Hull Shield HDi2 – Controller Only

Only $499 after exchange refund!

The new Hull Shield® HDi Series delivers the most powerful ultrasonic antifouling system in it’s class. The HDi2 model provides intelligent control of a powerful 60W of acoustic power. Wireless connectivity and access via a mobile app provides precise control. With integrated INTELISENSE™ Remote Monitoring, you can be alerted by SMS and email in case of a power failure or other issue occurring on your vessel.

Limited-Time Upgrade Program – Hull Shield® is offering a special upgrade program for current HD Series customers who want to move up to the all-new 2026 HDi Series!  Eligible customers can exchange their existing HD1, HD2, HD4, or HD100 controller for the corresponding HDi1, HDi2, or HDi4 Intelligent Ultrasonic Antifouling System.

Please note: the power connector design has been upgraded, and mounting hole spacing has been slightly modified. Otherwise, upgrading from HD to HDi is largely plug-and-play, allowing you to reuse your existing transducers for a smooth, cost-effective transition to the new generation of Hull Shield technology.

You will receive a $150 refund once your current (used) HD2 controller exchange is returned and processed.
