SMS Text Message and Email notifications can alert you of any adverse conditions including low-power, reports, power profile and schedule recommendations, damage to the system, and more.

Focus and amplify ultrasound up to 120W with INTELIBOOST™. Synchronous operation of transducer groups can deliver concentrated ultrasound for specialized applications.

Granular frequency control results in precision output that targets your unique application. Convenient presets compensate for hull materials, drive types, thrusters, and more.

An industry first – each transducer can be independently controlled for customized power delivery, frequency tuning, and schedule.

HDi systems offer genuine real-time continuous calibration, pulse-by-pulse, ensuring your systems delivers maximum effectiveness.

Want maximum power? It’s yours for the taking. Require extreme efficiency? We have your back. Easily adjustable presets will compensate for solar, wind, and limited power availability.

Fine-grained control allows you to adjust power delivery for each individual transducer. Adjust ranges, maximums, dynamic ranges based on battery voltage, time and day schedules, and more.

Let’s face it – space for mounting new hardware is probably limited on your boat. Adjustable mounting hardware ensure the perfect fit.

AccordionNeed to deactivate a transducer? No problem. Easily activate and deactivate individual transducers on the fly, remotely.

Not so savvy with electronics? Rest easy – every HDi system is factory preset to operate fully-automatically. Simply take it out of the box and plug it in.

Access your HDi hardware with a direct connection from your phone – no internet required. A direct connection can be made to the device through Bluetooth or WiFi.

You’re never too far away. Maintain complete control of your HDi system from anywhere. Access all settings, controls, diagnostics, and reports.

Engineered for a lifetime. HDi systems are designed for easy care and maintenance – modular architecture ensures any adverse damage will not interfere with system operation and is easily replaced.

Looking for that perfect setting and need to track your changes? HDi provides a complete diagnostic history of runtime, power consumption, events, changes, alerts, and more.

Adverse conditions in your boat’s electrical system can cause electronics to freeze-up. Don’t worry, your HDi can detect power supply issues and take corrective action.

Dedicated LED indicators for each transducer provide visual feedback of the status of your system – no app, no guessing, no problem.

Each HDi controller is equipped with an internal speaker that can immediately alert you in the case of a power supply issue or fault.

Whether Lead-acid, AGM, Lithium-ion, or LiFePO4, rest easy knowing that your HDi system will provide the right power profiles and conditioning for your specific battery chemistry.

Unlike other electronic devices on your boat, Hull Shield HDi systems actively monitor battery type and voltages, actively implementing procedures to preserve and protect the health of your battery.

Your HDi system will modify and adapt its power consumption based on changing conditions. If your battery levels are depleting, the circuitry will automatically adapt to conserve power and battery health.

HDi systems are protected from reversed power and grounding situations occurring in your battery system or during installation.

Accidents happen. If a wire is damaged or severed, your HDi system will detect, isolate, and promptly alert you of the issue.

Active fault protection can seamlessly detect and isolate faults while mitigating downtime caused by adverse conditions.

HDi transducers are completely submersible, waterproof, and 100% galvanically isolated.

Every boat is a wet environment. Feel secure in knowing that your HDi controller is protected against water intrusion.

Your investment is always protected. Individual internally fused modular components ensure complete circuit protection and redundant operation.

Power systems in boats can be noisy and damaging to sensitive electronics. HDi systems integrate a robust power-filtering to ensure long-term and reliable operation.

In the world of ultrasonic antifouling, digital current control results in efficiency and fine-control. Hull Shield pioneered this technology, establishing it as an industry standard. Proprietary architecture provides precision control and extended product lifespan.

Each ultrasonic pulse is digitally controlled to reduce transducer stress, ensuring silent operation and transducer longevity.

Whether installing a new system or moving it to a different vessel, the HDi system outshines the competition by providing the simplest, fastest, and most secure connections possible.
