Minelab PRO-SONIC Wireless Audio System for GPX, SDC, and X-TERRA Detectors

The Minelab PRO-SONIC is a wireless audio system that transmits detector signals to a receiver module with a built-in loudspeaker and headphone socket, using 2.4 GHz frequency-hopping technology to achieve clear sound with minimal time delay. GPX 5000, GPX 4500, SDC 2300, E-TRAC, Safari, and X-TERRA series owners who hunt in areas where cable management is a nuisance, rocky terrain, dense brush, or long sessions where a wired connection restricts movement, gain freedom without sacrificing audio clarity. The PRO-SONIC system includes both transmit and receive modules, a universal charger, an SDC 2300 adapter cable, and a dual charging cable, so you can run it with any compatible Minelab detector out of the box.

What's Included with the PRO-SONIC Wireless Audio System

• PRO-SONIC Receive Module with internal loudspeaker, 6.35mm (¼-inch) headphone socket, and metal belt clip
• PRO-SONIC Transmit Module with audio cable (6.35mm/¼-inch connector)
• Universal Charger (AC and car charger)
• SDC 2300 adapter cable
• Dual Charging Cable (1 × USB-A, 2 × USB Micro-B)
• Getting Started Guide

Why GPX, SDC, and X-TERRA Owners Reach for the PRO-SONIC

• Wireless freedom in rough terrain: the 10-meter operating range lets you mount the receiver on a harness or belt and swing without cable snags on rocks, branches, or equipment.
• Built-in speaker or headphone flexibility: run audio through the receiver's internal loudspeaker when you want ambient awareness, or plug in your own metal detector headphones – wireless & wired for every machine when you need isolation in noisy environments.
• SDC 2300 compatibility out of the box: the included adapter cable connects the transmit module to the SDC 2300's unique audio output, so you don't need to source a third-party cable.
• Frequency-hopping interference rejection: the system establishes a piconet communication network using the 2.402–2.480 GHz ISM band, hopping frequencies to eliminate crosstalk from other wireless devices in crowded parks or group hunts.
• Charge anywhere: the universal charger works with AC power, car outlets, or USB sources, and the dual charging cable lets you top up both modules simultaneously between sessions.

Receiver-Module Belt Clip and Volume Control for All-Day Hunts

The PRO-SONIC Receive Module mounts to a harness strap or belt using a metal clip, keeping the unit secure during long swings and reducing the risk of drops when you kneel to dig. The adjustable volume setting lets you dial in the right level for your environment, louder in wind or near traffic, quieter when you're working a quiet site and want to preserve hearing. The 6.35mm headphone socket accepts standard ¼-inch jacks, so you can swap between different headphones without needing adapters. Our team has run the PRO-SONIC on multi-hour gold prospecting sessions with Minelab metal detectors & gold prospecting equipment, and the receiver's internal speaker has proven useful for quick surface scans where you don't want to don headphones but still need reliable target audio.
