Abstract

The ‘Davinator’ is a low-cost and portable system for mapping underwater habitats in shallow coastal waters. The system combines sonar data with photogrammetry, using a fish finder and GoPro camera inside a waterproof box. It can be towed by a snorkeler, kayak, or small boat. The data collected are processed to create detailed maps, depth profiles, and even 3D models of the seabed, enabling researchers to assess habitat types, identify areas of interest, and monitor changes over time. The Davinator is an alternative to traditional, more expensive methods such as diver surveys and multibeam sonar. It is a cost-effective and accessible tool for environmental management and research.
