If you find this post helpful, please share it.

When a castable fishfinder is mentioned one of the names that’s most likely to come up is Deeper, the company has a wide range of castable fishfinders as well as a very good rating on all their different castable fishfinders. The Pro series which consists of the Deeper Pro, Deeper Pro+, and Deeper Pro+ 2 are three well-designed fishfinders that can help you find and catch fish easily. Each of the models in the Pro series is very compact and easy to use. You just need to pair with the Deeper fishfinder app, then cast the sonar in water and you will be able to view fish arches and more right from your phone. This Deeper Pro series review takes a look at the Deeper Pro, Pro+ and Pro+ 2. We’ll talk about the respective features that you get with each of these fishfinders as well as features of the Fish Deeper app.

Deeper Castable FishFinders – How it Works

Irrespective of whatever model of Deeper Sonar you decide to purchase, it must first be paired with the Fish Deeper app. Once successfully paired, you can either troll the sonar from a boat or kayak or you can cast it out (be very careful about casting out the sonar as it can hit a hard surface say rock, and this will most likely affect the functions of the device). Once the sonar is in the water and successfully paired with your phone, it will continuously ping out frequencies into the water and all scans from the sonar are displayed on the Fish Deeper app over Wi-Fi. It’s as simple as that.

Deeper Smart Sonar Pro Review

Deeper Pro review
Deeper Pro – The Cheapest model in the Deeper Pro series. Lacks GPS, yet a decent fishfinder. credit: Deeper.
The Deeper Smart Sonar Pro is the cheapest model in the Deeper Pro series. It’s a very compact fishfinder that lacks inbuilt GPS, yet is equipped with a lot of features that can help you catch more fish.

  • Design and Setup
  • The Deeper Pro sonar is very compact and lightweight, it weighs only 100 grams. It’s also easy to setup for the first time. It has a casting range of 330ft, a minimum scanning depth of 19ft, and a maximum scanning depth of 260ft. That’s greater than the 200ft scanning range and 150ft scanning depth of the Garmin Striker Cast. The Deeper Pro features two beam angles, low and high. It also can show the water temperature and has a target separation of only 1 inch.

    To setup Deeper Pro is a straightforward process that requires you to fully charge the sonar before pairing with the Fish Deeper app. Once the sonar is paired successfully with the app, you can choose to troll the Deeper Pro from a kayak or boat or cast it out to scan an area. All scans from the Deeper Pro are shown on the Fish Deeper app.

  • Connectivity
  • The Deeper Pro has Wi-Fi as its means of pairing and connecting to the Fish Deeper app. Wi-Fi allows for faster transfer of data between the sonar and the app. And it can also transfer data even without an internet connection on your phone.

  • Transducer and Frequencies
  • The Deeper Pro also offers you the option to choose from two beam angles, a narrow 15° and a wider 55° beamscope. The smaller beamscope allows you to scan a smaller area with a high 290kHz frequency that offers greater precision and clarity, while the wider beamscope will allow you to scan a wider area with a 90kHz frequency that has a greater depth penetration but lesser clarity when compared to the smaller beamscope. And with a target separation of 1 inch, Deeper Pro can show you really clear images of fishes and other objects under the water.

  • Bathymetric Maps
  • Although the Deeper Pro lacks inbuilt GPS, it can still generate a bathymetric map of the water by connecting to your phone GPS.

  • Battery Life and Power Rating

The Deeper Smart Sonar Pro comes with a 3.7V replaceable lithium polymer battery. It has a battery life of about 5 – 6hrs when fully charged, and it takes about 2 hours to fully charge the device. So, you will have to charge this sonar every time you decide to go fishing. It has a power rating of 110-240V and can easily be charged with a micro-USB cable. In other to prevent the battery from going dead, it’s recommended that you charge the Deeper Pro at least once every 6 months even when not in use. This will prevent the battery from getting damaged.
