Operating since 2009, eSonar is a commercial company with a mission to improve access to marine and subsea environmental data by applying advanced knowledge and translating that knowledge into actions that benefit mariners.  Our products are used extensively by fisheries scientists and marine companies in the Canada, U.S.A. and internationally to provide advanced knowledge of vessel and deployed equipment operations. 


Our staff of sonar engineers and signal processing experts are involved in continuous R&D to add new capabilities and improve our product capabilities.  Key features of our designs include synthetic pressure housings that are RF transparent to facilitate parameter adjustment and data offload without requiring opening of the subsea enclosure and have been tested to 2000m submerged depth.  We specialize in battery operated and power managed designs with long deployed lifetime and work closely with Memorial University to advance our technological solutions.


Our lighting division works with major international marine lighting companies to design the next level solutions in data-enabled LED marine lighting.  Our lighting solutions turn your marine luminaires into data platforms that are connected and powered over Ethernet.  Having your lighting system connected by Ethernet creates a distributed network on the vessel, allowing high-speed data access wherever there is lighting.  Built-in sensors in the luminaire combine with the central Ethernet backbone to enhance command and control of your vessel.


We specialize in persistent, low-power, battery operated subsea equipment with a focus on underwater acoustic technology and we offer provide custom product development and software services to associated marine and subsea industries. In additional to design services, E-Sonar’s primary product lines comprise sonar and acoustic systems, data enabled marine LED lighting and integrated trawl management (net monitoring) systems that acoustically telemetry data back to the vessel from deployed equipment. 


Our engineers use the latest in microprocessor technology to bring cutting-edge power management to subsea instruments and we make long-life, persistent solutions that can sense and telemeter custom data back to a nearby vessel or platform by reliable acoustic methods. Our rugged design methodologies and power management that can reduce power demand to micro-watts yielding outstanding deployed lifetimes. Our low-level software and firmware capabilities include programmable logic, network processors and we specialize in Arm processor types.  Our high-level software capabilities include user interface, signal processing, instrument control, long term monitoring, data collection and storage, data display and bespoke visualization. We work with the fishing industry, shipboard marine industries, offshore oil and gas, aquaculture, and autonomous underwater vehicles. Our engineers, software specialists, technologists and technicians are eager to work with you to deliver your next commercial designs for subsea applications.




Chief Technology Officer

Gary has more than 25 years’ experience in the marine sector in the areas of electronics and acoustics, project management and electronic and mechanical design.


He has a solid record in the developing products and technology for international markets. Gary has operated his own consulting company M3 Sonar Inc. and was a founder and director of Rutter Inc.  More recently he served as Vice-President of PanGeo Subsea Inc.  Gary holds a bachelor’s degree in Electrical Engineering.


Chief Scientist

David holds a First-Class Honours Bachelor of Science Degree from the University of Reading in the UK.  He worked as a Design Engineer for Racal Ltd. on the remote control of high frequency radio transmitters and receivers and subsequently obtained his Ph.D. on sonar data telemetry at the University of Birmingham.


He worked on underwater navigation systems prior to starting his own sonar design and manufacturing company Marine Acoustics Ltd., where he worked on naval applications of sonar until exiting the company in 1997.  David has more than 40 years’ experience in the design and manufacture of underwater acoustic systems.


Board Member

Brian has over 30 years of experience in the electrical engineering field as a hardware/software developer and project manager.


He previously worked at NorthStar Technical as the vice president (R&D) in the development of marine electronics and underwater acoustics, and as lead engineer in the development of marine navigation systems.  He served as manager of Information Technology for a National Research Council laboratory, responsible for the development of a distributed data acquisition and processing systems.  


Board Member

Early in his career, Jim had extensive involvement with the commercial fishing industry in Newfoundland and subsequently graduated in technology at the Marine Institute of Memorial University.  He previously served as President of NorthStar Technical, and later Vice-President of Marport before becoming a shareholder in eSonar.  Jim has widespread sonar design and marketing expertise and has significant international experience in marine technology.



Chris studied economics at Memorial University and worked in advertising during that sectors’ change over from print to digital.  From his base in Toronto, he joined a startup that was later acquired by Google and integrated to significant success.  Chris continues to work at Google and joined the Board of Directors of eSonar in 2018 after investing in the company.
