Garrett 1/4″ Headphone Adapter for AT Pro, Infinium, Sea Hunter & ATX

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