Navigating uncharted waters

ICS helped a major marine electronics manufacturer develop one of the industry’s most powerful sonar and navigation devices, providing Qt expertise and assisting the client’s in-house team to ensure the project stayed on track.

Touchscreen Sonar and Navigation Device for Anglers

A major marine electronics manufacturer was developing what it envisioned as the Touchscreen fishing device inside boatindustry’s most powerful sonar and navigation device for recreational and professional anglers worldwide. The sophisticated device would incorporate an intuitive interface and quick menus, as well as an integrated web browser, online PDF manual reader, tide and current charts, sun and moon data visualization, a timer/stopwatch, a fuel indicator, and integration to a third-party audio system. The product also would also allow users to seamlessly switch between physical keypad and touchscreen control, making it easy to target prey and navigate when conditions are dry or wet.

In the early stages of the project the company selected Qt on Yocto-embedded Linux for application development and started creating the user interface. With only limited Qt experience, they called Integrated Computer Solutions, Inc. (ICS) for assistance to ensure they would stay on track.


Our client had a talented and highly productive team of industrial designers who created beautiful designs for the user interface. In fact, they filled the pipeline with a huge number of screens and dialogs — too many for the company’s own developers to quickly implement. They needed a boost from experts with more Qt experience.


Initially, the client used older QWidget technology within Qt to create an iPhone-style touch user interface (UI). To accelerate development, ICS introduced them to QML and showed how fast a designer’s mockup could be transformed into an identical-looking, working UI. Though initially somewhat hesitant to embrace the newer QML technology, the client agreed to let ICS develop most of the remaining UI in QML while keeping the existing QWidget code. This arrangement supported speedy development while freeing the client’s software team to focus on the backend.


Working in harmony, ICS and our client kept product development on track. Today, anglers worldwide rely on the market-leading device for their fishing and navigation needs.
