Deeper Smart Sonar Pro

Ideal for anyone getting serious about smart sonar fishing, the Deeper Smart Sonar PRO transmits incredibly detailed data and has a huge operating range, all thanks to its inbuilt WiFi.

The Deeper Smart Sonar Pro takes smart sonar fishing to the next level. Its WiFi connection gives it incredible data transmission power. And it needs it, because, thanks to its higher scanning frequency and resolution, the Smart Sonar Pro gathers a lot of data. It can capture every detail of the site you’re fishing, including small and fast-moving objects. Using a WiFi connection also significantly boosts its range (80m / 260 ft), while its advanced sonar technology gives a scanning depth of 80m / 260ft. And using WiFi also guarantees rock solid connectivity, no matter what the conditions are.

These advanced features make the Deeper Smart Sonar PRO the right choice for serious anglers ready to massively up their game.

Advantages: wider casting range, more detailed data, rock solid connectivity
Best option for: seasoned enthusiasts, competitive anglers

WiFi connection

The Deeper Smart Sonar PRO uses a WiFi connection, enabling it to transfer much more data, giving it an increased range of up to 330ft/100 m, and guaranteeing rock solid connectivity. The WiFi connection does not require any internet connection to operate, and can be used anywhere.

Scan Deeper

The Deeper Smart Sonar PRO floats on the water and scans down to 260ft / 80 m below. Use this enhanced scanning depth to find every depth change and drop off, then hone in on the most productive fishing zones.

Hi-Res Structure Imaging

The PRO is kitted with a higher resolution scanner, enabling it to separate objects down to a distance of 0.4 inches / 1.3 cm. This allows you to identify smaller underwater units, so you know exactly what you are fishing for.

Create Detailed Maps

When operated in Boat Mode, the Deeper App combines the PRO’s detailed data together with GPS location data from your smartphone to create bathymetric maps in real-time. All maps are free to download through the Deeper App.

A powerful castable sonar

The Deeper Smart Sonar couldn’t be easier to set up and use. It’s small and ultra-light, so it’s suitable for casting using most standard lines. It’s the same size and weight as its Bluetooth forerunner, but comes with more powerful components, stronger connectivity and greater range. Now shore anglers can access echo sounder data with a level of accuracy that was previously available only from expensive on-boat consoles.


Wi-Fi Advantage

The PRO uses a WiFi connection to transfer more accurate and detailed sonar data to your smartphone or tablet. This WiFi connection gives the PRO an extended casting range of up to 330ft/100 m. Please not this WiFi connection is an independent wireless signal between your sonar and your smartphone or tablet, and does not require an internet connection or phone signal in order to work.


Connecting to your PRO

Connecting your smartphone or tablet to your PRO couldn’t be easier. Your PRO will turn on automatically when it’s in the water. Then simply to turn on WiFi on your smartphone or tablet, find the WiFi signal from your Deeper, and connect. No internet or phone signal is necessary. You can use your Deeper device anywhere in the world, so if your next fishing trip is in the Amazon rainforest, no problem.

Maximise connectivity: If you are casting your PRO long distances, it’s possible that you will experience connectivity issues. This is because, as the WiFi signal becomes weaker the further away it gets, your phone will automatically start searching for a stronger signal, which may cause disconnection. To stop this, simply turn off Mobile Data, and in the case of iOS devices WiFi Assist, and your phone will always stay connected to your smart sonar’s WiFi signal.

Higher Scanning Frequencies

Fast moving targets? The PRO has double the scanning frequency of earlier models, sending out 15 scans per second. This means it can capture faster moving objects underwater, making it easier to identify the fish below and meaning nothing will pass underneath your sonar undetected.
