Deeper Fish Finder Review: Easy Location of Where the Bites Are

Want to know where the best spot is to fish in deep water? Our Deeper Fish Finder review can help you learn about the products that increase your chances of catching fish in the ocean

One of the toughest parts of fishing is knowing where to go to get the best bites. You can hover in the shallows, but that only gets you so far, not to mention fish will eventually become wise to your tactics and whatever bait you drop. You’ll need to take your fishing into deeper waters.

This, however, poses its problems. Depending on how deep the water is, you’ll have a hard time knowing where fish are. Water is often murky, and it can be difficult to see where fish might be or how they might respond to your attempts at luring them in. This is where a Deeper fish finder can help because you can know where fish are likely to hide.

What is a Deeper Fish Finder?

A Deeper fish finder is a device that sends sound waves through the water and provides a digital readout with graphics to show information about the bottom of the lake. You can then use this information to find out where the fish are concentrated.


You'll also be able to see information about bottom vegetation, structures, the temperature of the water, and other information that can help you find a potential catch.


Product Specifications

  • Connection: Wi-Fi, 2.4 GHz
  • Casting Range: 330 feet for Deeper Pro
  • Effective Scanning Depth: 260 for Pro
  • Angle for Scanning: 15 or 55 degrees for dual-beam scanning
  • Weight: 3.5 ounces

How Does a Deeper Fish Finder Work?

The product consists of two main parts and requires a smartphone to function. The central unit is a spherical device that can be set in the water, where it automatically turns on. As you cast the sphere into the lake, it sends out sonar pulses at the rate of about 15 per second. This gives you a solid image of how the underwater conditions are.


Of course, you can’t see data just from a device you place in the water. It creates a wireless Internet signal that it can broadcast to your smartphone, provided you are using the companion app for Deeper. Open the app, set the finder in the water, and connect to it. Note that for this Deeper fish finder review, we’re focusing on the Deeper Pro pack.

Deeper Pro Pack

No products found.

From what we can see, the Deeper Pro pack offers the best balance of the three packages in terms of the features and cost. Not only do you have the ability to test temperate waters, but you can also go to a wintery area and do some ice fishing. Unlike the starter pack, the Pro pack has a broader range of safe operating temperatures. 


It can withstand temperatures as low as -4 degrees Fahrenheit. The maximum is 104 degrees. Hopefully, you never have to fish in water at this temperature, but it has been tested to that rating. 


The Deeper Pro fish finder has two attachment points: one for your rod and another for the line itself so that you can cast. Some customers reported that the attachment bolt would not hold the unit securely, but it’s possible they cast too hard or too far. Exert no more force than you would normally.


Once the unit is in the water, it continuously will emit signals that take sonar readings of the bottom of the lake as well as any fish that are currently in the area. By accessing this information through the smartphone app, you can view a false-color reading that generates. It’s recommended that you get the smartphone rod mount.


Users reported that setting the phone down or pocketing it could disrupt the Wi-Fi signal easily. Also, the mount allows you to keep an eye on your phone in real time.

Pricing and Where to Buy

The price we saw, though subject to change, for the Deeper Fish Finder Pro, is approximately $​$- $​$ depending on the specific retailer. This price includes the sonar unit, the smartphone app, and other paraphernalia.


You can get the product on the Deeper website, but you can also go to other online retailers that sell fishing gear. Alternatively, you could go to a physical store that sells outdoor equipment, and they may have the Deeper fish finder suite.


Warranty

The Deeper Fish Finder Pro has a manufacturer's warranty that is good for one year. It is a limited warranty, meaning it only covers defects in workmanship, but not user-related wear and tear or improper use.

How it Compares


No products found.

Now we’ll take a look at some other brands and see how they compare to the Deeper model. We look at the ease of use, the overall quality, and the versatility to determine which is ultimately the best value for this Deeper Fish Finder review.

Dragonfly 4Pro

No products found.

The Dragonfly 4PRO by Raymarine is a unit that mounts on your boat and sends signals to the bottom of the lake, just as the Deeper unit does. While it provides the same functionality as the Deeper unit, it doesn’t allow you to attach a floatable unit to the rod for casting. In other words, if you want to know what the bottom of a lake looks like, you have to move your boat over it.


