# Operation in a Pool Pools are acoustically quite different when compared to natural aquatic environments and are often difficult for sonar devices, including the ROV Locator. Most pools are very sonically reflective, the reflections are usually very specular, and the reflective surfaces are many and are close to the sonar device. These reflections turn the pool into a morass of interference patterns. Generally, ROV Locator performance in a pool is not predictive of performance in natural environments. If you try to operate an ROV Locator system in a pool, you can expect erratic connections and large errors in estimates of bearing, elevations, and slant range. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.ceruleansonar.com/c/rov-locator/fundamentals-useful-to-system-designers/operation-in-a-pool.md?ask= ``` The question should be specific, self-contained, and written in natural language. 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.
