Escape From Routine

Proportional Audio response and Tone Roll Audio features allow user to hear subtle changes in target’s response to better judge conductivity, size, shape, and depth.
AT PRO™ International 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.
Proportional Audio Feature
The AT Pro™ International 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.

The AT Pro™ International also includes three Standard audio modes, which provide a full-strength beep regardless of a target’s amplitude. Many detectorists prefer this simpler, binary (either on or off ) target response.
AT PRO™ International Additional Features
High-Res Iron Discrim
40 levels of iron discrimination provide the fine resolution needed to separate a good target from iron trash
Fast Track Ground Balance
Automatic feature that allows the user to quickly ground balance the detector in mineralized soil conditions.
Digital Target ID
Numeric identification scale from 0 to 99. Identifies a target metal’s conductivity.
Electronic Pinpointing
This non-motion All-Metal Mode function is used to precisely locate a detected target’s position.
