Important: The Titan X13's 60-meter figure and Primero MD15's 70-meter figure should not be interpreted as equivalent, independently demonstrated metal detection depths. The technologies, targets, and operating conditions associated with each claim must be considered.
2. Search Systems: 11 vs. 15 Technologies
One of the most noticeable differences between the Titan X13 and Primero MD15 is the number of advertised search systems.
However, the number alone does not determine detection performance.
A more useful comparison is understanding what each system does and how it contributes to the exploration process.
GER Titan X13: 11 Search Systems
The Titan X13 combines 11 search modes organized into five technology groups.
EMF Detection Systems
- Direct EMF detection
- 3D imaging using EMF technology
Pulse Induction Systems
- General PI metal detection
- Direct PI target analysis
Magnetometer Systems
- Magnetic void and cavity investigation
- Magnetic metal detection
Ionic Detection
- Ionic search for ancient buried treasures
Long-Range Detection
- Gold and precious metals
- Diamonds
- Gemstones
- Custom long-range search
The Titan X13's biggest distinction is its combination of electromagnetic detection, dedicated PI modes, magnetic investigation, and long-range exploration.
For buyers interested in using different sensing principles during a search, this combination is worth examining.
Ajax Primero MD15: 15 Search Systems
The Primero MD15 includes 15 manufacturer-described systems:
- Automatic Long-Range Detection
- Manual Long-Range Detection
- Ionic Long-Range Detection
- Gradio Smart
- Live Scan
- Ground Sonar
- Ground Imaging
- Graph System
- Discrimination System
- Pinpointer
- Quick Scan
- Spectrum Analyzer
- Automatic Geophysical System
- Manual Geophysical System
- Imaging Geophysical System
Ajax organizes these capabilities into four broader platforms: long-range exploration, ground imaging, electromagnetic signal analysis, and geophysical investigation.
Its main distinction is the inclusion of several systems intended to examine subsurface conditions and groundwater in addition to metallic targets.
Which Has Better Search Technology?
The Titan X13 offers a more clearly defined combination of dedicated PI, EMF, magnetometer, ionic, and long-range modes.
The Primero MD15 offers a wider range of operating functions, particularly for imaging, target analysis, and geophysical investigation.
The key difference is not simply 11 versus 15 systems. It is which technologies are useful for your specific search objective.
3. Long-Range Detection: Titan X13 vs. Primero MD15
Both manufacturers advertise long-range exploration capabilities.
GER Detect lists a maximum forward search distance of up to 3,000 meters for the Titan X13.
Ajax Detection also advertises up to 3,000 meters for the Primero MD15's automatic and manual long-range systems.
On paper, neither detector has an advantage in maximum advertised horizontal range.
However, their operating options differ.
Titan X13 Long-Range Systems
The Titan X13 includes dedicated search modes for gold, precious metals, diamonds, gemstones, and custom targets.
GER Detect describes these systems as intended to help users explore large areas and investigate potential target locations.
Primero MD15 Long-Range Systems
The Primero MD15 offers automatic and manual long-range modes.
The automatic mode is designed for users who prefer a simplified search process.
The manual mode allows operators to select parameters such as target category, search distance, and depth settings.
Ajax also includes a separate ionic long-range mode, advertised with a maximum range of 200 meters.
Which Is Better for Large Areas?
Both devices are marketed for large-area exploration.
The Primero MD15 offers separate automatic and manual operating approaches, while the Titan X13 organizes its long-range functions around different target categories.
However, long-range precious-metal detection is scientifically controversial. Extraordinary claims concerning distant gold identification should be evaluated through controlled, independently verified testing.
A long-range indication should be treated as a potential lead requiring investigation—not confirmation that gold is present.
4. Detection Depth: 60 Meters vs. 70 Meters
Depth is one of the most frequently discussed specifications when comparing professional gold detectors.
GER Detect advertises a maximum depth of 60 meters for the Titan X13.
Ajax Detection advertises a maximum depth of 70 meters for the Primero MD15.
Does this mean the Primero MD15 detects gold 10 meters deeper?
Not necessarily.
These figures describe manufacturer-advertised maximum capabilities rather than standardized, directly comparable tests.
Why Maximum Depth Can Be Misleading
Actual metal detection performance depends on several factors:
Target Size + Target Composition + Detector Technology + Sensor or Coil + Soil Mineralization + Target Orientation + Ground Conditions + Operator Technique
For example, detecting a large buried metallic container is fundamentally different from detecting a small natural gold nugget.
A system capable of identifying a large subsurface anomaly should not automatically be expected to detect a small gold coin at the same depth.
Primero MD15 Has Different Depth Specifications for Different Systems
Ajax provides separate advertised figures for several operating modes:
| Primero MD15 System | Manufacturer-Advertised Maximum Depth |
|---|---|
| Automatic long-range | 70 m |
| Manual long-range | 70 m |
| Ionic long-range | 20 m |
| Ground imaging | 30 m |
| Gradio Smart | 10 m |
These numbers illustrate why it is important to identify the actual search technology behind a depth claim.
