The Best Portable Fish Finder Review

The Best Portable Fish Finder Review

Portable fish finders are a great choice for every angler who wants to have the freedom to choose their fishing spot.

They can reach places regular fish finders can’t. You can temporarily mount them on a boat, use them when fishing from the shore, and take them with you wherever you go.

If you’re looking for a portable fish finder, you have to consider the type and the features each model has. This review guide will show you the types of portable fish finders and the top 5 models to help you choose the best portable fish finder for you.

Types of Portable Fish Finders

There are three types of portable fish finders:

Portable Units

These are the classic portable fish finders. They consist of a nylon case that carries the unit’s elements, including:

  • A small fish finder unit with a 3-7 inch screen
  • Portable transducer
  • Plastic mounting base
  • 12V battery

They are best used on small boats but can be also used for ice fishing and open water fishing.


These fish finders are perfect for temporary mounting on small boats. They are also the only type of portable fish finders that work with a float tube.

Smartphone (Castable)

These are the latest generation of portable fish finders. Unlike traditional fish finders, they consist of a small floating transducer that connects to the app on your smartphone via Wi-Fi or Bluetooth to display the scans. They are best used for bank fishing but can also be used on boats.
