iBobber versus Deeper Pro versus Fish Hunter Pro Review

Modernization has placed the old rod and reel fishing instinct in the corner and introduced the portable fish finder technology. Fish finders are effective tools that allow you to locate fish underwater. This technology works using the SONAR (sound navigation and ranging) technology system.

This portable tool shows a fish’s location in a digital screen, which can be either an LCD or a CRT type. The technology of the fish finder has constantly been upgraded since the 1990s. Today, it is one of the most sophisticated devices as other features have been integrated. Helpful tools such as the GPS, electronic compass, and radar have now been incorporated.

Here is how a fish finder works: A transmitter, which is found on the ship, sends signals in the waves. The SONAR system utilizes the aspect of echoes to reflect back the waves to the transmitter. These reflected waves are recorded. And then, a signal will be sent to your screen.

As they say, there are plenty of fish in the sea. The question is what the best fish finder device there is is. Today, we will take a deeper look into the fish finders from iBobber, Deeper Pro, and Fish Hunter Pro.


iBobber Smart Fish Finder

The iBobber was designed with portability and flexibility in mind. It is an excellent choice for those who are hunting for an affordable, portable, and user-friendly fish finder.

Fish Hunter Pro

The Fish Hunter Pro is a wide-ranging underwater scanning device that will help you look for big schools of fish. This sonar device floats on the water. It can easily be cast, trolled, or placed in your ice hole where it can detect and record relevant data including temperature, depth, fish spots, and bottom contour. It gives a “ping” sound if it detects any disturbances in the water.


  • Offers two views. The RAW view gives you the actual results from the transducer. You can see the sonar feedback in a plain, traditional sonar view. On the other hand, the FISH view collects the RAW sonar data and reconfigures them on the app. Fish are drawn in a water column, so it is simpler to view.
  • Uses dual beam sonar of 475 kHz and 675 kHz
  • Utilizes a high-quality Tri Frequency Transducer. This can work on different frequencies ranging between 381 kHz, 475 kHz, and 675 kHz. This also allows you to go near the CHIRP sonar for a high definition sonar feedback. Both shallow and deep water readings are also possible.

Comparison of iBobber Smart Fish Finder, Deeper Smart Sonar Pro, and Fish Hunter Pro


Depth and Casting Range

The fish finder from Deeper scans deeper and cast further compared with the iBobber. The Deeper cast up to 330 feet, which is three times further than iBobber’s capability. It can also scan down to 260 feet, enabling you to detect the most productive fishing zones. iBobber can only do up to 135 feet. That being said, the iBobber will work fine on small bodies of water. Lastly, the FishHunter Pro can reach a depth of up to 150 feet for ice fishing and 100 feet for jig tracking, with four times faster display action. It can scan a width beam of 160 feet.


Marking Fish

Both the iBobber and Deeper are capable of marking fish. The iBobber only has one sonar frequency at 118 kHz (42o cone). Such a wide beam allows you to look at the fish’s general area only, but not the specific location. Moreover, the deeper you go, the harder it will be to pinpoint the fish’s exact spot.

Meanwhile, the Deeper is equipped with both wide and narrow beam scanning at 90 kHz (55o cone) and 290 kHz (15o cone), respectively. You can use the wide beam to scan the area first and then switch to narrow to lock a target.

The FishFinder Pro provides a more detailed feedback. It boasts of a Tri-Frequency transducer too that work on three different frequencies. It can be set at 381 kHz, 475 kHz, and 675 kHz. A higher frequency will give you the most accurate readings. However, it does not work well on deeper water as you will need a lower frequency to see the picture clearly. Take note though that it needs to be placed in at least 4 feet of water to function. Using the RAW view, fish are identified as ‘arches’ of color in the water column or near the bottom.


Ice Fishing

The iBobber is not created for ice fishing. But technically speaking, it can operate in below freezing temperatures. However, it will have a hard time. First, remember that this only uses a wide beam scanning frequency. It might only work on a very thin ice surface. Second, it has a low frequency so it will be difficult to pick up signals. Lastly, it has no ice fishing setting so it will be impossible to zoom in or track your lure.

Meanwhile, ice fishing is one of Deeper’s forte. As mentioned earlier, it both has a wide and narrow beam scanning frequency. The wide beam can be used even on small lures and jigs, while the narrow in ice holes. The app features an ice fishing mode and a GPS Ice Hole marking. The latter allows you to save data on every ice hole you fish.

The FishHunter Pro has been designed as an ice fishing flasher. The device is made for ice as it can withstand extremely low weather conditions as low as – 30oC (-22oF). The Ice Fishing Fisher View makes use of two ultra-high frequencies 475 kHz and 675 kHz. This can let you see your jig in real time. The Split Screen (Flasher/ RAW Data) and Full Screen (Raw Data only) allows you to check the bottom, the bottom depth, and the temperature straight to your mobile device.


Continuous Scanning Time and Battery Life

The iBobber has longer continuous scanning time as it utilizes low-frequency sonars. The device can last up to 10 hours of scanning. Meanwhile, the Deeper Pro uses dual frequency sonars and scans 15 times per second. While it has better accuracy, it only lasts within 6 hours. The FishHunter Pro is a wide-ranging underwater scanning device. Its scan range can reach up to 160 feet.

Long battery life is one of the holy grails in any devices. The iBobber does a pretty good job, giving anglers up to 10 plus hours of battery life. The battery is rechargeable, and it comes with an indicator light for your charge status.

The Deeper Smart Sonar Pro can last up to 5.5 hours of usage. It will take 2 hours to recharge the battery. The device can also remain for up to 6 months in sleep mode without charging. It is important to note that very cold temperatures can quickly drain a battery’s life.

Meanwhile, the FishHunter Pro is packed with a rechargeable Lithium Polymer battery that can last up to 10 hours. When put on standby, battery life lasts up to 500 hours.


Factors to Consider in Choosing a Fish Finder

There are several factors you need to consider before purchasing your own fish finder. The most important one probably is that it should successfully locate the kind of fish you are hunting for. Ease of use, durability, and reliability are also included. But most fishermen are very specific. Other than the comparisons mentioned above, here are the things fishermen look at and compare.


  • Transducers—These are an important part that sends and receives sonar signals underwater. You should also consider the frequency at which a transducer
  • Cone Angle—This represents how wide of a “net” the signal will cast after it has been deploWyed into the water. Cone angles usually range between 15o and 20 o. Some use multiple cones.
  • Display screen—Most recent fish finders now flaunt full-color screens. Colored ones have a bigger advantage as details are much clearer. The lowest recommended screen resolution is 240 x 160. Taking those numbers up would really be beneficial.
  • GPS capabilities—Nothing is more convenient than having a fish finder and GPS all in one device.



Overall, fish finders are not a “one size fits all” device. We all have different necessities. We vary on what we look for on any devices. Whether you want to fish on the water or shore during hot or cold weather, there is always something for you. So labeling a certain fish finder as the “best” appears like disregarding other people’s needs.

All three devices have their own strengths and weaknesses. They are suitable for people from the beginner to pro in the fishing field. A piece of advice, get something that will provide you with your need. Extra features can get confusing and frustrating for some anglers. Just study each one closely and pick the one that will give the results you demand.

We hope that you find this review helpful. We hope you will have a great fishing time.
