AT MAX™ Iron Audio

Hear the iron trash before you dig it!

Iron Audio allows you to hear discriminated iron (normally silenced) to avoid digging undesired flat iron targets such as bottle caps or washers.

NOTE: To use the Iron Audio feature, some degree of Iron Discrimination must be set. In this demonstration, the Iron Discrim setting is at 35. Without Iron Audio, both the bottle cap and silver coin sound like good targets. With the Iron Audio, the bottle cap response includes iron “grunts” to indicate this might be a trash target.
Automated Ground Balance Window™
This Garrett exclusive feature can simultaneously "spread" the ground balance setting to a range of values to reduce ground response in severely mineralized areas. Automatic and manually adjustable ground balance options also available.

Go wireless with Z-Lynk Speed!

Sync to Garrett’s MS-3 wireless headphones that are included with the AT MAX™.

Enjoy the treasure tones only you can hear.

Maximum Detection Depth

Enhanced electronics, a 13.6 kHz operating frequency, and eight Sensitivity/Depth adjustments allow you to detect targets deeper than other Garrett AT detectors.
Hunt Day and Night
The AT MAX™ includes a backlit display feature, allowing you to continue hunting in low-light conditions.

Click the “Iron Audio/Light” button on the unit to see it in action!
