Deeper Pro Castable Fishfinders – How it Works

Just like every other castable fishfinder on the market, the Deeper Pro series requires you to install the Fish Deeper app on your phone in other to view data received by the transducer on your phone. In other words, you first install the app on your phone, then pair the sonar with your phone. After successfully pairing sonar and phone from the app, you can now troll or cast the sonar into the water which will show you images of fishes and other objects underwater. It’s worthy to note that from my experience, it’s easy to setup and pair the Deeper Pro+ 2 to your phone.

Fish Deeper App and its Features

The Fish Deeper app is the app that must be installed on your phone in other to be able to view images of fish and other objects detected by the sonar while in the water. The app is available on both the Android and iOS platforms. You simply need to go to the respective platforms depending on the phone you use, install the app, and you can easily pair with any model of the Deeper Pro series.

I’m really impressed by the number of features present in the Fish Deeper app, it clearly shows that the company has put in a good amount of work. There are lots of features present on the Fish Deeper app that can help increase your chances of catching more fish.

  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 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 that shows only vegetation and water depth or raw that shows a more detailed images of fish.

  5. Display Sensitivity
  6. You 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+ 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. This can serve for reference purposes. Some of the available maps are premium and will require payment to access.

  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 sonars like Pro+ 2 which has inbuilt GPS can 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 Pro vs Deeper Pro+ Vs Deeper Pro+ 2 – Features Compared

Deeper Pro vs Deeper Pro+ Vs Deeper Pro+ 2 – Design Compared

One of the advantages of a castable fishfinder is that they are relatively compact and lightweight. In this regard, all three castable fishfinders in the Deeper Pro series are very compact and lightweight. This makes it very easy for you to handle and operate. While Deeper Pro and Pro+ have cases made of durable ABS material, the Deeper Pro+ 2 has a more durable case made of ABS mixed with titanium materials. The Pro+ 2 weighs just 90g compared to 100g of Pro and Pro Plus.

Each of these fishfinders is very easy to install, the setup process is very straightforward.

  • You need to first charge the fishfinder (each of the models uses the same micro-USB charger)
  • Install the Fish Deeper app on your phone. This app is available on both Google Playstore and Apple app store.
  • Put the sonar in the water which will automatically turn on, then pair the sonar with your phone from the fishfinder app you installed earlier.
  • You can either cast or troll the fishfinder in the water, and you should be able to view images of fishes directly from your phone.

Note that care must be taken when you choose to cast any of these fishfinders. You want to avoid hitting the sonar on a rocky surface as this will most likely affect its function.

In other words, each of the models in the Deeper Pro series is very durable and easy to use. Although, the Deeper Pro Plus 2 has a more durable design than the other two.

Deeper Pro Plus review
The Deeper Pro Plus is a well-designed sonar. It has an inbuilt GPS and has a better connection stability than the Deeper Pro

Deeper Pro vs Deeper Pro+ Vs Deeper Pro+ 2 – Connectivity

The Deeper Pro, Pro Plus, Pro Plus 2 all have Wi-Fi that allows for the transfer of data between the sonar and your phone. The Wi-Fi connectivity is relatively faster than Bluetooth, and the sonar works entirely without the internet. So, you don’t need internet connectivity on your phone to use any of these sonars. It also means that even if internet is enabled on your phone, the Deeper Pro will work without any need for internet connectivity. It transfers data to your phone via Wi-Fi. You need not worry about internet access while fishing.

Deeper Pro vs Deeper Pro+ Vs Deeper Pro+ 2 – Sonar Types and Frequencies

All three sonars have a maximum casting range of 330ft which is greater than what you get with Garmin Striker Cast. The Deeper Pro+ 2 has a higher depth penetration of 330ft compared to 260ft of Deeper Pro and Pro+. Moreover, Deeper Pro and Deeper Pro+ come with the same type of dual-beam transducer that offers two frequency modes, while Deeper Pro+ 2 comes with a transducer that offers three frequency modes. With Deeper Pro or Pro Plus, you have the option of choosing from a higher 290kHz with a 15° beamangle or a smaller 90kHz with a wider 55° beamangle. The 90kHz has a higher depth penetration and allows you to scan a wider area. Meanwhile, the 290kHz has a lower depth penetration and a smaller beamcope, but it allows for precision and shows a clearer image.

With Deeper Pro+ 2, you get to choose from three beam angles. A very high 675kHz frequency with a 7° beamangle, 240kHz with a 20° and a 100kHz with a 47° beamscope. You can use the low frequency to scan a wide area then use the higher frequency to horn-in for precision and clearer images.

Each of these three scans at a very fast rate of 15scans per second. However, while Deeper Pro+ 2 has a target separation of just 0.4 inches, Deeper Pro and Pro+ have target separations of 1 inch. So, you get better image quality with Deeper Pro+ 2.

Deeper Pro vs Deeper Pro+ Vs Deeper Pro+ 2 – Inbuilt GPS

Deeper Pro+ and Pro+ 2 have inbuilt GPS which is not present in the Deeper Pro. With inbuilt GPS in these two, they are capable of generating bathymetric maps without connecting to your phone’s GPS. The Deeper Pro will require your phone GPS to create a map. With bathymetric maps created by any of these fishfinders, you can mark your favorite spots like docking areas and other places of interest.

Deeper Pro vs Deeper Pro+ Vs Deeper Pro+ 2 – Battery Life

Each of these fishfinder comes with a replaceable battery that needs to be charged every now and then. With Deeper Pro and Pro+, you can get up to 5-6 hrs of battery life. It’s up to 8-9hrs with Deeper Pro+ 2. The charging type on all three sonars is a USB port, you can charge any of these devices with a micro USB charger. Moreover, Deeper Pro+ 2 supports fast charging. It takes less time to fully charge the device unlike the other two which take up to 2hrs or more to be fully charged.

With any of these fishfinders, you’ll have to fully charge the device every time you go fishing. This is just a necessary precaution so that you don’t run out of battery. It’s worthy to note that each of the Deeper Pro models is designed in such a way that the device automatically turns off when not in the water and switches back on when in the water, this helps greatly to get longer battery life.

If for any reason you have not used Deeper fishfinder for a long period of time, you are required to charge the sonar at least once in 6 months. This will keep the battery in good shape and prevent the battery from getting damaged.

Deeper Pro review
Deeper Pro – The Cheapest model in the Deeper Pro series. Lacks GPS, yet a decent fishfinder. credit: Deeper.
Obviously, the Deeper Pro+ 2 is the best choice if you want clearer images of fish and a longer battery life. It’s the most advanced of all three castable fishfinders. It’s also a more durable device and has a higher depth range. However, it will cost you more money. On the other hand, the Deeper Pro and Pro+ are still decent options to choose from. These two are very compact, durable and as well are very well capable of showing you where the fish are biting.
