Recommended Top 10 Best Fish Finder Reviews

1. Garmin Striker 4 Bbuilt-in GPS Fish Finder

Check Price

3.5-inch Screen

When compared to other finders, this screen is relatively small, but it still gets the job done. Since it’s in full color and has high contrast, you can still see everything quite clearly. The only downside is that you have to switch between menus, which can be a problem if you are trying to find fish and mark your location. Overall, it’s not necessarily a deal breaker, but it may be enough to warrant a larger screen. Fortunately, the Striker can come in bigger sizes if you want to upgrade.

Built-in GPS

Garmin made a name for itself in car navigation systems, so it makes sense that it would also be king of maps out on the water. What’s great about this finder is that you can mark your hot spots so that returning to them is even simpler. Whether you’re out on the open water or a river, you can track your progress quite easily.

CHIRP Transducer

As we mentioned, the strength of a fish finder is in how well it can locate the fish, which is why you need a high-quality transducer. CHIRP technology is one of the best you can find, and it provides a 200-watt RMS signal that can reach down to 1,600 feet in fresh water and 750 feet in salt water. Overall, you can find plenty of fish with this device.

2. Humminbird HELIX 9 DI GPS Fishfinder

Check Price

9-inch Screen

Unlike the Garmin above, this fish finder is built for those who want to see everything at once. With nine-inches of screen real estate, this is almost more like a tablet than a regular finder, making it a valuable addition to any boat. Best of all, the control panel is intuitive and enables you to work faster.

Dual Beam PLUS Sonar

While many fish finders point directly underneath your boat, higher end units like this one will sweep to the sides as well. Considering that you are casting out from the ship rather than dangling lines beneath it, side sweeping is much more valuable as it allows you to find fish wherever you are, rather than finding them, moving the boat, and then trying to catch them.

Internal GPS System

These days, if your finder doesn’t have GPS Combo, then you need to upgrade. Not only does it make it easier to pinpoint your location when you’re out on the open water, but it will help you mark hot zones so that you can return for a big haul next time.

3. Garmin Striker 5DV Fish Finder

Check Price

5-Inch Screen

If you want to upgrade your system from the Striker model above, then you need to get this 5DV model from Garmin. Not only does it have a larger screen, but it has more of everything you need to find your fish quickly and efficiently. Best of all, having more real estate means that you can do split screen with both the GPS and the transducer. This will allow you to plot hot spots even easier than before. Best of all, you can share this information with other Strikers, so your buddies can get in on the action.

CHIRP Sonar

This unit uses the same high-quality technology as the one above, but this time it’s even more powerful. It produces up to 500 watts of RMS signal and can reach depths of 2,300 feet in fresh water and 1,100 feet in salt water. Overall, this is a much better system for deep sea fishermen.

Rugged Housing

Although fish finders are built to be on the water, some models are relatively fragile and can get damaged easily. Thankfully, the Striker 5DV has a more rugged covering so that it can be bounced around a little bit (and get wet) without damaging the internal components.

4. Lowrance Hook-3X Sonar W/ 83/200 XDCR

Check Price

3-inch LED Screen

If you don’t need something that high-tech, then this finder from Lowrance might be a better option. This is a cost-effective finder that provides excellent readouts on rivers and lakes, but it may not work well for deep sea fishing. The three-inch screen has high contrast color readouts and displays all of the information you need, minus any GPS mapping. Overall, if you aren’t in the market for anything too fancy but you want something that’s reliable, this is a great option.

Advanced Signal Processing

One of the best things about this finder is that it comes with sophisticated software that boosts the signal automatically. This means that you don’t have to fiddle with the controls as much to get a clear picture. Instead, you can focus your attention on fishing.

Dual-Frequency System

The transducer that comes with this finder produces both 83 and 200 kHz signals so that you can see better in shallow and deeper waters. It’s easy to switch back and forth, and the clarity is great in either case.

Overall, this is as good as it gets.

Cartography with Maps and Navionics

The charting technology on this finder is incredible, which is why it has such a high price tag. You can find your location on the map and then scan the whole area and produce a high-quality, high-definition 3D reading. Finding fish has never been easier.

Four Channel Sonar Technology

Advantage of a Fish Finder

There are many benefits to using the fish finder for you. They work at any depth, provide you the information you need to catch fish and help map out your area. If you’re fishing at a new lake for the first time, using the perfect fish finder for you can immensely help you out. You can find the perfect route for finding the fish and spend less time wondering where they are. All the information they display allows you to concentrate on an area, instead of hopelessly floating along the water. Fish locators make fishing look easy, and you know when you have the perfect one for you.

