3 Best Cheap Fish Finders (Reviews) in 2024
That fishing trip you’ve been planning with your buddies may yet establish you as the king of the lake if you bring along a powerful but inexpensive fish finder. One can easily find a good device with diligent research and reading. However, if you`d rather focus on practicing your fishing moves than sit down and scour the many pages of fishing websites, let us make things easier by recommending three fantastic products you can choose from.
1. Garmin Echo 151dv US and Canada with Transducer
Engineered to be powerful as it is effortless to use, the Garmin Echo 151dv is equipped with a four-inch display that provides 8-level grayscale plus 160 x 256 resolution. The device is built with the same specifications and features as its predecessor, the Echo 150.
The difference lies in the current device`s upgrades that include the DownVu, which is its down imaging capability. DownVu offers viewing of more details such as individual fish within a structure or swimming with a school. It increases the accuracy level of readings from about 40 feet and deeper.
The device also offers support for a separately purchased 50/200 kHz dual frequency transducer. Providing a power output of 200 watts RMS, along with 1600 watts peak-to-peak, the fish finder has a maximum depth capacity of 1600 feet.
The viewing cone graduates from narrow to wide so the angler can see images far beyond the sides of the boat, ranging from shallow to maximum depths. The split-screen feature allows side-by-side viewing of the traditional sonar and down image, with superb target separation and bottom tracking.
Pros
You will get more than a standard fish finder when you purchase this model, as its all-in-one transducer will offer you an almost photographic view of schools of fish.
The 8-level display lets you understand precisely how the fish moves and you can track what it happens underneath your boat and further with excellent efficiency.
You can extend your vision beyond just what takes place under your boat, as the sonar goes as far as 1,600 feet deep.
The tilt and swivel mount will come in handy and will prove very convenient when you want to employ the fish finder in one spot so that you can see about your fishing.
The display resolution is 160×256, giving you quite a clear picture of the fish.
Cons
You will have to wait a little while for the fish finder to start displaying readings, which can be a drawback, especially if you are not the most patient person.

2. Venterior VT-FF001 Portable Fish Finder Handheld Fishfinder
Able to detect and display structure elements along with natural ones such as short and tall weeds, sand, grass and rocks on the seabed, the Venterior Portable Wired Fish Finder lets you see more fish to catch on days out in the water.
Giving users the approximate location of fish, along with the depth of the water, this portable fish finder is equipped with a round transducer sensor that sends out sonar waves into the water. The sonar signal bounces off of objects under the boat and gets transmitted back to the device for immediate viewing as an image on the screen. Conveniently, the transducer comes with a 7.5-meter cable for stable power.
The Venterior Portable Wired Fish Finder offers a 45-degree beam angle that finds large submerged structure as well as fish, enabling users to zero in on the target in order to capture it more easily.
The device provides fish depth scale and is equipped with an audible fish alarm so the angler always knows where to find target fish. It even has a power saving feature that turns the unit off when not in use.
Pros
You will get a very accurate reading of what is happening in the water, and not only fish location, but also the placement of weeds, rocks, and other things on the bottom of the water body.
The transducer comes with a 25-foot cable, and the float can be removed; you can successfully use this device when fishing from your boat, when you go ice fishing, or even when fishing off a dock.
The depth range goes from one meter to 100 meters, but you must keep in mind that the depth is calculated from the sonar sensor and not the transducer’s float.
You can select sensitivity from 5 available settings, which gives you more control over what type of fish you want to monitor.
Cons
One issue that must be mentioned about this model is that the setting preferences do not remain saved after the unit shuts off.

Buying guide
Whether you get a really pricey unit or one of those cheap fish finders out on the market, you have to make sure the device you have will help you catch the most fish. If you’re serious about fishing, you can’t afford too many missed opportunities just because you own a really lousy fish finder. Here’s what to check out in this kind of equipment.
Transducer
Any self-respecting angler knows that even cheap fish finders should be equipped with a transducer. The transducer is the primary unit that emits and receives sonar waves, sending the sonar signal into the water. The signal then bounces off of underwater objects and gets picked up by the transducer. The data picked up through the device will be ìnterpreted as a picture that the user can see and understand.
Some models serve as all-in-one transducers that provide advanced high definition identification plus a scanning sonar to deliver a virtually photographic view of the structure and fish under the water craft. Others have a round transducer sensor that also does the same.
Frequency
The frequency is a huge factor in any transducer. Plenty of the best fish finder models come with 200 kHz frequencies, and sometimes 50, 83 and 192 kHz, all in direct relation to the cone angle.
While the higher frequencies such as 192 and 200 kHz are designed for optimal use in shallow water, low khZ devices such as 50 kHz provide superb fish finding capability in deep water. With higher frequency, a greater degree of detail can be detected and viewed on the display panel, thanks to the high number of sonar waves transmitted and received.
Cone Angle
The width of the beam sent from the bottom of the boat into the water is referred to as the cone angle. A larger area is covered when the degree of the cone is wider. Keep in mind that the sensitivity is inversely proportional to the width of the angle especially in deep water. Typically, transducer cones come in ranges between 9 degrees and more than 60 degrees, with most devices equipped with ranges from 16 to 20 degrees.

Fish finders explained. How do they work?
Most of the fish finders that are now available in the market rely on the same Sonar technology that was being used by troops in WWII. An easy way of understanding how these devices are capable of showing you data regarding fish, rocks, and pretty much everything that you might find underwater is by realizing that they emit sound waves. Once the signal has been let out, it keeps going through different layers of water until it stumbles upon an obstacle and then bounces back to the main unit. If the product doesn’t find a fish or anything else, it will keep going until it reaches the bottom of the water and then it will transmit the information accordingly, mainly by letting you know that there’s nothing to catch in that area.
The cone angle of a fish finder depends on the number of sonar beams that it can emit. The higher the number of sonar beams, the higher the chance you’re able to visualize greater detail as well as a larger area. The coverage area of most models out there ranges from 20 degrees to 110 degrees.
One of the crucial things that a fish finder user must come to realize is that the accuracy of the device largely depends on a series of factors. For example, if you do your fishing in deep, murky waters, you might have poorer results than if you were to fish in clear water. Besides, the accuracy of the transducer should be taken into account before choosing one product over the next. Transducers have a number of features that are most important for fishermen, such as frequency, cone angle, and depth capability.
If you were to ask yourself whether a 50 kHz fish finder is better or worse than a 200 kHz one, you might find that it’s actually difficult to give a straight answer. Transducers with a lower frequency are excellent choices for people who want to fish in deep waters, in spite of the fact that the amount of detail seen by the user might not be the best. By contrast, transducers with a higher frequency have a rather limited capability when it comes to providing in-depth readings, but they offer incredible detail. In other words, you ought to think about the areas where you plan to go fishing before buying a certain unit.
Based on the sonar technology that we’ve mentioned at the beginning of the article and thanks to the pressure and temperature sensitivity capability of the device, fish finders can do a great job of displaying the bottom structure and the fish that might be found under your boat. While the data representation mainly depends on the model and LCD you might have on your hands, in most cases, fish are depicted as small arches that come up on a graph that tells you the surface and depth where the target is located as well as the time it takes for the unit to provide the readings. As such, the speed of a fish finder also plays a significant role in your fishing success.
