About Cerulean Sonar

Our Story

Cerulean Sonar is a spin-out of Digi Labs, a Minnesota based new product incubator. The Digi Labs R&D shop was set up by Larry Lukis, retired Founder, CTO, and Chairman of ProtoLabs, the world’s fastest manufacturer of custom prototypes and on-demand production parts.

An avid boater and inveterate engineer, Larry has been interested in marine robotics for many years. Larry was an early investor in Blue Robotics, SeaTrac, and a number of other marine/robotics oriented companies.

Meanwhile, one of the first initiatives at the Digi Labs incubator was an acoustic positioning system for underwater vehicles. Other acoustic developments started in parallel, and one of these became the Blue Robotics Ping Echosounder and Altimeter, licensed by Cerulean to Blue Robotics.

The Cerulean Sonar team includes former senior engineers, now “retired,” from the Proto Labs startup and early growth (up to $100 million) days.

The Cerulean Sonar Mission

"To leverage the latest advances in micro electronics and digital signal processing to bring you sonar products that are Sensibly Priced! We are passionate about making ocean exploration more accessible, and we know that not everyone has the budget of the US Navy and the Big Oil companies. That’s why we do it."

Cerulean Sonar members meet with Peter Schubert from BlueLink at the second annual Blue Robotics Open House in 2019.
