These two are the most advanced as they are among the very few castable fishfinders that offer CHIRP sonars. This in-depth Deeper CHIRP 2 review takes a look at all the features of the Deeper CHIRP and CHIRP 2 so you know what you get with any of these fishfinders. Are they any good? Well from customers’ experience and reviews, it’s very obvious that Deeper CHIRP and CHIRP 2 can make a wise investment for your fishing goals.

Deeper CHIRP 2 - A compact fishfinder with long battery life
Deeper CHIRP 2 review

The Deeper CHIRP 2 is a higher-end version of the Deeper CHIRP. It’s more durable with a longer battery life and longer casting range. The CHIRP 2 is a fantastic fishfinder, it’s very easy to setup and use, and with CHIRP sonar, it can show you very images of fishes that results in lesser time on the water and more fishes.

What is CHIRP

Before we talk about the respective features of Deeper CHIRP and CHIRP 2, let’s define what a CHIRP is.

Unlike a traditional sonar that sends out a single frequency beam at a time, CHIRP sonars (Compressed High-Intensity Radiated Pulse) sends out a continuous flow of frequencies ranging from low to high. As a result, it offers far more image clarity that lets you easily detect and catch more fish. CHIRP is a regular feature on high-end transducers, but this feature is now available on castable fishfinders like Deeper CHIRP and CHIRP 2.

How to Use Deeper CHIRP 2

It’s important to know how the Deeper CHIRP and CHIRP 2 castable fishfinders work.

Just like other castable fishfinders, the Deeper CHIRP requires the Fish Deeper app to enable you to see fish and other objects in the water. This is slightly different from a regular fishfinder which has its own display screen as a separate device that can be connected to a transducer via a cord. But in the case of a castable fishfinder, your phone acts as the display that lets you see what’s going on in the water.

The Deeper CHIRP and CHIRP 2 are both equipped with WiFi that allows you to pair the fishfinder with the Fish Deeper app installed on your phone.

The first thing you need to do when you receive the Deeper CHIRP or CHIRP 2 is to install the Fish Deeper app on your phone. The app is available on both Apple app store and Google Playstore. Once the app is installed, charge the fishfinder to full, and cast it into the water. The fishfinder will automatically turn on, and then you can pair it with your phone from the Fish Deeper app. Once successfully paired, you will now be able to see fish and other objects in the water right from your phone’s screen.

Fish Deeper app – Some of the Available Features

Because the Fish Deeper app acts as the display that allows you to see fish and other objects in the water, the company has really put in a lot of effort as evident in the huge number of features present on the app. What I really like about the Fish Deeper app is that it’s very intuitive and also easy to use.

  1. Choose Your Preferred Color Palette
  2. The app allows you to choose your preferred display color depending on the time of the day you’re fishing. This will allow you to get the best viewing experience irrespective of the ambient light conditions of the environment. You can also turn on the night fishing feature to enable you to see the sonar scans better in the dark. The night fishing feature can only work with the Deeper Night Fishing Cover which is sold separately.

  3. Choose Sonar Display Mode
  4. The app also allows you to choose the display mode. You can choose between basic which shows only vegetation and water depth or raw which shows more detailed images of fish.

  5. Display Sensitivity
  6. You can also choose the display sensitivity. You can choose between high and low sensitivity. Low sensitivity is best for dirty water while high sensitivity is best for clear water.

  7. Fish Icons
  8. The app will also allow you to choose to enable or disable fish icons. You can show fish icons on the screen, their depth in the water as well as turn on or off the fish alarm that goes off when a fish is detected.

  9. Choose Beam Angle
  10. You can select your preferred beam angle depending on the sonar type you’re using. You can select from low or high for the Deeper Pro series, while you can select from low, high, or mid if you own a Deeper CHIRP sonar or the Pro Plus 2. The selected beam angle determines the area scanned as well as the quality of the sonar return. A low beam angle offers the best clarity but a smaller area is scanned while a high beam angle will allow you to scan a wider area, but with less clarity.

  11. Choose Fishing Types
  12. The app also allows you to choose your preferred fishing type. There are four fishing types; standard, ice, boat and onshore fishing types. The fishing type selected will determine the amount of information shown on the display.

  13. Mark Favorite Spots and Log Your Catches
  14. Just like a regular fishfinder, the Fish deeper app will allow you to mark your favorite fishing spots, and you can also log your catches. This will allow you to plan better and save more time.

