Large-Format Digital Radiography System

Cuattro Max, supplied by J3Seven, is a large-format digital radiography system built specifically for explosive ordnance disposal (EOD) and bomb response teams. Its 17 × 34-inch wireless detector delivers wide field-of-view imaging so operators can capture more of a suspect device, vehicle panel or container in a single exposure while staying behind cover.

Designed in collaboration with bomb technicians, Cuattro Max combines rugged hardware, automatic exposure detection and advanced image processing with long-range wireless control. Features such as True OnePulse automatic exposure, minimal electromagnetic emissions and offline image capture help teams obtain high-quality X-ray images quickly and repeatably, even in challenging, cluttered environments.

Why Teams Choose Cuattro Max

Built with bomb techs, for bomb techs: Cuattro Max was developed specifically for EOD and bomb squad missions, with controls, workflows and image tools aligned to how operators actually work on scene.

See more in each shot: The large 17 × 34-inch (approx. 430 × 860 mm) detector gives broad coverage, and a modular form factor lets teams extend imaging length towards 51 inches (about 1.3 m) for long or irregular objects.

Automatic exposure with minimal EMI: Proprietary automatic exposure detection with True OnePulse and a zero‑EMI optical trigger is designed to reduce electromagnetic emissions around sensitive devices while still delivering strong signal and low noise.

Exposure Anytime capability: Operators can power on the detector and take an exposure even without a connected tablet or laptop, storing images on board and automatically pushing them to the acquire device when it becomes available.

Long-range, secure wireless control: Cuattro Max supports long-range wireless control of the generator and detector with fast image transfer. When paired with DTC’s SafeSignal™ technology, the system enables secure, low-latency imaging from stand-off distances beyond 0.5 miles (around 800 m), even in complex RF environments.

High-fidelity images at low dose: A 16‑bit dynamic range, high‑sensitivity imaging mode and multi-frequency image tuning algorithms help reveal fine detail in dense or cluttered devices while supporting low-dose techniques.

Ready for modern EOD workflows: Cuattro Max software integrates with XTK, supports common 5‑pin and 7‑pin sources and offers multi-detector capability with a streamlined “set and shoot” workflow so teams can concentrate on the target rather than the interface.

Frequently Asked Questions

What missions is Cuattro Max designed for?
Cuattro Max is built for EOD and bomb squad operations where large-format imaging and safe standoff distances are critical. Typical use cases include suspicious packages, vehicle-borne threats, infrastructure checks and other scenarios where teams need to see inside objects quickly without approaching the device.

How does the long-range wireless capability help?
Cuattro Max supports long-range wireless control of the detector and X-ray source with rapid image transfer. When configured with SafeSignal, the system offers secure, low-latency communications designed for contested RF environments and can operate from stand-off distances beyond 0.5 miles (around 800 m), helping reduce cable runs and time spent forward.

What kind of image quality can we expect?
The 17 × 34‑inch detector delivers 16‑bit images with a 140‑micron pixel pitch and high-sensitivity imaging modes, allowing operators to visualise dense or cluttered objects while using low-dose techniques. Multi-frequency image tuning tools help bring out fine details relevant to EOD decision-making.

Is Cuattro Max compatible with our existing EOD tools?
Cuattro Max software is designed to integrate with XTK, a common exploitation tool in EOD communities, and supports a range of 5‑pin and 7‑pin X-ray sources. This allows many teams to bring Cuattro Max into existing toolchains with minimal change to their standard operating procedures.

What support does J3Seven provide?
J3Seven works with Defence, law enforcement and specialist response units across Australia and New Zealand. We can help specify a Cuattro Max configuration (including wireless options and generators), support integration into current tactics and training, and provide through-life support for hardware and software.
