10 Best Castable Fish Finder 2025 in the United States

The Lowrance HDS PRO 12 Inch Fish Finder/ Chart Plotter stands out with its advanced sonar technology and large, high-resolution touchscreen. The 1.2MHz Active Imaging HD and ActiveTarget 2 Live Sonar offer precise and detailed underwater views, making it suitable for serious anglers who need reliable and accurate information. The ability to support multiple sonar systems simultaneously is a significant advantage for those who want comprehensive coverage and different perspectives of underwater environments.

Its SolarMAX HD touchscreen is a user-friendly feature that works well even in bright sunlight and with polarized sunglasses, ensuring visibility in varying conditions. Connectivity is robust with NMEA 2000, Wireless, and Bluetooth options, plus smartphone integration for notifications, enhancing convenience and usability on the water. Its depth range is impressive, reaching up to 1,000 feet, which is ample for most fishing needs.

Portability might be a concern given its size and weight, making it more suitable for boat installations rather than being truly portable. Its sturdy build and multiple mounting options are beneficial for secure installation. The Lowrance HDS PRO is ideal for committed anglers looking for a comprehensive, high-tech fish finder with excellent imaging and connectivity features, while its size and portability may not suit those needing a compact, easily transportable device.

The Lowrance Elite FS 9 Fish Finder stands out with its advanced sonar technology. The Active Imaging 3-in-1 transducer provides CHIRP, SideScan, and DownScan features, which deliver highly detailed images of underwater structures and fish. With support for ActiveTarget Live Sonar, users can even see real-time movements of fish, adding significant value for fishing enthusiasts.

The device's 9-inch multi-touch screen is high-resolution and user-friendly, making it easy to operate even for beginners. It also includes preloaded C-MAP Contour+ charts, which are incredibly useful for navigating fishing spots with precision. These charts cover 8,900 U.S. lakes, providing detailed 1-foot contours for better fishing success.

Full networking capabilities allow integration with various other devices and systems, enhancing the fishing experience. However, this fish finder may not be the most portable option due to its size and weight (16 x 14.07 x 5.54 inches and 4.53 kilograms). Also, it requires a 12-volt DC power source, which may limit its use in remote areas without easy access to power. Despite these drawbacks, the Lowrance Elite FS 9 is a comprehensive and robust fish finder, ideal for serious anglers looking for advanced features and detailed underwater insights.

The Garmin Striker Vivid 7cv is a user-friendly fishfinder with a sharp 7-inch color screen that uses vivid scanning sonar palettes to clearly show fish and underwater structures. It comes with the GT20 transducer supporting Garmin’s CHIRP traditional sonar and ClearVü scanning sonar, which provides detailed, clear images for better fish detection. Its high-sensitivity GPS allows you to mark waypoints, plan routes, and check your boat's speed, making it useful for navigation as well as fishing.

The built-in Quickdraw Contours mapping is a plus if you want to create custom maps of your fishing spots. Connectivity via Wi-Fi to the ActiveCaptain app lets you easily transfer data, receive notifications, and update software, which adds convenience and keeps the device current. The device weighs 4.4 pounds and mounts on a surface with a tilt/swivel bracket, which is fairly portable but not as compact as some castable models designed specifically for handheld use.

This fishfinder is best suited for anglers who use boats and want a reliable, clear fish detection system with handy GPS and mapping features, rather than those seeking a lightweight, fully castable device to toss from shore. The Garmin Striker Vivid 7cv combines strong sonar capabilities and smart connectivity, making it a solid choice for boat anglers looking to improve their fishing experience.
