Our reasoning for this recommendation: * If the device is mounted shallower than \~25 degrees below horizontal, then when the vessel rolls or heels, then the device may not be able to capture points in the nadir. * If the device is pointed down further than \~50 degrees below horizontal, the ultimate achievable swath width will be reduced. Shown here is the Omniscan 3D Upgrade Kit mounted to the hull of a Blue Robotics BlueBoat using a 3D printable mount and bushings located here:
{% hint style="warning" %} While the angle of the Omniscan 3D can be mostly be freely adjusted due to the IMU compensation, it does not support facing straight down like the Surveyor 240. If the device is allowed to point straight down, it will interpret that as suddenly being mounted pointing in the other direction (points on the starboard side would appear on the port side) {% endhint %} --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.ceruleansonar.com/c/omniscan3d/getting-started/device-mounting.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
