Typical applications include fish finding, navigation, and scientific explorations. Several frequencies and beam configurations are available. Note that the Sailbouy coloring is for illustrative purposes. ![Sailbouy model Echo](https://sailbuoy.no/hubfs/Website%20assets/Illustrations/Sailbouy%20model%20Echo.png) ## The SB Echo is equipped with the following communication and data collectors: ![Echo](https://sailbuoy.no/hs-fs/hubfs/Website%20assets/Icons/Echo.png?width=150&height=150&name=Echo.png) ### Echo Sounders With various transducers for fish finding,  navigation, hydrographic surveys, and scientific explorations. ![Conductivity](https://sailbuoy.no/hs-fs/hubfs/Website%20assets/Icons/Conductivity.png?width=150&height=150&name=Conductivity.png) ### Conductivity And Temperature Sensors Together with temperature and depth information, a good estimate of the water conductivity or salinity may be determined by measuring the conductivity of water ![Oxygen](https://sailbuoy.no/hs-fs/hubfs/Website%20assets/Icons/Oxygen.png?width=150&height=150&name=Oxygen.png) ### Oxygen Sensor For measuring biological and chemical processes in aquatic environments and oceanographic studies. ## Key Features of All our Unmanned Surface Vessels SB Echo is one of Offshore Sensing’s several Sailbuoy (SB) models. The Sailbuoy has been field-tested and developed in challenging environments such as the Arctic and North Sea. See our missions [here](https://sailbuoy.no/missions/?hsLang=en).  **Key features of all the Sailbuoy models include:** - Autonomy - Data collection - Monitoring and Data link - Design and Implementation - Navigation and Control [Our USV models](https://sailbuoy.no/unmanned-surface-vessels?hsLang=en) ![Sailbuoy_develogic](https://sailbuoy.no/hs-fs/hubfs/Website%20assets/Blog%20images/Sailbuoy_develogic.webp?width=600&height=400&name=Sailbuoy_develogic.webp) ## Book a meeting to learn more about the SB Echo **You are welcome to book a meeting directly with our CEO, Max Hartvigsen.** If you have general questions or inquiries about Offshore Sensing, our products, or our technologies, please visit our [Contact page](https://sailbuoy.no/contact/?hsLang=en).   [![Offshore Sensing_original_logo_fixed](https://sailbuoy.no/hubfs/Logo%20and%20Icons/Offshore%20Sensing_original_logo_fixed.svg)](https://sailbuoy.no?hsLang=en) - [Book meeting](https://sailbuoy.no/contact) - [Build your Sailbuoy](https://sailbuoy.no/unmanned-surface-vessels) - [Explained by Offshore Sensing](https://sailbuoy.no/explained-by-offshore-sensing) - [Resources](https://sailbuoy.no/resources) Offshore Sensing AS Sandslimarken 31 5254 Sandsli, Norway   [Crowdworks Company Profile](https://app.crowdworks.it/companies/offshore-sensing/update) ©2026 Offshore Sensing AS.
