Long-Range Detection Systems (Automatic & Manual)

Ionic Long-Range System

3D Ground Imaging System
3D scan systems in metal detectors represent a significant advancement in detection technology, offering detailed imaging and more accurate identification of metal objects. By utilizing high-powered signals from four primary scanning sensors, this system can scan ground layers to generate three-dimensional images of detected objects at depths of 30 meters. This technology aids in comprehensively understanding the shape, size, and position of various objects, including metals, voids, treasures, underground utilities, and graves.
Live Scan System
Live scan systems in metal detectors provide live imaging and analysis, enhancing the detection process by offering immediate feedback on the location and type of buried objects such as metals, voids, and caves. Provides precise and up-to-date information whether you are looking for metals or voids, User-friendly interfaces and live data make these systems accessible and easy to use. Upgrade to the next generation of metal detection with our Live Scan Systems and unlock the secrets beneath your feet with confidence and ease.
Green: Soil nature
Red: Metals
Blue: Voids & Caves
Gradiosmart System
Designed for unparalleled deep scanning and precision, this system is meticulously designed to double-confirm the existence of specific targets, reaching depths of up to 10 meters. By relying on the magnetic fields created around metals over the years, our Gradio smart System excels at detecting both large and small objects including metals and voids. Whether you're searching for buried treasures or underground utilities, our Gradio smart System ensures no detail goes unnoticed.
Geophysical System
Geophysical systems use advanced methods to accurately locate groundwater sources or detect buried metals. By placing two ground probes in the soil and connecting them via cables to the device, the system scans the area and provides the percentage of probability of finding water or metal. This technology measures the soil resistance, allowing you to identify the type of target at depths of 500 meters if the target is water and 50 meters if the target is metal.
Pulse Induction System
The device detects buried metals using the pulse induction system by generating successive and strong current pulses emitted through the coil connected to the device, creating a magnetic field that quickly reflects when it passes through the target, causing a sharp electrical difference. This results in reflected pulses emitted by the metal target within the field such as gold, coins, bracelets and other metal targets. This system is easy to use and also allows the coil to be changed to detect small and large targets as it can reach a depth of up to 8 meters.
Spectrum Analyzer System
After determining the target location, the advanced spectrum analyzer system provides a two-dimensional scan of the target, working on the principle of sending successive and rapid pulses over the target location to determine its type and depth, giving you a clear and detailed view of the target. This system can be used by connecting 3 different coils to provide access to greater depths that may reach 8 meters.

I've been using the Ajax Primero for a couple of weeks now, and it's definitely one of the most advanced detectors I've tried. The 3D scanning and multiple detection systems are really impressive, it picks up targets at serious depth and gives you a lot of detail.
That said, it does take some time to get comfortable with all the features. The interface isn't hard to use, but there's a learning curve if you're used to simpler detectors. Once you figure it out though, it's incredibly powerful and accurate. Definitely recommended for experienced users or anyone ready to level up their gear.
Just started using the Ajax Primero and I have to say this thing is on another level. The build quality is excellent, and the amount of tech packed into this unit is seriously impressive. The multi-system modes and 3D ground scanning are super helpful for identifying different types of targets, and the depth it can reach is wild.
It took me a bit to learn all the features, but once I got the hang of it, I was finding things that my older detector completely missed. If you're serious about gold or treasure hunting, this is a fantastic investment. It's powerful, professional, and worth the money.
