Deeper Smart Sonar PRO+ Review Facts

Sonar technology is an advancement in technology offered to fisherman in order to enhance their skill. Sonar allows fishermen to rely less on nets and bait, and focus more on the areas of higher population in order to get the most out of their day. Sonar sends off sound waves in order to hit the fish shoal and reflects back to the device monitoring the waves. This allows the fishermen to easily see the fish on the screen of the monitoring device. This also allows the fisherman to see if there are higher chances of catching fish based on the number of fish below the boat or ice. Sonar devices are often used in fishing competitions in order to assist the competitor to know which areas they should be spending time in and which are probably a waste of valuable time. The waves are typically emitted both vertically and horizontally. The horizontal waves emit in a circle in order to offer a circle around the boat or ice. The vertical waves emit waves deep into the water in order to show the fishermen what is deeper below the surface of the water. Several sonar fish detectors will also identify what is sea or lake life and what is junk like weeds or trash. This particularly helps the fishermen understand what is below them. Fishing with sonar makes sense as it helps with time management and will send the fisherman or woman home with more fish than traditional baits and nets.

It can be used for different types of fishing activities including shore fishing, kayak fishing, boat fishing, and ice fishing. As previously mentioned, this device can be used anywhere from minus 20 to plus 40 which is minus 4 to 104 degrees Fahrenheit. The device also reads in both Celsius and Fahrenheit for personal preference. The device can either be dropped in the water, cast into the water or positioned under a boat depending on the activity. The device connects to your handheld device and sends signals to it in order to assist in the users fishing trip. It allows the user to mark areas of interest, for instance, when regularly seeing higher fish populations in a particular area or when needing to record the dock for an easier return on bigger lakes. The device helps fisherman find ideal fishing areas while also indicating when the items under the boat are fish or if it is just vegetation or debris.


This device connects to the handheld unit as well as tablets. This is done through Wi-Fi. This allows the user to record data through their phone as well. This also helps with software updating as well as the reception. The device has lakes pre-downloaded but also allows the creation of maps through the device itself for ease of use. Those who bought this product were impressed with how easily they were able to connect the device to their phone as well as how easily the device stays connected to the handheld unit. This device has a connection range of 330 feet or 100 meters. It can connect to either iOS (Apple) or Andriod. It also offers an L1 48 channel GPS receiver and offers high 3m@50% accuracy. The sonar device itself offers up to 15 scans per second in order to offer a more accurate and real-time view of the items below the surface of the water and offers a depth range of up to 260 feet. It also offers dual beam frequencies and 290 kHz/ 90 kHz frequencies. This device offers good and reliable connectivity which is positive and saves from frustrations down the road.


This device uses a battery in order to power itself. The battery is an internal lithium polymer battery. It is completely rechargeable at 850 mAh. The device also comes with a charging cable in order to charge the battery. Those who used this device were happy with the battery life and also noted that the battery charged quickly. This is convenient for those on overnight fishing trips. Some did find that in particularly colder days that the battery didn't last as long as on nicer days which does seem plausible. This is also common with cell phones. One issue that some found is that the battery cannot be replaced on its own but rather requires sending back to the manufacturer to do so. Some also had some issues with the customer service team at Deeper as well. This can be a problem later down the road when battery replacement is required. Other than those issues the battery seems to be good. It lasts long both between charges as well as over its lifetime and it quickly charges which is positive.


This who used this device found it quite accurate and reliable, more information in the connectivity section.


This device offers superior connectivity which makes connection smooth and easy. The app offers an easy on the eyes coloring system as well which is convenient and simple. The screen also offers different color options in order to make use a little easier. The device itself is also quite sensitive so it picks up a lot more. Plus with the signal every 15 seconds, it's like having real-time viewing in clear waters. Those who used this device said that it is super user-friendly and easy to use. Though there were some minor issues in shallow water (2 feet or less) and it might drain the battery if using in that area. It is smart not to start using the device until in deeper waters. There were also some complaints about using this device in higher current areas but this is common with this type of device. Outside of these minor issues, this device is quite easy to set up, connects well and offers a ton of details in order to offer the best fishing experience which is great.


This product does not have a display as it connects to either a phone or tablet but the app itself does offer unique display features in order to offer ease of use. The app offers solunar forecasting which forecasts the weather and shows the fisherman the perfect day for fishing. It also offers fish and depth alarms in order to make tracking easier and more customizable to the person using the device. It offers three different color palettes in order to offer a more customizable display view no matter the weather. Some find that looking at a screen in the sun is impossible. The color palettes of this app allow the user to see the screen easier, even in brighter weather conditions. Overall, the display of this app is handy and convenient.


This device is quite reasonably priced considering its versatility and reliability. One thing to consider, though, is that this device does not come with its own handheld device which means that a cell phone has to be used. This is particularly an issue when the phone being used does not have a good battery life. This would render this device useless. The price can also be considered questionable due to the fact that it is solely based on the sonar unit. That being said, this unit is quite reliable, it is easy to use and does seem to offer superior accuracy and connectivity which is positive. It does seem that this unit is worth the price which is positive.
