The AT Pro underwater metal detector features advanced, proportional (Pro) audio modes, allowing users to detect subtle changes in a target’s response. This helps treasure hunters accurately judge a metal object’s size, shape, and depth. With faster recovery time and improved target separation, this feature enhances performance in areas with adjacent targets.

For beginners, the AT Pro also includes three Standard audio modes, delivering consistent, full-strength signals regardless of a target’s amplitude. These modes provide a user-friendly experience, allowing users to develop their skills at their own pace.

PRO MODE AUDIO 

Proportional Audio response and Tone Roll Audio features allow users to hear subtle changes in the target’s response to better judge conductivity, size, shape, and depth.
