The Delta is a single-frequency detector that operates at 7.8 kHz. While having a preset ground balance setting, which eliminates any complicated ground balancing procedures, it offers surprising performance over a wide range of ground conditions. It has three separate motion-based search modes, one Discriminate and two All-Metal modes (shown as A1 and A2 on the display). It also has a non-motion all metal pinpoint mode to aid in zeroing in on detected targets.
