PROPORTIONAL AUDIO FEATURE
The AT Gold features advanced, proportional (Pro) audio modes. This allows the user to hear subtle changes in a target’s response. Proportional audio also helps the user to better judge a target’s size, shape and depth and has the additional benefit of a much faster recovery time when detecting adjacent targets.
CONQUER ANY TERRAIN
Manual and Automatic ground balance features, plus exclusive Garrett Ground Balance Window — which allows the user to “spread” the ground balance setting to reduce response to subtle ground variations.
AT GOLD™ 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.
