Garrett 1/4 headphone adapter.

1/4 headphone adapter.

• Allows land-use headphones with a 1/4” male jack to be used with the Garrett ATX, AT Max, AT Gold, AT Pro, 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.