The Deeper unit is also more portable. Unlike traditional boat sonar units like Dragonfly, it can fit right in your tackle box. The downside is that the electronics are far more fragile because the floating unit can hit an underwater rock or something similar.


One advantage the Dragonfly has over the Deeper is a more extended warranty. Where the Deeper has only a 1-year limited warranty, this one has a 2-year limited warranty. If you register it online, you can make it a 3-year policy.

Lowrance Fish Hunter 3D

No products found.

The Lowrance Fish Hunter 3D wireless transducer fish finder is a similar product to the Deeper fish finder. Its price range hovers around the $​$ mark, based on the retailers we looked at. The Lowrance has a similar ball design that you can attach directly to your fishing line, making it a great competitor.


One thing we noticed immediately about the Lowrance model is that it was heavier. It weighs in at about six ounces. While you can cast it from your rod, we'd recommend you use a heavier line and a stronger rod to do so. Otherwise, it might break the line.


So where does the extra weight come from? It turns out that the Lowrance fish finder can provide up to five different sonar mode displays streamed right to your smartphone. The Deeper Pro provides up to three. If you had the highest-end Deeper model, its capabilities would be the same.


It has more functionality than the Deeper, but it is heavier, and you’ll need to have a stronger line to hold it. Also, the Lowrance model, from what we could determine from our research, has longer battery life. Some users reported the Lowrance Fish Finder to have a 10-hour battery life, compared to the Deeper’s 5 hours of continuous operation.


One area in which the Deeper Fish Finder Pro has over the Lowrance is the scanning range. Where the Deeper has a 330-foot casting range and a 265-foot depth range, the Lowrance only goes down to about 165 feet. While this may not mean much if you stick to the shallows, we’re all about going into deeper waters. Therefore, we give the advantage here to the Deeper.


The Lowrance model has a limited warranty, but you have to purchase it separately, and it varies by retailer.

ReelSonar iBobber

No products found.

The ReelSonar iBobber is by far the most lightweight product on our list. Weighing in at only 1.5 ounces compared to the 3 and 6 of other products, this one might come off as a bit fragile compared to its competitors. However, it has much of the same usefulness at an even lower price. This model costs around $$, compared to the $​$ prices elsewhere.


Looking at the performance specs, it doesn’t seem like the ReelSonar scans to the deepest parts of lakes. Its scanning depth reaches only 165 feet, compared to the Deeper’s 265-foot scanning depth. The ReelSonar has a less powerful sonar unit equipped, but it still does the same things.


However, this isn’t to say that the ReelSonar is without its advantages. For example, it has a strike alarm built in that will give you a discreet alert sound should there be any fish near your hook. At that point, prepare to set the hook, because you might be getting a bite.


Also, it has an LED for nighttime fishing. While you can buy an orange fishing cover or the Deeper fish finder, it’s an aftermarket choice, whereas the ReelSonar has it equipped by default.


For its lower price point, it serves its function well enough, and it seems to have a few bells and whistles that its higher-priced competitors don’t have.

​What We Think


Based on what we’ve read about several different fish finders for this Deeper Fish Finder review, we think that the Deeper Pro model will provide you with the best value for your money. Other products might edge it out in specific categories, but the Deeper has the best all-around performance.

Ultimately all of the products are the same concept: a sonar transducer inside a floating ball that can then send the signal to your wireless phone. They differ in their range and what they can do. Some of the Deeper product peripherals you’ll have to buy elsewhere, but most of what you need comes right out of the box.

Deeper Fish Finder Review: Final Thoughts

Fish finding technology is still relatively new, at least as it relates to finding fish. The idea of sonar often occurs in nature, such as with dolphins and bats. You might need to pick between a wireless transducer and a boat-mounted one. If you do choose a wireless fish finder such as the ones we’ve listed today, you’ll need to keep your phone’s connection on low usage.

Another feature many of these products have is the ability to store and upload maps. Lake conditions are often updated month by month, so you don’t have to worry about hitting a sandbar. These products are meant for both fresh and salt water. Not many people, however, would take to the ocean to fish for a casual trip, unless they lived nearby already.
