Best Portable Fish Finder – Buyer Guide and Reviews

best portable fish finders

A well-made portable fish finder has a lot to do with a successful fishing trip.

Whatever the conditions, a portable fish finder can help reveal precisely where the fish are hiding.

Consequently, you will know exactly where you should cast your line.

There is a lot to consider in choosing one. You would have to determine what kind of marine environment you would be using it in.

You would also have to consider its suitability to that environment, of how well it can direct you to your targeted catch.

There are many products that claim to be perfect for the job. Inevitably, however, some will fall short of the gold standard and few products will remain as the best fish finders you can buy.

The reviews we have listed here are not likely to disappoint.

They have been picked on a simple price-relative-to-performance basis.

They are also some of the best fishing devices currently available on the market.

What Are The Best Portable Fish Finders 2018

Here they are featured in the table below.

How To Choose The Best Portable Fish Finder

Being quite an essential tool of fishing these days, it is crucial for anglers to choose correctly with fish finders.

There is a lot of variety in the market and selecting one is not that easy. There are numerous features and applications to consider.

Happily, however, there are some fundamental criteria that should whittle them down considerably and make life easier.

Types Of Fish Finders

Portable fish finders come in three main categories.

There are versions that feature GPS tracking. These are ideal for anglers fishing out at sea and would need some direction with getting back to shore. They can remember prime fishing spots that have been visited before. They also have sonar which can paint a clearer picture of everything under water.

Then there is the standalone version. It also has sonar but no GPS tracking. Sometimes, however, these services may be offered for an additional fee. It is the best fish finding device for kayak fishing. This is mainly thanks to its sonar, able to deliver accurate readings of depth and temperature.

Finally, there are the fish finders with networking features. They are certainly not cheap. However, they will allow you to locate different hotspots or share pictures online.

The Transducer

The transducer is the part of the device that produces sound waves that generate images.

The key feature to look for with the transducer is the cone angle which is to say the beam width.

The more width there is, the more area that will be made visible to you. The angles of cones are commonly between 16 and 20 degrees but can vary from 9 to 60 degrees.

Other features to consider with the transducer are its frequency capacity and the kind of beam it emits.

Low frequencies are suited for deep water while higher frequencies are good for the shallows. For anglers who fish once every so often a single beam in their transducer is sufficient.

Any more than that would be more expensive but would also better your chances of landing the big game.

How Powerful Is The Portable Fish Finder

Power is a particularly important aspect of a good fish finder.

In very simple terms, the fish finder recovers information via the sonar emitted from the transducer. The more power your fish finder can generate, the faster its readings can be displayed.

Devices with a relatively low power output are best suited for shallow water.

These are some of the crucial equations to remember: 50kHz for each 100-watt output has a range of 400 feet. 200 kHz per 100 watts carries a range of 100 feet.

Screen Size and Resolution

Whatever your pick, it is best to go with as large a screen as you can pay for.

And make sure it can be seen clearly in direct sunlight as well as in low light.

A good benchmark for screen resolution should be 240×160 pixels.

This way, it will be easy to note what is on the screen while you are occupied with something else. After all, a portable fish finder needs to be as practical and efficient as possible to make a good fishing trip.

Colour screens are now becoming the norm with fish finders.

Their displays usually carry more detailed images can identify objects for anglers a lot easier than the black and white screens.

They are also a lot easier to read in appalling weather and in bright sunlight. That said, the more traditional black and white screens are still commercially available.

However, chances are you could do better with a color display on your new fish finder.


There are some delightful features in this area that may not be mandatory but still great to work with.

For instance, pre-installed maps of major waterways in a particular region or country, or an HD layout of the terrain underwater. Both these features would make fishing in unfamiliar areas a lot easier.

Other useful extras include a protective casing, suction mounts and easy ways of programming the device to find what you want.

After carefully considering the aforementioned criteria, you should be able to make a well-informed decision on your portable fish finder.

Portable Fish Finder Reviews

Deeper Smart Sonar PRO+

The Deeper Smart Sonar PRO+ is a portable smart fish finder having its own Wi-Fi feature that can be accessed by your android or IOS device.

It is ideal for all kinds of fishing in both freshwater and saltwater as it carries the only portable sonar on the market with GPS enabled onshore bathymetric mapping.

At 330 feet, the PRO+ also has the longest range of any commercially available sonar.

The device can detect anything as tiny as half an inch in up to 260 feet of water and is capable of delivering real time information of depth, water temperature, the location of fish species and underwater vegetation.

As you would expect, the cutting edge technology of this fish finder is extremely beneficial to customers.

While there has long been an element of mystery for anglers about just what exactly goes on below the surface, with the Sonar PRO+, that need no longer be the case.

What makes it even better is that it is well suited to so many different kinds of fishing – shore fishing, river fishing, ice fishing, kayak fishing, float tube fishing – the lot!

The main drawback is the connection to your phone is likely to sap quite a lot of the battery so your fishing trip could come to an abrupt halt.

And if you take it to a remote enough location, you may encounter trouble with the Wi-Fi connection.

The Garmin Striker is an impressive fish finder, particularly for those who have tested it out in winter.

Much of its critical acclaim has been about its simplicity, how it is all ready for the boat after coming straight out of the box. Its mechanism for locating places has not disappointed so far.

That said, there have been some issues with the transducer and flasher.

Maintaining a horizontal position on the transducer on the bottom has proven to be tricky for some.

The flasher, on the other hand, has been criticized for being unable to pick up an angler’s jigs.
