Fishing might be hobbyists’ favorite pastime and a source of revenue for avid fishermen. By using modern technology while fishing, you’ll have rewarding experiences and value for time. A fish finder is a simple gadget that helps you track an individual as well as schools of fish, the bottom of the waterbody, and underwater debris. You need to choose the best fish finder according to your own fishing style before embarking on your next fishing expedition.
As an outdoor and fishing enthusiast, it’s difficult to see through murky or clear water when tracking fish. In my opinion, manual tracking of water games are frustrating and can lead to long hours of exhaustion. Instead, I prefer high-quality fish-finding scanners that send underwater signals to pinpoint each fish’s location. Apart from their locations, such a gadget might display underwater structures and habitats that certain fish species like to live in and feed in.
The use of technology and its data interpretation has impacted on my expeditions quite positively. So, you might also consider this if you love fishing. In this buyers’ guide, I’ll enumerate the specifications of each item that has made our top pick. You’ll find all types of fish finders that are compatible with kayakers or handheld. Let’s learn how to choose the fish finder that fits your fishing style and purpose. Also, our reviews will help you make a comparison of sonar-enabled fish-finders, and any model that fits your budget.

Best Fish Finder Buying Guide
Now that we’ve gone through all the fantastic options in our elaborate fish finder reviews, let’s talk focus on the decisive factors behind making a buying choice. This is because so many different types of fish finders exist that your indecision might complicate this process. So, we can help you understand the basics of a finder so you can independently choose the best fish finder of your own.
- Stand Alone: Usually, the standalone type is not ergonomically enhanced. It has basic features of identifying the fish location and viable underwater spots around your boat. These types of fish locators don’t come with preloaded maps or expensive features. They are designed for low-budget buyers, inshore fishing, and conservative fishermen.
- Combo: You can get accurate details of underwater fish by combining many features. With the combo type, you understand the speed, depth, temperature and suppressor settings. Also, a combo model allows users to view maps, and understand the interpretation of data.
- Network: Technology makes handheld fish-locating devices unique. So, fish finders with active network systems are more improved than standalone options. Usually, network-enabled models use GPS to display route, track and share waypoints. It’s the GPS software that gives the exact direction to safety when you’re lost at sea. Also, users can enjoy Wi-Fi, and the Bluetooth connectivity that enables downloading of maps, and synchronization with mobile phones.
- Frequencies: The frequency of your find locator determines what is seen underwater. Different frequencies for handheld models might vary between 50, to 200 kHz. However, those that come with modern transducers can send higher frequencies suitable for offshore fishing. Depending on the depth of water and frequency strength, you can view different sizes of fish and shapes of underwater structures. Also, the transducer with dual, single or multiple frequencies should display on-screen images and locations of fish around your boat.
2. Power & Wattage
Electrical power is the source that keeps such devices active. However, the wattage rating indicates how fast and far the transducer unit emits its frequencies. When processing data, the response time increases if it has more wattage.
Also, the screen of your fish locator will refresh faster if the device has a higher watt rating. Usually, a 100-W rated fish finder with a frequency of 50 kHz will scan 400 feet of depth. You’ll need less wattage for shallow waters. So, your fishing style and purpose must align with the desired type of fish locator.
3. Design & Durability
It’s unlikely that buyers will not check for fish finders with ergonomic features before payment. Generally, the aesthetic design of fishing accessories indicates the quality of the brand. Buyers also consider the functionality of fishing gadgets, and their ease of use before making informed decisions.
We always recommend considering durability as a vital factor. When looking for this instrument, check whether the keypad buttons, housing, and other units are sturdily designed. The thought of early replacement with a new gadget shows a lack of durability.
So, consider high-quality devices that can withstand the effects of saltwater or weather. Durability is a factor that can give more value for money.
There are more cons with traditional fish finders that come as a fixed unit. Usually, older versions of fish finders require a hardwire connection with your unit before using it in your motorized watercraft. This manual connection makes the ease of portability quite difficult.
Watercraft owners that operate in exact locations can mount the transducer either on the hull or stern. Portable fish finders use either a rechargeable battery unit or disposable AAA batteries. These types are either installed with transom mounts on a kayak or used as handheld devices.
Also, ‘fly-in’ and ice fishermen can cast the transducers of portable models into the water when ice-fishing. The transducer is always attached to the transom mount with its suction cup.
- Size: Generally, buyers have more challenges finding fish-finding devices with smaller screens. So, models with bigger sized screens give better and clearer picture quality. Numbers and tiny details like fish icons, echoes, sonar arches, and other data on the display screen are easier to notice with large screens.
- Screen resolution: With adequate color pixels, they can show greater details and sharper images. Ideally, buyers need fish-finding devices with screen resolutions of at least 240(v) x 160(h) pixels. Usually, fish finders with better resolutions are more expensive and attractive.
