Deeper Smart Sonar PRO+ - GPS Portable Wireless Wi-Fi Fish Finder for Shore and Ice Fishing

Deeper Pro+ has without a doubt taken the world by storm. What seemed impossible like using a fish finder from shore is now possible. 

This fish finder pairs wirelessly via Wi-Fi with an Android 4.0+ or an iOS 9.0+ device. Once the Deeper Smart Sonar touches the water, it starts transmitting directly to your device. It transforms your tablet or smartphone into a smart sonar fish finder. You can see the vegetation, underwater structures, depth, temperature, and locations where the fish are hiding.

If you are pro fisher, studying vegetation gives you a pretty good idea of where fish go to feed and the places they like to hide. Not to mention the capability of marking fish and seeing bait balls and fish arches as well as adding fish size icons and depth tags as you make more casts. 

The Deeper app paired with Deeper fish finders allows live GPS split scanning and mapping. It helps you know your favorite locations so that you can see where you’ve been and your favorite fishing spots as well.

Knowing the water temperature and depth is essential in staying at your target depth range especially when trolling. 

The Deeper app also includes fish notes, weather forecast, and a Lunar Forecast calendar to help plan a fishing excursion. With GPS onshore mapping you can create a detailed map live on your smartphone screen for future use.

How Does It Work?

The Deeper Smart Sonar PRO+ is small and lightweight, synchronizing with your iOS/Android device. It’s easy to install without using batteries or cables. Using Wi-Fi, it creates a ‘hotspot’ and connects to your phone or tablet without using your device’s internet data.

By casting out your Deeper PRO+ into the water you can immediately read water temperature and depth. This takes less time than normal casting and makes less of an impact on the water’s surface than using a typical marker float. The Deeper PRO+ is able to perform 15 scans per second allowing you to find fish, structures & vegetation while stationary or trolling.

After gradually reeling in the Deeper PRO+ the scanned mounds, drops and fringe shelves will be highlighted on your SmartPhone’s screen. You can successfully locate, monitor, and target fish while you angle to your heart’s content.

Every scan and map is saved onto Deeper PRO+’s bathymetric management platform, Lakebook. This helps you to quickly discover fishing hot spots and aim for the specific species & sizes you’re after. The data from each site you fish at is all stored as a complete summary to be available at a later stage for easy access and exploration. Using the Fish Deeper App through Lakebook is easy as it is compatible with any computer. 

Wi-Fi Connectivity

A unique aspect of the Deeper Smart Sonar Pro+ is that it emits its Wi-Fi field. This means it does not depend on cellular or internet data for connection. As long as your smart device and the Sonar Pro+ have some juice, you can fish away from civilization and never miss out on the big fish.

Maximum Depth

With a 330ft range, Deeper Pro+ can go even further. When cast you cast out the Deeper Pro+ can scan a depth of 260ft. Not to mention it can scan objects from as close as 2ft and can mark an object sized only 0.5inches at the maximum depth. 

Design Features 

This is a truly mobile fish finder weighing in only 3.5 ounces and 2.5inches in diameter. This device boasts a dual beam frequency using a wide beam (290kHz) that can see out to 55 degrees and a narrow beam (90kHz) that casts a 15-degree cone. Whether you want a small or big picture, the details of the image will be crisp clear. 

The Deeper Pro+ seems small, but this is a rugged device that can withstand impact thanks to its tough ABS construction. 

You have four fishing modes including standard, boat, Onshore GPS mode, and ice fishing.

1. Shore Fishing 

With the help of GPS, the Deeper Pro+ allows detailed bathymetric mapping from the shore. All the maps and scans are saved on the app so that you can access your history on your smartphone or a computer. It helps you to learn different fishing conditions and locations as well as the temperature and depth.

2. Kayak Fishing 

This device will install on your kayak with only clamping and unclamping. This way, you can use it with other vessels because no drilling is involved in the installation process. It uses a Deeper Arm Mount for kayak installation so that it remains flexible and versatile. In this mode, you can also create live GPS-powered maps. 

3. Boat Fishing

The Deeper Pro+ allows casting and trolling from a boat. This gives you a better range for scanning all the hard-to-reach areas. 

4. Ice Fishing

The Deeper Pro+ can detect fish even in ice. It is a fast way of knowing whether there’s fish in a particular area so that you do not need to drill before you know it’s the right spot. And if a certain spot has lots of fish, you can map it out and never waste time searching for it again.

Battery Life

A rechargeable Lithium-Polymer 850mAh battery powers the Sonar Pro+. It arrives uncharged, so you have to charge it the first time you use it. It is supplied with a USB cable which you can connect to a computer port or your car’s power outlet. 

When GPS is not activated, the Deeper Sonar Pro+ has six hours of battery life when used in the 290kHz frequency. In the 90kHz frequency, you get 5½ hours or running time. With GPS the running time is reduced by 30 minutes on the 290kHz frequency and by one hour on the 90kHz frequency. 


Can Deeper Sonar Pro+ record video?

