Iron Audio is the Garrett ACE 400's headline feature, and it vocalizes the iron portion of mixed targets as a low grunt while keeping high tones on conductive metals like coins and rings. With a small amount of iron discrimination set, the machine still reports iron in the audio, so we can call bottle caps before digging and confirm a clean coin signal is not a coin sitting on the edge of a rusted nail. We use Iron Audio in trashy parks and farm fields where junk iron masks good targets, and it cuts recovery time in half.
