If you’re looking for a top-of-the-list fish finder for a small fishing boat and that’s easy to use, provides clear and detailed images, the Garmin Striker Vivid 7cv is a great choice.


  • The high-contrast color palettes make it easy to distinguish fish and structure, even in bright sunlight.

The Striker Vivid 7cv has been a trusty partner in my angling adventures. The 7″ color display is more than just easy on the eyes, it’s been my window into the water’s hidden world, offering clear and detailed images. I’ve found the high-contrast color palettes invaluable, effortlessly distinguishing fish from structure, even under the glaring midday sun.

This finder came ready to hit the water with me, sporting a tilt/swivel mount, transom, and trolling motor mounting hardware and cable. Installation was a breeze, making it ready to use almost out of the box.

However, my experience with the this finder hasn’t been without its challenges. The size of the 7″ display, while great for viewing, takes up more console space on my boat than I initially thought.

Once I got the hang of it, though, it became an indispensable part of my fishing tool kit. Important to note that if you are after side imaging, you will need to check the slightly upgraded model STRIKER Vivid 7sv.

Max Depth: 330 ft

  • The device’s power conservation feature is clever—it’s on when floating and off when out of water. But this might not be everyone’s cup of tea, especially if you’re someone who prefers constant monitoring.
  • The Striker Cast has decent water resistance (IPX6 and IPX7 standards), but don’t push your luck by testing these limits. It’s built for possible spray and splash, but a deep dive isn’t on the agenda.

They enable you to make your own detailed fishing charts, a significant aspect you want to consider when you use a fish finder, as it can be a godsend when you return to those fish-laden waters.

But as with everything, it’s not perfect. The battery life and water resistance are great for a normal day on the boat, but for those rougher or longer trips, they may fall short. This is an important factor to consider when evaluating fish finder features for your specific needs.

Overall, the Garmin Striker Cast shines as a great fish finder for small fishing boats, delivering user-friendly operation, portability, and impressive functionality. These aspects are crucial to consider when choosing a fish finder, as they can take your fishing experiences to new levels.

What To Look For When Choosing The Best Fish Finder For A Small Boat

Finding a fish finder that is perfect for your boat can seem daunting with so many different models available in the market. To make your decision easier and help you choose the best fish finder, we’ve put together this comprehensive guide that discusses all the key factors you should consider. So, let’s dive in.


The screen is your window to the underwater world. It’s where you’ll be spending most of your time looking, so it’s crucial to get this right. Consider the screen size and resolution that fits your boat’s size and your budget. Larger screens offer more room to display data and are easier to read, but they also come with a heftier price tag and take up more space. Higher resolution screens provide clearer images of fish and finer details.

Size & Portability

The size and portability of your fish finder are significant considerations, especially for compact watercraft with limited space. Compact, portable fish finders can offer excellent performance without taking up too much room. However, remember that smaller units might mean compromising on screen size and some features.


When considering the fish finder that fits your needs, mounting options for securing it onto your boat will depend on your boat’s configuration and personal preferences. Some common mounting options include transom mount (easy to install, works well for small vessels), trolling motor mount (best for avoiding surface clutter), thru-hull mount (most reliable but requires drilling), and portable kits (best for rented boats).

Water Resistance and Durability

Since fish finders are often exposed to harsh marine environments, it’s vital they’re water-resistant and durable. Look for units with high IPX ratings (measure of water resistance), robust construction, and high-quality materials to ensure longevity.


The transducer is the “eyes” of your fish finder, sending and receiving sonar signals. Some offer single frequency, while others have dual or multiple frequencies for more detailed information. A dual-frequency transducer can be beneficial for deep-water fishing, giving detailed data on a wide area. Consider the type of fishing you’ll do when selecting a transducer.


Frequency correlates with how well the fish finder detects fish and other underwater objects. Higher frequencies (e.g., 200 kHz) provide better detail and resolution in shallow water. In contrast, lower frequencies (e.g., 50 kHz) penetrate deeper waters but with less detail. Your choice should reflect the water bodies you usually fish in.

Scanning Depth

Some fish finders are better suited for shallow waters, where schools of fish often gather, while others can scan deeper underwater, which is crucial when you’re fishing in varied terrains.