For the Titan X13, the overall 60-meter specification should not automatically be applied to each individual PI, EMF, or magnetometer mode.
Our recommendation: Never choose a professional gold detector solely because one manufacturer's advertised maximum depth is greater.
Ask what target was used, how the result was obtained, and whether the claim has been independently verified.
5. 3D Ground Imaging: Which Detector Offers Better Underground Visualization?

Both detectors include manufacturer-described underground imaging capabilities, but their approaches differ.
Titan X13: 3D Imaging Using EMF Technology
The Titan X13 includes a dedicated 3D imaging mode based on EMF technology.
GER Detect describes this system as a method for investigating underground targets and presenting results through the device's interface.
This feature complements its direct EMF detection system.
The Titan X13 also includes separate magnetometer systems intended for investigating metallic targets and voids.
Primero MD15: Ground Imaging With Dedicated Software
The Primero MD15 includes a Ground Imaging system using four high-sensitivity sensors, according to Ajax.
The manufacturer advertises a maximum imaging depth of 30 meters.
One of its distinguishing features is the ability to review scanning information on the detector or through an included tablet running Primero MD software.
The software is designed to display graphical information about suspected underground targets, including estimated shape, size, and depth.
Which Is Better for 3D Scanning?
The Primero MD15 has a clearer published advantage in its dedicated tablet-based imaging and analysis workflow.
The Titan X13 offers EMF-based 3D imaging integrated with its other detection modes.
However, the available manufacturer specifications do not establish which produces more accurate underground images.
Can Either Detector Actually See Gold Underground?
No 3D scanner should be treated as an underground camera.
Graphical representations are interpretations of sensor measurements.
A red area, metallic classification, or three-dimensional shape does not independently confirm that the target is gold.
Repeated measurements and appropriate verification remain essential.
6. Pulse Induction: An Important Difference for Metal Detection
Pulse Induction is an established electromagnetic metal detection technology.
A PI detector transmits electrical pulses through a coil and analyzes the resulting electromagnetic response.
Depending on its design, PI technology can be particularly useful in mineralized environments and for detecting metallic targets.
Titan X13 Pulse Induction Systems
The Titan X13 includes two dedicated PI modes:
General Pulse Induction Search: Intended for searching for buried metallic objects.
Direct Pulse Induction Analysis: Designed for additional target investigation.
These dedicated PI modes are among the Titan X13's most important published features.
Primero MD15 Coil-Based Detection
The Primero MD15 includes coil-based systems such as Quick Scan, Discrimination, Pinpointer, and Spectrum Analyzer.
Ajax describes the Spectrum Analyzer as using successive pulses to investigate a target.
However, its current MD15 documentation does not present a separately named conventional PI mode in the same way as the Titan X13.
This distinction matters because buyers should compare the actual coil specifications, operating principles, and field performance rather than assume all pulse-based systems behave identically.
Which Is Better for Direct Metal Detection?
The Titan X13 has the clearer published advantage for buyers specifically seeking dedicated Pulse Induction operating modes.
The Primero MD15 offers several coil-based detection and analysis functions, but their practical performance should be evaluated through demonstrations using comparable targets and soil conditions.
7. Magnetometer vs. Gradio Smart: Investigating Underground Anomalies
Both detectors include systems intended to investigate magnetic or related subsurface responses.
Titan X13 Magnetometer Systems
The Titan X13 includes two dedicated magnetometer modes:
- Magnetic metal detection
- Magnetic investigation of cavities and voids
Magnetometers measure variations in magnetic fields.
They can be useful for investigating ferrous objects and magnetic geological features.
However, gold itself is not ferromagnetic.
A magnetic anomaly does not automatically mean gold is present.
Primero MD15 Gradio Smart
Ajax describes Gradio Smart as a system for investigating metallic targets and underground voids.
The manufacturer advertises a maximum depth of 10 meters for this mode.
The Primero MD15 also includes other scanning and imaging functions that may be used during subsurface investigation.
Which Is Better?
The Titan X13 offers two clearly separated magnetometer functions.
The Primero MD15 integrates Gradio Smart into a broader imaging and analysis platform.
Neither manufacturer's descriptions provide sufficient independent evidence to conclude that one system identifies underground gold more accurately.
8. Groundwater Detection: A Major Advantage of Primero MD15
One of the most important differences between these detectors is groundwater exploration.
The Primero MD15 includes three dedicated geophysical systems:
Automatic Geophysical System
Ajax describes this mode as using differences in electrical resistivity to investigate subsurface conditions.
Manual Geophysical System
This mode uses electrodes and allows more direct operator control over measurement settings.
Imaging Geophysical System
Ajax markets this system for groundwater investigation and visualization.
These functions expand the Primero MD15 beyond conventional gold and treasure exploration.
The Titan X13 does not list equivalent dedicated electrical-resistivity groundwater investigation modes in its published specifications.
Which Is Better for Groundwater Exploration?
The Primero MD15 is the more appropriate choice based on the manufacturers' listed features.
However, locating groundwater, estimating aquifer properties, and selecting a productive drilling location are complex geophysical tasks.
