You can search silently or at any level of constant

sound. It is recommended that you always operate

the instrument at a minimum level of sound. You can

hear the audio increase sharply whenever a target

is encountered.

Also, you will be able to hear even the faint signals

that sometimes occur on tiny targets or deeply

buried coins. When headphones are used, it will

usually be necessary to decrease the threshold level

since sound is more audible through headphones.

After you have made audio adjustments, press

AUDIO to re-enter your previous operating mode.

The

GTAx 550 is equipped with Garrett's exclusive

Belltone Coin Alert

™

that produces a distinctive

ringing tone when a target of high conductivity,

usually a coin, is discovered.
