Garrett 1/4" Headphone Adapter

Garrett 1/4" Headphone Adapter
PN: 1626000

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 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
