This paper studies a self-made tool for a simple underwater probe to explore the mysteries of the ocean. The structure and working principle of the underwater detector are designed, and the fabrication process is introduced. Its performance and reliability in underwater detection are verified by experiments. The successfully designed underwater probe has the characteristics of light, easy to carry, good stability and remarkable detection effect, and can effectively explore the secrets of the deep ocean. The experimental results show that the high detection accuracy and accuracy can be achieved in the Marine environment, which provides strong support for the Marine scientific research work. Future research directions include further improving the performance and function of the detector to accommodate a wider range of ocean exploration needs and make a greater contribution to marine scientific research and resource development.
