Operating the Detector
Detect Modes
The X-Terra PRO offers three pre-programmed detect modes, each optimized for specific environments:
- Park Mode: Ideal for high-trash areas like parks, designed to filter out common modern junk and focus on valuable targets.
- Field Mode: Best for fine coins and artifacts in open fields, offering deeper penetration and sensitivity to smaller targets.
- Beach Mode: Specifically designed for sand and saltwater environments, compensating for mineralization to find treasures underwater up to 16 ft (5 m).

Audio Control and Target Identification
The detector provides clear audio tones to distinguish between different target types and estimate their size and depth. It is compatible with both wireless and wired headphones for enhanced audio clarity. The large LCD display provides visual feedback on target identification numbers, depth, and discrimination settings.
