What is a Boat GPS and Fishfinder Combo, and Why Do You Need One?
A boat GPS and fishfinder combo is a device that integrates global positioning system (GPS) technology with sonar imaging to help boaters navigate and locate fish. This combination allows users to see underwater structures and fish locations on a display screen while also providing precise navigation capabilities.
The National Oceanic and Atmospheric Administration (NOAA) recognizes the significance of these devices in enhancing safe and efficient boating and fishing experiences. NOAA defines a fishfinder as a sonar device that sends sound waves to detect objects underwater.
This technology operates by sending sound waves through the water. When these waves hit an object, they bounce back, enabling the device to create a visual representation of underwater features. The GPS component provides accurate location data, helping boaters stay on course.
According to the American Boating Association, GPS devices improve safety by allowing boaters to accurately track their position, reducing the risk of accidents or becoming lost.
Factors contributing to the need for a boat GPS and fishfinder combo include increased boating activity, the desire for recreational fishing, and the increasing complexity of water navigation.
An estimated 49 million people in the United States participated in recreational fishing in 2019, according to the U.S. Fish and Wildlife Service. The growth in this activity may continue, highlighting the demand for advanced navigation tools.
The importance of a boat GPS and fishfinder combo extends to safety, environmental awareness, and economic benefits from recreational fishing. Improved navigation aids in preventing accidents and enhancing fishery sustainability.
For instance, installing this technology can lead to better fish population management through informed fishing practices. The International Game Fish Association recommends utilizing technology to promote responsible fishing methods.
To address navigational challenges, experts recommend regular training for boaters in GPS and sonar technology. Increased awareness through boating education programs can enhance safety, as well as lessen the environmental impact of fishing practices. Additionally, utilizing eco-friendly fishing gear can further mitigate impacts on marine ecosystems.

Traditional 2D Sonar:
Traditional 2D sonar uses sound waves to create a two-dimensional image of underwater structures and fish. This sonar operates by emitting sound pulses and measuring the time it takes for the echoes to return. It is effective for basic fish detection and depth measurement. According to Humminbird, 2D sonar is the most common type used by recreational anglers. It is often the go-to choice for beginners due to its straightforward visualization of fish and underwater terrain. -
Down Imaging Sonar:
Down imaging sonar provides a detailed, photo-like image of what lies directly below the boat. This technology uses high-frequency sound waves that create a clearer and more defined image compared to traditional sonar. It helps anglers identify fish hiding in underwater structures. A study by Garmin in 2021 showed that anglers using down imaging reported increased catch rates, particularly in heavily vegetated or structured areas. -
Side Imaging Sonar:
Side imaging sonar offers a much wider view of the underwater environment by scanning both sides of the boat. This sonar technology is particularly useful for locating fish and structures away from the boat. It captures data over a wide area, allowing anglers to assess the landscape and find schools of fish that might not be directly below them. According to Lowrance, side imaging can offer views up to 100 feet on either side of the vessel, dramatically enhancing scouting capabilities.
Each sonar technology serves different fishing needs, influencing how anglers plan their outings. While traditional 2D sonar may suffice for novice fishers, down imaging and side imaging offer enhanced capabilities for serious anglers looking to improve their fishing outcomes.
