Things to Consider While Buying Fish Finder under $400

If you’re in the market for a fish finder and you’re looking to stay under a budget of $400, there are a few key things you should consider before making a purchase.

First, think about the type of fishing you’ll be doing. If you’re primarily fishing in freshwater, you may not need as advanced of a fish finder as someone who is fishing in saltwater. This can help narrow down your options and ensure you’re getting the most value for your money.

Next, consider the display size and resolution. A larger display will make it easier for you to see what’s happening beneath the surface, but keep in mind that it may also make the unit more expensive. Look for a display with at least a 480×480 resolution for clear and detailed images.

Another important factor is the frequency of the transducer. Higher-frequency transducers will provide better resolution and a clearer picture of what’s below the surface, but they may not penetrate as deeply as lower-frequency transducers. Consider what type of fish you’re targeting and at what depths you’ll be fishing to determine the best frequency for your needs.

You should also think about the type of transducer you want. There are two main types: transom-mounted transducers and trolling motor transducers. Transom-mounted transducers are the most common and are mounted on the back of the boat while trolling motor transducers are mounted on the trolling motor itself. Trolling motor transducers are a good choice if you want to be able to see what’s directly beneath your boat in real time, but they may not provide as wide of a coverage area as transom-mounted transducers.

Other features to consider include GPS capability, which can be helpful for marking fishing spots or navigating back to your starting point, and the ability to connect to a smartphone or other device for additional features and capabilities.

When shopping for a fish finder under $400, it’s important to set your priorities and decide which features are most important to you. Carefully considering these factors will help ensure you get the best fish finder for your needs and budget.

FAQs on Fish Finder Under $400

Does the fish finder drain the battery?

It is not possible for the fish finder to drain the battery. You should make sure your battery is fully charged and in good condition before using any of these features, as GPS and connecting to your smartphone can both draw additional power from the battery.

What kind of battery does a fish finder use?

In most cases, fish finders use 12-volt marine batteries, which need to be in good condition and fully charged before use.

How long will a 7AH battery run a fish finder?

Depending on how you use the fish finder, a 7AH battery should last around 4-6 hours. If you connect your fish finder to a smartphone or use GPS, that can drain the battery faster.

Do fish tanks run up a lot of electricity?

Fish tanks typically use a low amount of electricity. A fish tank’s main power source is the filter, which consumes between 10 and 20 watts. Other components like lights and heaters may also consume some power, but these are usually not significant.


Finding the best fish finder under $400 can be a challenge, but with careful consideration of features such as frequency, transducer type, GPS capability, and smartphone connectivity, you can find the perfect fish finder for your needs. Make sure to also consider battery life and power usage when shopping for a fish finder. The tips above will help you find the best fish finder based on your budget and needs.
