Top Fish Finder Reviews

We chose these fish finders based on their performance, ease-of-use, features, and other parameters. Let us know in comments if you have any queries about any of them.

1. Deeper CHIRP Smart Sonar

Deeper CHIRP Smart Sonar

The Deeper CHIRP is a triple beam, castable fish finder for any of your fishing purposes. From bank fishing, ice, bridge, boat, or even kayak this fish finder is a much needed tool in the tackle box for every angler of every skill level.

With the CHIRP’s ability to use both a wide and a narrow beam, an angler can quickly check a spot to see if fish are present then switch to narrow beam to locate the exact location of your desired fish.


The CHIRP is extremely effective and has many ways to effectively master its abilities. It has proven its ability to be reliable when I have used it in salmon fishing.

When having a hard time locating a bite, you can cast the CHIRP and read the average salmon depth, switch your gear to match the depth and for my team at least, we started catching fish everywhere!

The Deeper CHIRP also reads out water temperature, this is especially effective as most species of fish are easy to catch at certain water temps. It has increased my salmon and bass game 10 fold just by allowing me to easily read temp alone.

It has an extremely long casting range as it used WiFi instead of Bluetooth and can read down as far as 330 feet making. It’s great for sturgeon fishing as well.

The CHIRP is going to be one of the more expensive BUT WELL WORTH IT tools in your tackle box, but hey, you know what they say: “cheap things are not good and good things are not cheap!” They are extremely durable and worth every penny.

Bottom Line

The CHIRP has a ton of additional features beyond the Deeper Pro+. Its triple beam sonar alone makes it a much more accurate fish finder. Its size is smaller, its battery lasts longer and us just all around a better piece of technology.

Pros & Cons:

  • Easy and simple to use for ANY age
  • Multiple use case from shore, bridge, boat, kayak, ice, etc
  • Very accurate water temperature reading
  • switchable beam angles
  • GPS and Wi-Fi Enabled with Bathymetric mapping that allows you to look at your scanning later once off the water
  • Battery is only used when the Deeper is running and in the water.
  • The unit floats Incase of a line break
  • Extremely small and portable
  • It’s best to bring a second rod so you don’t have to keep switching from the Deeper to your rig.

2. Humminbird HELIX 5 CHIRP GPS G2 fish finder

Humminbird HELIX 5 CHIRP GPS G2 Fishfinder Model

The best fishfinder for price on our list is the famous Humminbird HELIX 5 Chirp. If you are an angler that is looking for a top of the line fishfinder that comes with the powerful combination of switch fire, down imaging, side sonar, and a crystal clear screen display, then the Helix 5 is for you.

Needless to say, Humminbird single-handedly dominated the active fishfinder market, and while it is faced with a lot of competition, nothing has managed to come close to its line of amazing fish finders.


In our personal opinion, if there is any fish finder that can stand head to head with the Lowrance 000-11785-001 HDS-7 GEN3, it’s the 410210-1 HELIX 5 CHIRP GPS. The Helix 5 offers a sturdy and brilliant design that features 5-star small, medium and high-frequency modes to give you a greater view of depth to contours and underwater structures.

Helix 5 is one of Humminbird series that delivers an impressive screen resolution. Its 5-inch Ultra HD widescreen LED Backlit display provides you with 800 horizontal pixels by 480 vertical pixels.

Performance and Features

I must tell you: I adore the fact that the unit allows you to split your images into two halves of the screen easily and still gives you an excellent size chart plotter. Thanks to the Unimap and its Auto Chart Software that allows you to create your own custom contour and also give you a crystal clear detail of lakes, rivers, and coastlines.

One striking thing about the Helix 5 is that it’s incredibly easy to operate for both seasoned anglers and new anglers. Its most trusted and dedicated buttons allow you to save and bring up saved waypoints. You can as well take snapshots of images and zoom in and out your pictures.

The fish finder offers a Chirp Sonar and Transducer technology that comes with a 2d sonar and chirp imaging that lets you cover a broad range of frequencies and also provide you with better clarity between the targets and structures. These features combine to create an elegantly-executed fish finder that gives you just enough functionality while fishing.

Apart from the ability to differentiate between fish and structures, the Helix 5 also can go down to 1,500 ft. of water depth and has a transducer technology that lets you know the water temperature.

The Helix 5 is perfect for anglers who are looking for a fish finder with a GPS technology. With a built-in GPS, the unit allows you to navigate your way around the lake and keep track of your favorite fishing spot. The Unimap technology really makes the difference by showing you different inland coastlines, streams, boundaries and lakes.

In addition to that, the fish finder provides you with a sonar recording to keep records of a particular spot and save it for future reference. The battery life of the unit is quite impressive and can last for more than 7hours without going down.

Bottom Line

Having the Helix 5 as part of your fishing arsenal is a single investment you will never have to replace. Our experience with Humminbird Helix 5 has been extremely pleasant and amazing.
