Garrett 1/4" Headphone Adapter
Allows land-use headphones with a 1/4À¢â ¬À€ male jack to be used with the Garrett ATX| ATX Deepseeker| 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 impedence 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.
