GARRETT 1/4" Headphone Adapter
Allows land-use headphones with a 1/4” male jack to be used with the
Garrett ATX, AT Gold, AT Pro, Infinium and Sea Hunter models.
(Not intended for submerged use.)
OPERATION NOTES: Inserting the headphone plug into the connector will provide
sound from the headphones only and will automatically disable the detector's speaker.
This automatic speaker-disable feature requires the input impedance of the headphones
to be 10,000 ohms or less.
Note that some non-Garrett headphones may not meet this requirement and
will require the addition of a 10,000 ohm termination resistor inside the connector to disable the speaker.
