How to choose a cheap fish finder under $200

When looking for a fish finder under $200, pay attention to the following key features:

  1. Sonar Type
  2. Transducer frequency
  3. Screen Size and Resolution
  4. GPS Functionality
  5. Portability

We will discuss the above key features in detail to help you find the best fish sonar in the $200 budget.

Sonar Type

In the $200 budget range, the types of sonar available are:

  1. Traditional 2D Sonar: This is the most basic type of sonar and is available in all fish finders. It provides a 2D view of what’s directly beneath your boat. Fish are shown as arches, and the depth, structure, and bottom hardness can be determined based on the echoes returned.
  2. CHIRP Sonar: CHIRP stands for Compressed High-Intensity Radiated Pulse. Instead of sending a single frequency, CHIRP sonars send a range of frequencies, from low to high, and interpret the combined returns. This results in better target separation, crisp fish arches, clearer images, and fewer noise artifacts.
  3. Down Imaging (DownScan or ClearVu): This is a more advanced form of traditional sonar that provides a more detailed and photographic-like view of the water column and structures beneath your boat. It’s excellent for identifying fish from structures.

You should aim for a fish finder that offers Down Imaging and CHIRP sonar if it’s available within your budget. 

Transducer Frequency

The transducer frequency you should choose depends on the type of fishing you’ll be doing and the conditions in which you’ll be fishing. Here’s a general guide:

  1. High Frequency (Around 200 kHz or Higher): Best for shallow water fishing. High frequencies provide the finest detail but are less effective in deep water. They are ideal for detecting small fish and getting a detailed view of the underwater structure in freshwater lakes, rivers, and shallow coastal areas.
  2. Low Frequency (Around 50 kHz): Suitable for deep water fishing. Low frequencies penetrate deeper into the water but provide less detail. These are ideal for saltwater fishing, deep lake fishing, and commercial fishing.
  3. Mid-range Frequencies (Around 83 kHz): These provide a good balance between detail and depth, making them versatile for both shallow and deep water but excel in neither.
  4. CHIRP: If your fish finder supports CHIRP, this is usually the best option as it uses a range of frequencies for more detailed and accurate images. It’s effective in both shallow and deep water.
  5. Dual or Multiple Frequencies: Some fish finders allow you to switch between frequencies or even use multiple frequencies at the same time. This provides a more versatile fishing experience, allowing you to adapt to different conditions.

Choose the frequency based on where you’ll be fishing most often and what you need from your fish finder. If you’re a versatile angler who fishes in a variety of conditions, consider a fish finder that offers multiple frequencies or CHIRP technology.

Screen Size and Resolution

The screen size and resolution of a fish finder play a significant role in how easily you can interpret the data it provides. Larger screens and higher resolutions offer better visibility and detail.

In the $200 price range, you’re likely to find smaller screens ranging from 3.5 to 5 inches. The resolution at this price point is often around 480×272 or 800×480 pixels.

For quality fishing and boating, it would be best to aim for the largest screen and highest resolution available within your budget.

GPS Functionality

GPS functionality in a fish finder allows you to mark waypoints, create routes, and sometimes even view basic maps. This is particularly useful for marking fishing hot spots, navigating back to specific locations, and tracking your boat’s speed and direction.

In the $200 range, most fish finders offer basic GPS plotting capabilities. You can usually mark waypoints, and some models may offer basic trail plotting. It’s rare to find detailed cartographic features or advanced mapping options at this price point.

For a quality fishing and boating experience, a basic GPS fish finder should suffice. Being able to mark waypoints is often enough for recreational anglers. However, a unit that offers more advanced GPS features like basic chart plotting or even rudimentary map overlays, is worth considering.

Portable fish finders are often compact, lightweight, and come with a carrying case or handle. Many portable fish finders are also castable, meaning you can cast them into the water from the shore, or even boat.

Choosing a portable fish finder is ideal in several scenarios:

  1. Multiple Vessels: If you fish from different platforms—like a kayak, a rented boat, and a friend’s boat—a portable fish finder is a flexible solution that can move with you.
  2. Kayak and Canoe Fishing: Space is at a premium on small boats, and a portable unit often takes up less space and can be easily removed when not needed.
  3. Shore Fishing: Castable fish finders can be thrown into the water from the shore, giving you valuable data where a boat-mounted unit couldn’t go.
  4. Ice Fishing: Portable units are perfect for ice fishing as they can be easily moved from hole to hole.
  5. Budget: Portable fish finders are generally less expensive than larger, more complex units, making them a good option for beginners or those on a budget.
  6. Ease of Use: Portable units are often simpler and more intuitive, ideal for those who are new to using fish finders.

In summary, a portable fish finder is a versatile and practical option for anglers who value flexibility, simplicity, and convenience.

Is a cheap fish finder good for small boats

Yes, a cheap fish finder can be a good option for small boats, especially for those who are new to fishing or have basic needs. Affordable fish finders often come with essential features like basic sonar, GPS plotting, and small but readable screens. Their compact size is generally well-suited for the limited space available on a small boat.

However, it’s essential to understand that lower-cost units may lack advanced features like Side Imaging. The frequency options and depth range may also be limited. But for basic fishing needs, such as identifying fish arches and underwater structures in shallow to medium depths, a cheap fish finder can be quite effective.

If you’re fishing in a small boat like a kayak or a dinghy, you may also appreciate the portability that many cheap fish finders offer. Some can even be cast from the boat and send data back to a smartphone, eliminating the need for a fixed installation.

So, while you may miss out on some advanced features, a cheap fish finder can still provide valuable assistance in locating fish, marking spots, and navigating, making it a good option for small boats.