When you have the right fish finder for you, you will notice the differences between fishing with and without one. Even if you’ve been fishing in the same place for 20 years, and have had some luck, knowing what’s under the water can help you. Not only will you catch more fish, but you can also avoid dangerous reefs and barriers hidden in shallow waters. Not only are you hauling in more fish, but you’re also safer when you know what is lurking underneath the waves. It’s a practical device you know you’ll need for any type of fishing.

Using Your Fish Finder: Best Practices

Once you get your fish finder, you may wonder what you need to do to make sure it works correctly. This step-by-step guide will help you get setup and ready to use the finder.

Check the Manual

To understand how your fish finder works, you want to consult the manual. You can read the terms, and how to program the finder. While you may not enjoy reading the technical babble, it is a good way to familiarize yourself.

Mounting the Fish Finder

You want to put the finder in the best spot on your boat. There are a few different types of mounts you can use. You can choose from a transom, trolling, hull, or portable mount for your boat. Depending on your wants and needs, you can choose the right mount.

Setting up the Fish Finder

You want to turn the fish finder on. It will be set in automatic mode already, with the pre-program settings already on. You can switch it to a manual mode at any time to customized the finder. When you first turn it on, you can leave it in the automatic mode. You then want to drive on the water in automatic mode to get an idea of what it’s seeing.

Adjusting the Settings

The first setting you want to understand is the sensitivity. This adjusts the power of the fish finder, allowing you to see more details. When the power is lower, the quality on display is lowered. You can toy around with the fish finder to find the right setting.

Adjusting the Fish ID Setting

When the fish finder is on the automatic setting, it will identify fish automatically. It’s ideal for those who are trying to figure out their fish finder, but once you adjust to it, you can turn it off. You can see the fish arches, which will give you a better view of what's going on underneath the waves.

Using Auto Depth

If you’ve never used sonar before, you want to keep the auto depth turned on. It automatically tracks the floor of the water, making it easier to see how far down it is. When you become more experienced, you can adjust the setting. The auto depth feature can be adjusted to hide the first few feet underneath, and above the true bottom. It’s useful for setting your sights on the fish you want to catch.

Depth Cursor

The depth cursor is a line that goes across the screen. This line will let you know how far down the fish are, which makes it easy to determine where to put your bait. It will move up and down on the screen, making it easy to find the fish.

Suppressor Setting

The suppressor setting is perfect for blocking out the background noise you’ll experience while you’re waypoints . This setting is normally automatic if the transducer is installed correctly, but you can adjust it for your benefit. You don’t want to keep the suppressor on all the time because it can block out the sonar.

How Does a Fish Finder Work?

Fish finders are an excellent tool that can enhance the fishing experience, and allow you to catch more fish. There are typically only two parts to a fish finder, making it easy for everyone to use. They have a screen or display that fits onto your boat and gives you the information you need to catch more fish. They will display how far down the fish are, and how deep the water is. A fish locator uses a transducer, which takes recordings of the area near the boat using sonar. The sonar bounces off fish, rocks, coral, and other objects under the water.

When the sonar comes back to the transducer, this information is relayed to the display screen. It’s a basic computer showing raw data of what lies underneath the surface of the water. It is easy to read and understand display that will help you find where the fish are swimming. They’re ideal for anyone who wants to get a better idea of the surrounding area under the water. Even if you use it for kayaking, it’s good to know whether you’re near any rocks or logs. You can avoid accidents and map out the water for other adventures if you’d like.

What is a Good Price for a Fish Finder?

There are a lot of factors that go into finding a right fish finder for the right price. Depending on the type of fishing you’re doing will factor into the price tag. There are some that are under $200, while others can run up to over $1000. You should consider where you’re fishing, what type of fish you want to catch, and what features you’ll need.

If you’re on a budget, you don’t want to spend too much money on a fish finder. Some of the finders are ones that do everything you want them to do, and won’t break the bank. If you’re looking for the ideal price for a fish finder, you may want to consider spending at least $300, but no more than $800. Unless you can afford some of the more expensive fish finders, your range should be between $300-600.

Final Verdict

Overall, if you want to get the best fish finder, then our top pick has to be either the Humminbird Helix 9 or the Lowrance HDS-9. We love the large screens and comprehensive functions that you get with both devices, as well as the rugged dependability. If you want to save money, though, the Garmin Striker 4 will be your next best bet as it comes with high-performance results, even with a smaller screen.
