A grayscale side-scan sonar image of a lakebed showing an exposed watch, a fishing lure, and a rusted knife, with labels.

A realistic grayscale side-scan sonar image of a lakebed showing underwater objects. Include three wristwatches buried at varying depths under silt: one fully exposed on the surface with a bright oval shape and shadow, one partially buried with a fuzzy halo effect, and one deeply buried invisible under silt blending into the muddy bottom. Also show a faint metallic fishing lure and a rusted knife partly obscured by silt. Annotate the image with labels pointing to each object describing 'Exposed watch,' 'Partially buried watch,' 'Deeply buried watch,' 'Fishing lure,' and 'Rusted knife.' The background should have natural lakebed textures and silt patterns. The style should be technical, clean, and easy to read for sonar users. See more
