10 Best Fisher Metal Detectors 2025 in the United States

The Fisher Labs XLT30D Liquid Leak Detector is designed primarily for detecting leaks rather than traditional metal detection. This product features a battery-powered operation, making it easy to use in various locations without worrying about power supply. Although it is lightweight at just 0.01 ounces, which enhances portability, the ergonomic design might not be as refined for extended usage periods.

When it comes to the essential specs for metal detection, this model’s operating frequency is tailored for leak detection, so those seeking traditional metal detecting functionalities might find it lacking. The Big Foot and Multi-Sensor features can be beneficial for specific tasks, yet they might not align perfectly with the requirements of traditional metal detector users.

For those looking for a reliable leak detection tool in industrial applications, this product could be an excellent fit. However, enthusiasts or professionals seeking a comprehensive metal detector might need to explore more specialized options that offer robust features such as discrimination, ground balance, and detailed depth indicators. While the Fisher Labs XLT30D can be handy for its intended purpose, it may not meet the expectations of users focused on traditional metal detection.

The Fisher Labs M9711 Metal Detector is designed primarily for locating valves and metal boxes, making it a practical choice for utility workers and hobbyists. One of its standout features is the automatic retune button, which helps maintain optimal sensitivity during use, coupled with a sensitivity selector for fine-tuning detection. With an operating frequency of 4.5kHz, it can effectively detect larger metallic objects, though it may struggle with smaller targets compared to detectors operating at higher frequencies.

The manual ground compensation feature is a plus for users who may encounter varying soil conditions, allowing for better performance in different environments. The 11” search coil provides a decent range, enabling efficient searching over larger areas. An added headphone jack is convenient for private listening, which is great in crowded or noisy locations.

In terms of ergonomics, the M9711 weighs 3.9lbs, which is relatively manageable for extended use, although some users might find it slightly cumbersome over long periods. The adjustable length from 38” to 50” caters well to users of different heights, making it more comfortable for a wider range of people. It has a few drawbacks. The reliance on 2 x 9V batteries may not be the most convenient option for all users, especially considering the battery life of 25 to 35 hours, which may necessitate regular replacements during longer outings. Additionally, while the 4.5kHz frequency is good for certain applications, it may not be versatile enough for users looking to detect a variety of small objects or coins.

The Fisher Labs M9711 is a reliable metal detector for specific tasks like locating valves and boxes, making it suitable for professionals in utilities. For hobbyists or treasure hunters seeking a more versatile device, considering a model with a higher frequency and longer battery life might be beneficial.

The Fisher Gold Bug 2 Metal Detector is a standout choice for both new and experienced prospectors seeking to find gold nuggets. Its high operating frequency of 71 kHz provides exceptional sensitivity, making it capable of detecting small and deeply buried gold even in challenging terrains like highly mineralized soils. This makes it an ideal tool for those serious about gold prospecting.

One of its major strengths is the versatile coil combination. With both a 6-inch and a 10-inch elliptical search coil, users can adapt their approach depending on the environment—whether they need precision in tight spots or broader coverage for deeper targets. Additionally, the waterproof coils with ESI shielding ensure stable performance, reducing interference in different hunting conditions.

The advanced ground balance features allow users to fine-tune the detector to suit various mineralization levels. This is especially beneficial in extreme environments, enhancing the device's effectiveness in locating targets. The iron discrimination mode is another strong point, helping to filter out unwanted ferrous trash while ensuring that valuable non-ferrous targets are highlighted. The Gold Bug 2 boasts a commendable battery life of up to 35 hours, which is excellent for prolonged use. The robust construction adds to its durability in outdoor settings, making it well-suited for dedicated prospectors, while its advanced features may require a bit of a learning curve for newcomers.
