What Are Portable Fish Finders Particularly Suitable For?

A portable fish finder is something you may have to look into if you are on a kayak, boat rental or small boat.


You will certainly have a shortage of space if fishing on a kayak. All of the equipment will already be weighing down the kayak and any extra weight, however small, will make it more difficult to paddle. You will be forced to work harder and as such, you’ll be more tired at the end of the day. A portable fish finder is a compact and lightweight and will allow you to enjoy your fishing trip without adding too much weight to your gear.

Rental boat

You will want to have a portable fish finder if you intend to rent a boat. The last thing you should do is permanently install a finder on a boat that you don’t own. It will just be a waste of your money.

Small boats

They suffer from the same issue as kayaks. While you won’t notice the difference as much when you add an engine and a few people, a portable fish finder can still prove advantageous on a small boat.

Types of Portable Fish Finders

There are three main types of portable fish finders i.e. mountable, portable and castable units.

Portable units are the traditional style of portable fish finders and usually include a nylon carry case that holds all of the components i.e. portable transducer, small rechargeable 12V battery, small fish finder and a plastic mounting base. These units are good for ice fishing and open water fishing and work best when used in small boats or kayaks.

Mountable fish finders can be temporarily mounted to the transom or side of a boat. They are the only type of portable fish finders that can be used with a float tube. Castable units are the new generation of fish finders. They feature a small floating transducer and communicate with an app on your smartphone via Bluetooth. Castable fish finders are best for bank fishing, but can also be adapted to boat or kayak use.

Criteria for Choosing a Portable Fish Finder

Now that you know when to use a portable fish finder and the different types available, it is time to explore other criteria for choosing a model that best suits your fishing needs. There are plenty of features to look for choosing a fish finder. But when it comes to portable units, below are the special things to think about.


One of the most important things is to make sure that your portable fish finder is easy to attach and detach without major damage to the boat. There won’t be a way to permanently install the finder on a kayak, and this can prove a problem for some anglers. There are some quick release options you can purchase, but that’s not the limit of your choices. Plenty of companies have found easier ways to detach portable finders.


Greater wattage offers clear and deeper readings more quickly. Go for a unit with the highest power you can afford, especially if you plan on fishing in deep waters. A minimum of 50 kHz for 100 watts of power will scan depths of up to 400 feet.


Dual sonar systems allow you to see near and far areas at varying detail levels. Higher frequencies provide more detailed information and are good for deep water fishing. In addition to frequency, you’ll also need to look at the angle of the sonar. There are options up to 120 degrees that give you a wide field of view. Make your decision depending on how deep the water you are fishing in.


Regardless of what your needs are, the 10 portable fish finders reviewed above are the best you will find. They are easily the most interesting gadgets for anglers, and their ease of use is something you won’t get with traditional fish finders. There are plenty of options out there and we hope you now have a better understanding of them to make the right choice.
