinpoint, the detector emits a variable

tone, that increases in tone and volume as the

coil gets closer to the target.

Noise

A random, jittery sound indicates that the

detector is picking up external interference.

Sensitivity or Noise Cancel should be adjusted.

False Signals

Ground mineralisation can cause sounds

that can be mistaken for target signals. False

detections can be partial, random beeps (Coin

& Treasure Mode) or a continuous ‘warbling’

sound that diers from the sharper sound of a

real target signal (Prospecting Mode).

Start Up Sequence

When the detector is turned on there is a short

three note tune during its start-up sequence.

Positive Acknowledgement

The detector emits a short beep for

every valid key press.

Negative Acknowledgement

The detector emits a low double beep

to indicate an invalid keypress.

Completed

A three note tune indicates the completion

of a function (e.g. Auto Noise Cancel channel

calibration).

Patterns Erased / Factory Preset

A six note tune will announce when

these settings are complete.

Error

A six note tune will sound to indicate

a detector error (Error Messages, p. 49).

Overload

If the coil is passed across a large shallow

target or very highly mineralised ground, the

detector might give a repeating buzzing sound.

This indicates that the target signal is too

strong for the detector to interpret.

Low Battery Signal

When the battery power becomes low,

there will be a short announcement tune

(descending tones) every 60 seconds.

Low Battery Shutdown

A long announcement tune (descending tones)

will sound just before the detector shuts down.
