Mocroprocessor Assisted ID makes undwanted  iron trash a thing of the past without loosing sensitivity or depth.  GMT has three ways to help identify iron trash.

AUDIO IRON GRUNT. No question about it, if it grunts - its iron!

BAR GRAPH that expresses a percentage of iron probability.

TARGET ANALYSER that collects data and feeds it to the audio and visual iron ID.  No depth loss - you hear all the targets.