Electrical resistivity measurements can help investigate subsurface conditions, but they do not guarantee that a particular location will produce usable groundwater.
Professional hydrogeological assessment and drilling verification may still be necessary.
9. Which Detector Is Better for Gold Nuggets?

This is an important question for customers interested in natural gold prospecting.
Both the Titan X13 and Primero MD15 are marketed for gold exploration, but small gold nuggets present a very different challenge from larger buried treasure.
Detecting tiny nuggets requires sensitivity to small metallic targets and suitable ground handling.
The Titan X13 includes dedicated PI modes, which may make it particularly interesting to buyers seeking electromagnetic metal detection capabilities.
The Primero MD15 includes coil-based detection and analysis systems that may also be relevant to metallic target searches.
However, neither manufacturer's advertised long-range depth specifications establish performance on subgram gold nuggets.
Small Gold vs. Deep Treasure
Consider three different objectives:
Small natural nuggets: A specialized VLF or gold-focused PI detector may be more appropriate.
Larger buried metallic objects: Detector technology, coil configuration, target size, and ground conditions become important.
Underground anomalies or possible chambers: Imaging and appropriate geophysical methods may provide useful additional information.
For serious natural gold prospecting, buyers should request demonstrations using actual gold nuggets of realistic sizes.
10. Which Is Better for Cavities, Tunnels, and Buried Chambers?
Both detectors are marketed for investigating underground cavities and structures.
The Titan X13 includes dedicated magnetometer modes and EMF imaging.
The Primero MD15 offers Ground Imaging, Ground Sonar, Live Scan, and Gradio Smart.
Titan X13 for Underground Structures
The Titan X13's magnetic and imaging modes are intended to help investigate underground anomalies, including possible voids.
Primero MD15 for Underground Structures
The Primero MD15 offers several methods for investigating a defined location.
Its Ground Sonar system is marketed for investigating density variations and potential underground structures.
Its Ground Imaging system provides additional visualization options through dedicated software.
Which Is Better for Cavity Investigation?
The Primero MD15 offers a broader published selection of scanning and visualization functions.
The Titan X13 offers a combination of magnetometer and EMF-based investigation.
For professional cavity mapping, however, neither device should automatically replace established geophysical survey methods.
Depending on the site, ground-penetrating radar, electrical resistivity tomography, or other appropriate geophysical methods may be better suited to investigating subsurface structures.
11. Soil Mineralization and Difficult Ground Conditions
Gold exploration frequently takes place in challenging environments.
Common ground conditions include iron-rich soil, magnetite, black sand, hot rocks, clay, salts, and volcanic minerals.
These materials can complicate electromagnetic detection and subsurface measurements.
Titan X13
The Titan X13 includes multiple detection technologies, including dedicated PI modes.
PI technology can offer advantages in certain mineralized environments, depending on the detector's actual design and settings.
Primero MD15
Ajax describes automatic and manual ground calibration features for the Primero MD15.
The manufacturer markets the system for operation across different soil types, including mineralized and complex ground.
Which Handles Mineralization Better?
There is insufficient independent comparative field data to declare a winner.
The answer depends on the specific operating mode, target, soil conditions, and measurement method.
For buyers working in heavily mineralized goldfields, repeatable field performance should carry more weight than general claims about immunity to difficult ground.
12. Ease of Use, Display, and Data Analysis
The Titan X13 and Primero MD15 also differ in how operators interact with their systems.
Titan X13
The Titan X13 provides an integrated interface for its detection modes.
Its published specifications include six supported languages.
The device is designed around selecting a particular technology for the investigation being performed.
Primero MD15
The Primero MD15 includes a 5-inch TFT color display.
Ajax also provides Primero MD software for reviewing ground-imaging information on an included tablet.
Other published features include eight interface languages, configurable notifications, and the ability to save scan data.
Which Is Easier to Use?
The Titan X13 may appeal to operators who prefer working directly with dedicated search modes.
The Primero MD15 may appeal to those who want additional visualization and software-based analysis.
However, more advanced features can introduce a steeper learning curve.
The most useful system is the one the operator can configure, interpret, and verify correctly.
13. Which Detector Is Better for Professional Treasure Hunting?
For professional treasure exploration, the best choice depends on the project.
Consider two scenarios.
Scenario A: Searching a Large Property for Buried Metallic Treasure
An operator has access to a large property with historical reports of buried metallic objects.
The search requires initial research, systematic area coverage, and direct investigation of promising locations.
In this situation, the Titan X13's combination of long-range modes, dedicated PI detection, EMF systems, and magnetometer functions may be appealing.
The Primero MD15 also offers long-range exploration, coil-based detection, and imaging capabilities.
Neither system's long-range claims should be relied upon without independent verification.
Scenario B: Investigating a Suspected Underground Chamber
An operator has identified a relatively small area where an underground chamber or buried structure may exist.
The project requires systematic measurements, graphical analysis, and potentially geophysical investigation.
Here, the Primero MD15's imaging software, Ground Sonar, and geophysical modes may provide a broader selection of investigation tools.
However, the appropriate instrument must still be selected according to the geology, expected structure, and required measurement accuracy.