This device transmits sonar information directly to your device. Like when you are scanning the area you want to fish, it will give you data to work with, and you can save in on your device to watch later. 

Does Deeper Sonar Pro+ float?

Deeper Smart Sonar Pro is designed to float on water. It is waterproof to a depth of one meter. In the submerged state, this device will record for five minutes and transmit the information when it resurfaces.

Can Deeper Smart Sonar Pro+ be Used While Trolling on a Kayak?

Yes, It is distinctive transportable, easy to cast functionality makes the Deeper PRO+ comfortable to use by kayakers all year round. Fish are always waiting to be found, so use it at any time to improve your catch rate.

What's the difference between Deeper Start vs. Deeper Pro vs. Deeper Pro+ fish finders?

Deeper Start is designed for shore anglers. It casts a powerful 40-degree sonar and has 130ft connection range over Wi-Fi. It can scan to a depth of 165ft. 

The Deeper Sonar Pro+ sends scans automatically to the Deeper app. All the data is synced with a cloud server so that you can access it later. All your scans can be accessible from anywhere when you want to analyze your fishing history. 

The Deeper Pro is much like the Pro+ except it is not designed for onshore GPS mapping. It is much cheaper than the Pro+, and it has all the other incredible features of Deeper Pro+.

You’d like to purchase a Deeper Sonar but aren’t sure which one is the best for you? Let’s take a look at the specifications, display, features, and hardware of the Deeper Smart Sonar PRO+ & the Deeper Smart Sonar CHIRP to help you decide.

The Deeper PRO+ has both a basic and detailed App display mode. With modifiable sensitivity and a selection of three color palettes, it displays bottom stability, depth alarms, topwater temperature & underwater vegetation.

The Deeper CHIRP offers a more detailed display and can highlight baitfish, predator fish, structures & vegetation. It can distinguish between the bottom contour as well as recognize bottom stability, water depth & temperature.

Both Deeper Sonars can create bathymetric maps whilst out on the water, but only the Deeper PRO+ can create bathymetric maps from shore. When it comes to capability, know that both Deeper Sonars have a casting range of 330ft / 100m, but only the Deeper CHIRP has a fast charge function. The Deeper CHIRP has a minimum scanning depth of 6” to 330ft / 15cm to 100cm. By contrast, the Deeper PRO+ scans a shorter distance from 19” to 260ft / 50cm to 80cm.

Another important aspect is that The Deeper CHIRP sonar beams can reach three angles (47°, 16°, and 7°), though the Deeper PRO+ has a dual beam (a broad 55° & narrow 15°).

You use any type of boat, ice and they are equally as good for night and shore fishing. Before you head out to buy though, take note that only the Deeper PRO+ is equipped with a built-in GPS. This helps you to create bathymetric maps from the shore.

The Deeper CHIRP has a target separation of 0.4” and the Deeper PRO+ can separate targets at 1”. The latter impresses by being the only one able to detect water temperature. Both Deeper Sonars can be used in either fresh or saltwater and either model will operate in temperatures between -4°F to 104°F.

The CHIRP is the lighter of the two, weighing in at 3.2oz. Slightly heavier, the Deeper PRO+ has a weight of 3.5oz. The CHIRP is also the pricier option. If it’s fancy tech you’re after, both Deeper Sonars function via Wi-Fi.

The Deeper CHIRP is recommended for both advanced and expert anglers who will benefit from its depth precision, flexible three-beam scanning frequencies & exceptional target separation. An ideal option if you regularly cast or troll from a kayak, small boat or SUP. It’s is also an excellent selection if you enjoy ice and shore fishing.

If you’re searching for absolute changeability, maximum power, and brilliant water body mapping from a boat, ice, kayak or shore, the Deeper PRO+ is the one for you. It’s used by a variety of skilled, expert and amateur anglers.

What Do the Deeper Smart Sonar Pro+ Users Say?

Customers have shared that the Deeper PRO+ functions very well. It is both simple and straightforward to use. It is functional for ice, kayak, pier and shore fishing. With the benefit of discovering what lies beneath small lakes, its quick scanning capability leads to purposeful angling.

The Wi-Fi functionality and accuracy make it easy to find fish fast. The depth scanning and fish locating feature can help you to better understand the patterns of your target fish, particularly in different seasons.

It’s important to cast the Deeper PRO+ out carefully into deep water and then slowly reel it back into the shallow water. Always consider hidden logs, rocks or other obstacles that could harm the electronic sensor.

While the lithium metal battery is rechargeable, the battery usually needs to be replaced approximately every year, like most other gadgets. Finding a replacement battery locally can be a challenge. Take into account that you will most likely have to pay for both repairs and shipping of the battery from Europe to ensure you can keep on finding those fish.

The onshore GPS option for creating bathymetric maps can prove extremely beneficial when plotting a pond or lake to store the information for future reference. Fishermen who live in areas with access to many bodies of water, find this feature advantageous to help locate the best fishing spots and continue tracking down that perfect catch.