  15. Download and Use Offline Maps
  16. The app also gives you access to download and use offline maps, which can serve for reference purposes. There is a huge range of maps that you can download for free for your preferred location. It’s recommended that you download offline maps using your phone’s internet connection as it’s faster. Meanwhile, while there is a generous list of free maps, a few maps are premium and will require payment to download.

  17. Create Bathymetric maps
  18. All Deeper sonars except the Deeper Start and Pro will allow you to create a bathymetric map of the water where you fish. Deeper fishfinders like Pro+ 2, CHIRP and CHIRP 2 have inbuilt GPS that allows you to create a bathymetric map directly from the device while those without inbuilt GPS like Deeper Pro will connect to your phone GPS to generate a bathymetric map.

  19. Explore Full Scan History
  20. You can explore a full scan history from your Deeper sonar in the app. This allows you to see what you might have missed. There is now a live scan history that allows you to access scan history without pausing the sonar.

  21. Automatic Sonar Update and Continuous Fish Deeper Updates

The Fish Deeper app will enable automatic updates for your Deeper sonar, while the app is continuously being updated with more features and bug fixes.

Deeper CHIRP Review

The Deeper CHIRP is the first model in the CHIRP series, yet a well-designed fishfinder that is very compact, easy to use, and also has a long battery life that lets you fish longer.


The Deeper CHIRP is a very compact and lightweight fishfinder that’s durably built with ABS materials. It’s suitable for kayak owners as well as bigger boat owners. It’s also a great fishfinder for ice fishing. The Deeper CHIRP is designed in such a way that once it’s in the water, it’s automatically switched on and can connect to your phone. And when you remove it from the water, it will automatically turn off. This way, it saves battery life.

To setup this fishfinder is very easy. You only need to charge it to full, then cast it in the water and pair it with the Fish Deeper app installed on your phone.


The Deeper CHIRP is equipped with WiFi for connectivity, which allows it to pair with your phone, and it has a long connection range of up to 100 meters. I must say that, unlike Deeper Start and Deeper Pro fishfinders, the connection between the sonar and your phone is fairly stable even when distance apart.

Unlike Bluetooth connectivity, WiFi on Deeper CHIRP allows for faster transfer of data in real-time to your phone. The good thing here is that the Deeper CHIRP does not require internet connectivity to transfer data to your phone. So, even when there is no Internet connection on your phone, you will still be able to find and catch fish with the Deeper CHIRP fishfinder. And when the internet is enabled on your phone, the sonar doesn’t use it, it will transfer data to your phone without using the internet. This is one of the fine features of the Deeper CHIRP fishfinder.

Sonar and Available Frequencies

The sonar that comes with Deeper CHIRP offers CHIRP in real-time. It has a casting range of 330ft which is among the longest you’ll get on the market. The depth penetration is also up to 330ft allowing you to target fish species far below the water surface.

With a very high target separation of 0.4 inch, the Deeper CHIRP will allow you to see clear images of fish. You have the option to choose from three frequency modes; a 100kHz frequency with a wide 47° beam angle, a higher 240kHz with a smaller 20° beam angle, or a very high 675kHz with an even smaller beam angle of 7° The highest frequency offers the best image quality but has the least depth penetration. Meanwhile, the smallest frequency offers the highest depth penetration but the least image quality. So you can use the low frequency to scan a wide area, then use the high frequency to horn in on your target.

Three sonar modes are available to choose from. You can choose from standard, boat, and ice fishing. And you can choose to troll or cast the Deeper CHIRP. Trolling at a very slow speed offers the best sonar returns while also showing the water depth and water temperature.

Bathymetric Maps

Just like Deeper Pro Plus 2, the Deeper CHIRP also has an inbuilt GPS that allows it to generate a bathymetric map as you fish. This means that you don’t need to carry your phone along to generate a map. The maps generated can be viewed from your phone.

A bathymetric map will help you understand the typographical scope of the water you fish. You can also mark your favorite spots like parking spots, launching points, fishing hotspots, and more. This will allow you to plan your next travel on the water more effectively.

Battery Life

The Deeper CHIRP comes with a rechargeable battery that has a 950mAh capacity. It has a battery life of up to 8hrs and takes about 1 hour 30 minutes to fully charge. The battery is also replaceable, just in case the battery stops working for any reason. Charging the fishfinder is easy, it comes with a micro USB charger with a power rating of 110-220V.