Assess your regular fishing environment, whether it’s freshwater lakes, rivers, or deep-sea fishing, to guide your choice of the right fish finder based on its maximum scanning depth of water. If you mainly fish in shallow waters and your primary concern is knowing depth to steer clear of hazards, then a basic fish finder could be a sensible choice


Imaging refers to the style of display. Down imaging gives you a detailed view of what’s beneath the boat, while side scan or side imaging provides a broad view of the area around. High-end models often offer both. Your choice will depend on the kind of fishing you do and the water bodies you frequent.


A fish finder with GPS can significantly enhance your fishing experience. It can help you plan the best navigation path, mark productive spots, track routes, and even create your own maps. It’s an essential feature for serious anglers and those who love to fish in large and unfamiliar bodies of water.

Maps and Chartplotter

Built-in maps and chart plotting are valuable for marking successful fishing spots and navigation. Some models offer detailed cartography, others allow you to draw your own maps, and many have both. Choose a model that caters to your navigation needs.

User Interface and Controls

The user interface and control system should be intuitive and easy to navigate, even in rough waters or at high speed. Look for a fish finder with clearly labeled, easy-to-press buttons, and a simple, clean interface.

Battery Life

For portable fish finders, a long battery life is essential. You need a fish finder that won’t run out of power in the middle of your fishing trip. Look for devices with reliable, long-lasting batteries, and always consider carrying a backup power source.

Price and Value for Money

Price is always a deciding factor, but don’t let it be the only one. Before purchasing a fish finder, consider the features and benefits that come with the device. A cheaper or more affordable fish finder may save you money upfront but could lack crucial features or fail when durability is tested. Investing in a high-quality fish finder could enhance your fishing experience and provide the best value in the long run.

Remember, selecting the right fish finder for you will ultimately depend on your personal needs, fishing style, and budget. With this guide, you should be well-equipped to make an informed choice. Happy fishing!

What is the easiest fish finder to use?

The Garmin Striker Vivid 7cv is often touted as one of the easiest fish finders to use, thanks to its intuitive interface and clear, vivid display.

What is the best budget fish finder?

The Garmin Striker Plus 4  is an excellent budget-friendly fish finder. Despite its lower price tag, it doesn’t skimp on essential features like CHIRP sonar and GPS.

Is a depth finder the same as a fish finder?

Not exactly. While both devices use sonar, a depth finder only provides information about water depth. A fish finder, on the other hand, offers much more detailed information, including fish location, underwater structures, and bottom contour.

What is the difference between a fish finder and sonar?

Sonar is the technology that fish finders use to detect and plot underwater structures, including fish. So, a fish finder is a device that uses sonar technology, but not all sonar devices are fish finders.

Is chirp better than sonar?

CHIRP (Compressed High Intensity Radar Pulse) is a type of sonar that sends out a continuous sweep of frequencies, providing more detailed and accurate data than traditional sonar.

Is high or low CHIRP better for shallow water?

High CHIRP is generally better when fishing in shallow water as it provides more detailed images. Low CHIRP, however, is better for deep water fishing as it penetrates further.

What does CHIRP stand for on a fish finder?

CHIRP stands for Compressed High Intensity Radar Pulse. It’s a type of sonar technology that provides more precise and detailed information than traditional sonar.

Does it matter which way your transducer faces?

Yes, for optimal performance, the transducer should be mounted parallel to the ground and facing directly down.

What should I look for in a fish finder?

Key features to consider when choosing the right fish finder include screen size and resolution, sonar type (traditional, CHIRP, side-imaging, etc.), GPS functionality, and ease of use.

Are expensive fish finders worth it?

The value of a high-priced fish finder depends on your fishing needs and style. More expensive units typically offer more advanced features such as high-resolution touch screens, CHIRP sonar, side-imaging, and WiFi connectivity. If these features will significantly enhance your fishing experience, it may be worth the investment.

Do I need maps on my fish finder?

Having maps on your fish finder isn’t necessary, but it can significantly enhance your fishing experience. They can help you navigate unfamiliar waters, mark productive fishing spots, and track your route.
