Fish Finders Guide
Depth capability
Depth capability refers to the range at which the fish finder can accurately detect objects underwater. For shallow water fishing, a fish finder with a depth capability of around 250 feet would be sufficient. One example of such a fish finder is the Garmin Striker 4 with Transducer. This compact fish finder provides a maximum depth capability of 1,600 feet in freshwater and up to 750 feet in saltwater, making it suitable for various fishing environments. On the other hand, if you plan on deep-sea fishing or fishing in large bodies of water, you would need a fish finder with a significantly higher depth capability, such as the Lowrance HOOK2 12”. This high-end fish finder offers a depth capability of up to 1,000 feet with its advanced sonar technology, ensuring accurate readings even in deep, open waters.
Frequency
The frequency of a fish finder refers to the number of times the sonar waves are emitted and detected in a given unit of time. A higher frequency, such as 200 kHz, provides finer details and is ideal for shallow water fishing or identifying smaller fish. In contrast, a lower frequency, like 50 kHz, can penetrate deeper waters but offers lower resolution.
For those looking for a fish finder with a higher frequency, the Garmin Striker 4 with Dual Beam Transducer is a great choice. It operates at a frequency of 200 kHz, allowing for precise fish detection in shallow waters. On the other hand, the Humminbird Helix 7 Chirp MSI GPS G3N offers a wide range of frequencies, including 50 kHz, 83 kHz, 200 kHz, and 800 kHz. This versatile fish finder is suitable for both shallow and deep water fishing, with the ability to provide detailed imaging and target separation. Remember, selecting the right frequency is crucial in ensuring accurate fish detection and maximizing your fishing experience!
Power output
The power output of a fish finder is usually measured in watts and determines the strength of the sonar signal. Higher power output means a stronger and more accurate signal, leading to better depth penetration and detection of fish. For beginners or casual anglers, fish finders with power outputs ranging from 100-200 watts will suffice, such as the Humminbird PiranhaMAX 4 Fish Finder. It offers a dual-beam sonar system with a power output of 1600 watts peak-to-peak, allowing for clear imaging and fish identification. For more professional anglers or those fishing in deep waters, the Garmin Striker Plus 7Cv with Transducer provides a higher power output of 500 watts RMS, enabling precise and detailed imaging even in depths of up to 2,300 feet.
Screen size
The screen size not only affects the visibility of the underwater data but also impacts the overall user experience. Larger screens provide a more detailed and clearer view of the underwater environment, making it easier to identify fish and underwater structures. On the other hand, smaller screens are more compact and portable, ideal for kayaks or smaller boats where space is limited. To give an example, the Humminbird Helix 10 CHIRP Mega DI+ GPS G4N Fish Finder boasts a generous 10.1-inch full-color display, providing a vivid and detailed representation of underwater data. Another option is the Garmin Striker 4” Fishfinder, featuring a compact 4-inch color display which is perfect for anglers who prefer a smaller and more portable setup.
Display resolution
Display resolution refers to the number of pixels that the fish finder's screen can display, which ultimately determines the clarity and detail of the images produced. A higher resolution provides sharper and more detailed representations of the underwater environment, allowing anglers to spot fish, underwater structures, and other vital details more easily. For instance, the Humminbird Helix 5 offers a resolution of 800 x 480 pixels, providing clear and crisp imagery, while the Garmin Striker 7SV boasts an impressive resolution of 800 x 480 pixels as well as side scanning technology for a greater view of the underwater area.
Sonar technology
This technology uses sound waves to detect underwater objects and determine the depth and contours of the water. One great example of a fish finder that utilizes sonar technology is the Garmin Striker 4 with Transducer. It offers CHIRP sonar that provides crystal-clear images of the underwater environment. Another option is the Lowrance Hook2 4X Fish Finder, which includes a wide-angle Broadband Sounder that enables easy tracking of fish and structures beneath the boat. For those looking for advanced sonar capabilities, the Humminbird Helix 7 Fish Finder is a notable choice. It features Dual Spectrum CHIRP sonar with SwitchFire technology, providing precise and detailed imaging of the water column.
Transducer type
The transducer sends out and receives sonar signals, translating them into images on your fish finder display. There are different types of transducers to suit different fishing conditions and boat setups. For shallow water fishing or small boats, a transom-mount transducer, such as the Garmin STRIKER 4cv, is a great choice. It can be easily attached to the back of your boat and provides accurate bottom tracking and fish targeting. If you have a larger boat or prefer a more versatile option, a thru-hull transducer, like the Lowrance HDI Skimmer Transducer, is a popular choice. It is installed through the hull of the boat and provides clear imaging even at high speeds. Split-beam transducers, such as the Humminbird XNT 9 20 T are ideal for improving target separation and reducing interference from other equipment. They are suitable for both fresh and saltwater fishing. Finally, if you are looking for a portable transducer to use on different boats, an ice fishing transducer like the Vexilar FLX-28 can be easily adapted for use in ice fishing conditions as well.
Waterproof rating
This is crucial as it determines the device's ability to withstand water exposure without getting damaged. For instance, the Garmin Striker 4 is an excellent choice with a waterproof rating of IPX7, meaning it can resist water immersion up to 1 meter for 30 minutes. Another reliable option is the Lowrance HOOK2-7 fish finder, which boasts an IPX7 waterproof rating as well. It's important to note that a high waterproof rating ensures the fish finder remains functional even when exposed to rain, splashes, or accidental submersion, providing peace of mind during your fishing adventures.
GPS capability
Having GPS functionality on your fish finder can greatly enhance your fishing experience by providing you with accurate positioning and navigation. A great example of a fish finder with GPS capability is the Garmin Striker Plus 7sv.

Another great option is the Humminbird Helix 7 Fish Finder. It utilizes Dual Spectrum CHIRP sonar to deliver clear and precise images of the underwater environment. Both of these fish finders offer excellent bottom contour imaging capabilities and will greatly enhance your fishing experience.
Fish arch identification
Fish arches are crucial as they represent fish swimming in the water. A high-quality fish finder should have advanced sonar technology, such as CHIRP or dual-frequency sonar, to provide detailed and clear arches. For example, the Garmin Striker 4 with Transducer utilizes CHIRP sonar to display well-defined fish arches, allowing anglers to easily differentiate between fish and underwater structures. Another excellent option is the Lowrance HOOK2 4X Fish Finder, featuring auto-tuning sonar, which is beneficial for instantly capturing fish arches without manual adjustments. It's crucial to choose a fish finder model that excels in fish arch identification for a more productive and enjoyable fishing experience.
Split screen display
This allows you to view multiple sonar information simultaneously, providing a more comprehensive and detailed picture of what's happening underwater. A great example of a fish finder with split screen display is the Lowrance Elite Ti2. It features a multi-window display that allows you to view a combination of sonar options, such as SideScan, DownScan, and traditional CHIRP sonar, all at once. This gives you the ability to easily compare different views and quickly identify fish and underwater structures. Other fish finders with split screen display options include the Garmin Striker Plus 9sv and the Humminbird Helix 7. These fish finders offer split screen functionality with various customizable viewing options, enabling you to optimize your fishing experience for different conditions and locations.
Multiple beam angles
