1/4" Headphone Adapter
¼” Headphone Adaptor by Garrett
Allows land-use headphones with a ¼” male jack to be used with the Garrett ATX, 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.
