Traditional portable models :-

These are the most common models one can find in the market, and many brands offer these types due to high demand. Although all of these models are lightweight, the size of them is relatively larger in hands.

These operate by sending the readings to the screen connected to the device wired or wirelessly. You can use the screen that comes with the device to play with the settings or to control the unit. If it is not a touch screen, dedicated buttons are provided for control.

Such portable units are reliable and can provide accurate readings with an efficient transducer. With decent battery life, these devices have a user-friendly interface to read graphs easily.  Carrying these devices is not a problem as most of such models can easily fit into a bag.

Castable model :-

Castable models of Portable Fish Finders are the modern version of the traditional units. These devices use Bluetooth or Wi-Fi to connect to smartphones or tablets. You can easily catch the transducer in your hands as they are compact and reliable at the same time.

Besides being portable, these models are also efficient in data transfer. All you have to do is install a dedicated app from the manufacturer, and you can use your phone as the real-time screen. You can analyze the readings, send multiple frequencies, mark waypoints, and map as well.

Hybrid models :-

With the rapid development of technology, marine electronics also developed to a great extent. Thus, many brands are also offering these hybrid models, which possess all intriguing features in one device. Such devices are probably the smart option in Fish Finders for all fishing scenarios. However, with the infusion of many features, there may be compromises on battery life and accuracy. Thus one should follow the factors provided below as well.

Quality of the Transducer :-

The type and quality of the transducer is the topmost priority once you have decided on the kind of portable fish finder.  The transducer serves the vital role of a Fish Finder in finding the water’s best fishing spots. If you end up getting a device with a high-quality transducer, your primary purpose is all set.

install transducer correctly

The transducer is what emits different frequencies to the water and sends the bounced back signals after configuration and adjustments. If you want to be assured of accurate readings from the transducer, you should look for customer reviews. Now that you have the top 8 best fish finders, accuracy is not a matter of worry anymore. 

You should prefer the model with high wattage for higher depths. However, a powerful unit is essential for depth fishing, and power ratings should never be compromised. Also If you don’t know about How to Install a Fish Finder Transducer, must follow it will help you.

Battery life :-

Battery life is a crucial factor for portable fish finders as almost all of them are wireless even when you choose the hybrid model. Your fishing trip can turn disastrous if the battery of your device runs out in the middle. Thus, it is quite essential to look for good battery life while preferring a portable fish finder.


Most portable units at present last from 8 to 10 hours, but there are some models with less battery life. Make sure such devices have a dedicated battery level indicator and battery saving modes as well. These advanced modes reduce the burden on the battery and extend the battery run time. Even if your chosen model has 10 hours of battery life, an indicator is indeed favorable from all aspects. 

Display Quality:-

Display is the second most crucial factor that decides the portable fish finders’ quality. Being portable, the screen which comes along with the device is going to be small for sure. Thus, make sure that it is a colored display with proper differentiation for different factors.

Vertical displays with dedicated physical buttons for control limits the vision for readings and mappings. You can find the devices with a small yet efficient display that can deliver complete information at a time. Even black & white displays are capable of showing most of the information and simplify the mapping.

Raymarine Display

The devices listed above possess a minimum screen size of 3.5 inches but can contain all information.  However, the colored display is user-friendly and can easily differentiate the structure, edges, contours, and maps.

Connectivity :-

Almost all portable models of Fish Finders are wireless, which is why connectivity plays a significant role. Make sure that the connectivity is reliable whether the device connects to the screen or any other device.  

However, Wi-Fi connectivity via application is always best. In such models, wireless connectivity is pretty reliable, and you can see the distance as well. The device sends sonar data to locate the fish using wireless connectivity, which is crucial for fishing. With the data connection, you can also easily share the data with your friends or social media.

Cone Angle:-

Transducer of the Fish Finder emits a cone-shaped beam. These can be of different frequencies but also vary in the angle of the cone as well. As the angle increases, the area covered by the device also increases. Thus, you should choose the device with the cone angle best for your requirements.

Wide cone angles are meant for shallow water fishing or ice fishing, as these fish finders can cover large areas. Well, with the increase in area, the quality of the image decreases too.

On the other hand, if you are more into deep fishing, you should prefer the devices with narrow cone angles. These beams can go deeper inside the water and can grab useful details below the water surface.

Waterproof: –

Waterproof Fish Finder

No matter which type of Fish Finder you need, being waterproof is the essential quality of such devices. Search for proper IP-rated certification to ensure it safe to use on your boat, kayaks, or off-shore. However, casting models are probably as waterproof as they need to be half-immersed in the water for readings.

Cost: –

Last but not least, make sure that you are grabbing one of the best possible deals with no compromises in the features. There can be a few compromises on the cheaper models, but you should consider all the factors as mentioned earlier. Portable models are available within the price bracket of $50 to $350. Thus, just go to the specs on paper and compare the pros & cons to get the best price for the most favorable product.

Q1. Are portable fish finders better than normal ones?

It depends on your requirements and whether you need the applications endorsed by portable fish finders. For instance, if you require a Fish Finder to carry anywhere and put it on work on-the-go, portable ones are better choices.

You can mount it literally anywhere using the clamps provided in the package and adjust them as you need. Besides, there are a lot more applications in fishing with portable units. Castable models of fish finders are efficient in ice fishing with reliable wireless connectivity. 

Q2. Can I rely on the wireless connectivity of Portable units?

Yes, you can rely on all the devices mentioned above in terms of wireless connectivity. But, if you are looking for a portable Fish Finder with seamless connectivity, choose the one with dedicated software. 

For instance, Lowrance features best-in-class technology with its Fish Hunter device. The Fish Hunter App is probably the most reliable software with a user-friendly interface. However, make sure to go through the spec list and find the device with more connectivity range before choosing a device.

Q3. Is battery life important for portable fish finders?

Definitely, being battery-powered and being wireless means you should definitely give battery life the topmost priority. It is probably safe to buy a portable fish finder with more than 8 hours of battery life. 

You can also choose the device based on the charging speed with some compromise on battery life. But, the smart option would be selecting a device with a proper battery indicator. Even if your device has 4 to 5 hours of battery life, you can be assured of the run time while fishing.

Q4. Should I prefer a separate screen or connectivity with different devices?

Both options are great, but a portable fish finder comes with a small screen with limited options.

You can’t split the screen in dedicated screens due to vertical screens with 3.5 to 5 inches. Thus, connectivity via App to Smartphone or Tablets is excellent as you can do everything at your ease.

Even the display will be quite favorable in both daylight and dark environments with smartphones. However, the screen’s connectivity is much faster than the connectivity with other devices in some Fish Finders.

Q5. Shall I prefer a color screen or black & white screen in Fish Finders?

Both screens have different advantages and drawbacks. The colored screen gives a crisp and clear image in which you can easily differentiate other objects apart from fishes. It is also very useful in mapping or noting the waypoints. But, the only drawback is a colored screen drains the battery faster than black & white screens.

On the other hand, black and white displays can detail the screen with different shapes. It is relatively easy to identify various structures but has limitations in detections. Nonetheless, battery draining is much less when compared to the colored screen.
