How to Run a Fish Finder on a Aqua Compact PC

Traditionally, fish finders require dedicated hardware displays. With this new setup, your Aqua Compact PC becomes the display and control center.
The Aqua Compact PC is designed specifically for marine environments, offering reliable performance with low power consumption.
Here’s how it works:
- The DFF1-UHD+ sounder collects sonar data
- The data is sent via Ethernet to the Aqua Compact PC
- TimeZero software sounder integration processes and displays the data
- You view sonar, charts, and navigation—all on one screen
