Marine electronics refers to the technology and equipment used on boats and ships to enhance navigation, communication, and safety. This includes devices like GPS systems, radar, and sonar, which help mariners determine their location, avoid obstacles, and find fish. Additionally, marine electronics encompasses communication tools such as VHF radios and satellite systems, allowing vessels to stay in contact with each other and shore facilities. These technologies are essential for both recreational boating and commercial shipping, ensuring safe and efficient operations on the water.
