The Minelab Pro-Sonic is a popular wireless audio system designed to enhance the metal detecting experience. It is compatible with most metal detectors and is known for its excellent performance and stability. In this article, we will take a closer look at the pros and cons of using the Pro-Sonic, diving into key features such as waterproofing, sensitivity, backpack convenience, small size, ease of use, mineralised soil compatibility, volume control, and the headphone socket.


1. Super Easy to Use

The Minelab Pro-Sonic is very easy to use. There may be a slight learning curve for users who are new to wireless audio systems, but they will quickly become familiarised with the unit.

2. Backpack Convenience

The Pro-Sonic is a backpack-friendly system, as it is lightweight and compact and come with an large clip making it easy to attach to most harnesses or backpacks that have attachments points such as “D” rings. The transmitter module which is plugged into the metal detector is small and can be easily fastened to the detector with some Velcro if required.

3. Small Size

The small size of the Pro-Sonic modules is another advantage. The compact design allows for easy transportation and storage, without adding unnecessary bulk to the user’s metal detecting setup.

4. Built-In Volume Adjustment

The Pro-Sonic offers a simple one-button volume adjustment technique. I quick press on the volume button, increases the volume by one step, a long press reduces the volume.. This feature is particularly useful when detecting around other users or when being used at popular locations. 

5. Compatibility with almost all detectors

The Pro-Sonic is also compatible with most metal detectors, making it a versatile choice for both novice and experienced detectorists.

6. Responsiveness

The Pro-Sonic works well and is very responsive to signals, not like some bluetooth connectors which can be very laggy in relating a signal to the headphones, making it harder to accurately pinpoint a signal.

7. Headphone Socket

The Pro-Sonic receiver module includes a standard 6.5mm (1/4-inch) headphone socket , enabling users to connect their preferred headphones for a more private and immersive detecting experience. This feature is especially beneficial for those who want to minimise environmental noise or avoid disturbing others while detecting.


1. Price

One potential downside of the Pro-Sonic is its price. The system is relatively expensive compared to some other bluetooth audio systems on the market. While the Pro-Sonic offers numerous benefits, some users may find the cost prohibitive, particularly if they are new to metal detecting or have a limited budget.

2. Potential for Interference

Despite its sensitivity adjustment feature, the Pro-Sonic is still susceptible to interference from other electronic devices or environmental factors. While the system is designed to minimise these issues, some users may still experience occasional audio disruptions or signal loss.

3. Non-Waterproof Design

One of the most significant disadvantages of the Pro-Sonic is its waterproof design. The transmitter and receiver modules are not waterproof and should not be used near water at all. This is lack of water proofing makes the Pro Sonic completely unsuitable for use in and around creeks and rivers as there is always the chance of these units getting wet!

The Minelab Pro-Sonic is a powerful and versatile wireless audio system that offers numerous benefits for metal operators. Its waterproof design, sensitivity adjustment, backpack convenience, small size, ease of use, mineralised soil compatibility, volume control, and headphone socket make it an attractive choice for many users. However, potential drawbacks, such as the price, compatibility issues, battery life, potential for interference, and learning curve, should be considered before making a purchase.

Overall, the Minelab Pro-Sonic is an excellent addition to any metal detecting setup, providing users with enhanced audio performance and convenience. By carefully weighing the pros and cons, detectorists can determine if the Pro-Sonic is the right choice for their needs and preferences.
