Description
Underground Magnetics Mag 9 is the latest and advanced guidance for the Horizontal Directional Drilling industry in the wireless segment. It uses a special 15″ Tx that combines Sub-K and high frequencies. This helps drill under reinforced concrete surfaces. It also allows for switching downhole while drilling in both RCC and regular soil conditions.
The tool can reach depths of up to 110 meters. It features a screen that displays the prediction depth. It also has downhole power backup for up to 120 hours. This is possible with rechargeable lithium batteries.
This capability is excellent for longer and deeper bores, pipelines, and rock drilling. It can log the bore on the touch screen display and provide a real-time logging view.
Engineers design the Mag 9 Frequency Locator System for professionals who demand accuracy, reliability, and durability in every survey or utility-tracing application. It has 16 selectable frequencies from 0.325 kHz to 41 kHz. This offers clear signals and flexibility for accurate underground detection.
This locator can reach distances of up to 3,000 feet. It uses four radio channels with telemetry. This ensures clear communication, even in challenging terrains.
The Mag 9 runs on a 12.5V rechargeable lithium battery. It can last up to 50 hours of continuous use. This makes it great for all-day performance in the field.

The new Mag 9 system now offers an even easier interface, delivering exceptional power and versatility. The standard Echo 50x transmitter works with the Mag 9.
It allows sub-kHz frequencies. This gives excellent performance at depths of up to 30 feet in .325.
The system operates at kHz, reducing interference from rebar and wire mesh. It can quickly switch to high frequencies up to 41 kHz. This allows for depth and distance measurements of up to 150 feet.
Add to that, Mag 9 drill display with 7” color touch screen, built-in Data-Log system, and the best bang for the buck in the industry.
The Underground Magnetics Mag 9 receiver marks a significant step forward for walkover HDD locating solutions. The latest edition of our Mag Series offers the deepest depth and widest range in the industry.
It also offers great precision and accuracy. By combining our strong engineering skills with user-focused design, the Mag 9 delivers exceptional power and performance. It is also priced lower than similar products that offer fewer features.
Locator

Underground Magnetics Mag 9 is the latest in the series with advanced locating features and stoutly built. It has a Dual 3D Faraday Shield antenna.
The screen is bigger at 4.5 inches. It shows extra drilling information. It works with transmitters that have a depth range of up to 110 meters under standard test conditions.
Display

The 7″ color LCD monitor is easy to read in any condition. The touchscreen technology provides an intuitive user interface. Built-in data-logging features let users automatically track and record bore data and profiles. This helps measure, document, analyze, and validate conditions.
Four radio channels provide telemetry. The range is up to 500 meters with our standard antenna. It can reach up to 1,800 meters with an extended-range antenna. A rechargeable 12.5V Lithium battery provides up to 50 hours of use before needing to be recharged.
