Iron Audio on the Garrett ACE Apex is a feature that helps correctly identify complex iron objects, such as bottle caps, that sometimes ring up in the non-ferrous VDI range. When Iron Audio is enabled, the detector plays both the iron grunt and the non-ferrous tone for mixed targets, so you hear the iron signature underneath a false high tone. This lets you make a more informed dig decision without automatically accepting every high tone as a keeper. Iron Volume is a related feature that lets you drop the volume of iron hits by up to eight adjustment steps without silencing them completely, so iron stays audible but quieter in trashy sites while non-ferrous tones remain at full volume.