It’s recommended that you charge the Deeper CHIRP at least once every 6 months even when not in use. This will prevent the battery from damaging completely.

Deeper CHIR 2 Review

Deeper CHIRP 2 review
The Deeper CHIRP 2 is a higher end version of the CHIRP


Just like Deeper CHIRP, the CHIRP 2 is a very compact and lightweight fishfinder. It is durably built with ABS and titanium materials which makes it very rugged and tough on the water and ideal for fishing in both freshwater and saltwater. It’s also one of the best fishfinders for kayak owners and even bigger boat owners.

The setup process is easy and similar to that of Deeper CHIRP. First, you need to install the Fish Deeper app on your phone, then charge the fishfinder to full and cast in the water. Once in the water, the CHIRP 2 will automatically turn on, and then you can pair it from the Fish Deeper app.

You can choose to cast it out or troll it from your kayak or another type of boat. A flexible arm mount sold separately will allow you to tightly mount and troll the Deeper CHIRP 2 from your boat.


Just like Deeper CHIRP, the CHIRP 2 also has WiFi for faster transfer of data to the Fish Deeper app installed on your phone. This also doesn’t need the internet to work. The fishfinder pairs with your phone via WiFi and then can show you clear images of fish, bottom contours, and other objects in the water without internet connectivity. So, irrespective of wherever you choose to go fishing, the Deeper CHIRP 2 will work.

Sonar and Available Frequencies

The CHIRP 2 comes with a sonar that offers you CHIRP in real-time. It pings out frequencies continuously which will allow you to get high image clarity. It offers three frequency modes, a low 100kHz with a wide beamscope of 47°, a medium 240kHz with a moderate beamscope of 20°, and a higher 675kHz with a narrow 7° beamscope. It has a stunning 0.4-inch target separation in the 675kHz frequency mode and 0.94-inch target separation for wide CHIRP.

The higher the frequency the smaller the beam angle, in other words, you can choose to scan a wide area with a low frequency and then use the higher frequency to precisely focus on your target.

The CHIRP 2 scans at a fast rate of 15scans per second resulting in better image quality. It has a depth range of 330ft just like Deeper CHIRP. While you might never scan to that depth, it feels good to know that your sonar has that capability.

The casting range of the CHIRP 2 is a whopping 394ft which is obviously one of the longest you’ll find on a castable fishfinder. The CHIRP 2 also shows the water temperature as well as the water depth.

Bathymetric Maps

The Deeper CHIRP 2 also has an inbuilt GPS that enables it to generate a bathymetric map as you fish on the water. The generated map can be viewed from the Fish Deeper app on your phone and it can serve for reference purposes.

Battery Life

The Deeper CHIRP 2 is powered by a rechargeable lithium-ion battery with a 1300mAh battery capacity. It is estimated to last up to 15hrs which is the longest among Deeper fishfinders. And considering that the CHIRP 2 is designed to automatically switch off when not in the water, you will get a longer battery life.

The device can be charged with a micro USB cable that comes with the CHIRP 2. It also supports fast charging, which takes less than 2hrs to be fully charged.

As I mentioned earlier in the case of Deeper CHIRP, you need to charge the Deeper CHIRP 2 at least once every 6 months even when not in use. This prevents the battery from completely going dead. It cost a significant amount to order a replacement battery and you really don’t want that.

Both castable fishfinders share a lot of features in common, although, the CHIRP 2 is a more equipped fishfinder than its predecessor. The CHIRP 2 has a more durable build that comprises ABS and titanium materials compared to the Deeper CHIRP with only ABS material. The CHIRP 2 also has a longer battery life as well as a longer casting range.

It will cost you a little more to get the CHIRP 2. Nevertheless, Deeper CHIRP is still a very nice fishfinder considering its durability, ease of use, CHIRP frequency, and a decent battery life. If you are really tight on budget, the Deeper CHIRP is no doubt a fine choice.


In conclusion, both Deeper CHIRP and CHIRP 2 are two outstanding castable fishfinders that can improve the way to fish. Moreover, each of these two offers a CHIRP that allows you to see clearer images of fishes as well as other objects in the water. In my opinion, the CHIRP 2 is one of the very best castable fishfinders out there.