- Screen color: Their screens are clear when they display colored images, but you’ll find brighter images with advanced models. Cheap models with glowing screens are better than old black and white versions if they allow you to see colored images under intense sunlight.
This type has a technical unit that transmits and receives sonar waves. Your fish radar is just an inactive tool without a transducer. As a sensitive, a range-finding unit, transducers also operate on frequencies and receive data.
Usually, transducers with wide, signal cone angles are suitable for small lakes, and the types with narrow, signal cone angles will fit the purpose of ocean fishermen. There are multi-purpose transducers that emit multiple beams. These types of transducers are designed to scan larger underwater areas and 3D display images.
Additionally, the side beam transducer includes areas around the sides of boats while searching for fish. When the transducer makes contact with water, it will either display data on the fishfinder or Smartphone’s screen.
The Global Positioning System (GPS) uses satellites and navigation technology to pinpoint locations, and give coordinates of positions. This software can also help fishermen mark hot fishing spots (waypoints), track and share them with friends.
Usually, fish finders with GPS units have memory space that allows for large storage of data location. So, the GPS can help you trace your direction back home when you’re lost at sea. However, you might not find many models with GPS capabilities.
Your data will be accurate while using highly sensitive devices. However, the accuracy of data increases when their cone angles are transmitted in shallow waters. Different cones can be displayed, and you’ll experience wider cone angles while fishing in deep water bodies.
Perhaps the price is the most important factor that determines your buying choice, aside from other accessories that might need to be in your boat’s toolbox. Typically, the price tag for high-quality products ranges between $100 to over $1000. You can get the most premium model under 2000 bucks. If you don’t want to break the bank, there are decent models that are affordable for you. You can also buy a refurbished or discount fish finder if you are on a shoestring.
How Does a Fish Finder Help You Find Fish?
The fish finder is a digital tracker and transducer that sends sonar signals just like a fathometer. Like a fishing drone or an underwater camera, its job is to assist you in finding fish. It gives information on the fish location and underwater structures. This works equally well for kayak, canoe, regular boat, Jon boat, and pontoon boat. Many models can read your boat’s traveling speed, and give details on your navigation. Generally, humans and animals generate electronic impulses that can be tracked by a sonar device.
As digital gadgets with sonar systems, fish finders work by using waves to detect those sound waves and impulses that have been reflected by a group of fish. Wave and sound are forms of energy that can be converted by the device. This data is displayed as digital and graphic images on the screen.
So, when in search of fish; you’ll see underwater organisms, obstacles, and bottom structures with a high degree of accuracy. Usually, these devices use different types of imaging and sonar technology. They all have their pros and cons; let’s see what’s unique to each imaging technique.
1. Side Imaging
Fishfinders that offer side-imaging displays emit beams to track your surrounding environment. Instead of seeing what’s beneath your boat, this type of sonar gives wide views of water structures around you. However, your area of view is the radius that a side-imaging sonar can sense.
Most fish finders don’t have side-imaging sonar technology but can work with side-imaging software. The need to position their sensors well might make it harder and more expensive to install the software on fish-finding devices.
2. Down Imaging
Fishfinders with down-imaging software are better than regular models of devices with sonar technology. However, sophisticated models come with down-imaging features.
Also, you view clear images of underwater fields of weed and fish with the zoom-in function. It’s the down-imaging sonar technology that helps spot where the fish are swimming around. You can toggle between the regular and down-imaging systems with your device.
3. Standard Sonar
This is a simple gadget that comes with standard sonar technology. When sonar beams are transmitted to the sea’s bottom, the reflective sound is received by the device. It’s the standard sonar model that displays cones and arcs to indicate the location of fish.
However, the standard sonar is inexpensive but not very accurate. Most times, they give rough and inaccurate data of the sea’s depth but work very well when finding fish.
Tips on Using Your Fish Finder
Follow these tips to improve the chances of landing a bigger catch and impress all.
1. Read the Operational Manual
Carefully go through the operational manual before operating the device.
2. Set Up the Device
Mounting the fish finder is part of the setup process. Make sure you place it in the right spot of your boat. Most products come with suction/swivel transom mounts; trolling, or hull, mounts for your boat. Some fish finders have auto-sonar mode while others have manual modes. For the modern fish finder, switch ‘ON’ the device, make basic connections, and use the pre-program settings to scan water bodies. You can use a float tube mount if needed.
3. Sensitive Settings
The power output rating of a fish finder can affect sensitive functions. However, anglers can adjust the settings and watch values displayed on the screen. It’s important for fishermen to get the right setting because unlike manual configurations, this will help locate fish automatically. While the auto-sonar is active, it’s easy for you to see the depth measurement of underwater bodies. The depth cursor also indicates the distance from the boat to the fish.
4. Suppressor Setting
Switch ‘OFF’ the transducer’s suppressor button to prevent interference with its sonar waves. It’s the suppressor setting that helps your device reduce background noise while scanning your waypoints for fish activities.
