What are Fish Finders? How Do They Work?
A fish finder is a device that locates fish in the water. They are popular among boatmen and anglers as they utilize SONAR (Sound Navigation and Ranging) technology.
Fish finders are vital when fishing, both for professional anglers and those fishing for leisure.
A fish finder identifies and displays the position of fish on a digital screen, either LCD or a CRT type. Modern fish finders even use technology systems such as GPS, electronic compasses, and radar, making them a lot more dependable and accurate than those previously used.
A portable fish finder is special because it can go places that regular finders can’t. Portable fish finders are great for instances when you can’t mount a permanent unit on a boat.
Also, they are a wonderful solution for temporary mounting on the transom small boats and taking on impromptu fishing trips. You can even use mobile fish finders when fishing on land!
After reading our definitive guide of the best portable fish finders, you will be able to come to an informed decision on which style and model are best compatible with your fishing.

Choosing the Best Portable Fish Finder: An Ultimate Guide
Before hitting adding a fish finder to your shopping cart at random, there are a few things you have to consider first. This will make sure that the portable fish finder you buy matches all your needs.
Transducer Quality:
A high-quality transducer is a key to accurate readings. A transducer emits the sound waves (sonar) and lets you know the location of fish nearby. Poor transducers are essentially worthless.
We found the transducers for Garmin Striker 4cv GPS Fish-Finder with Transducer and the Humminbird PIRANHAMAX 410170-1 Portable Fish Finder to be in great shape.
Battery Life:
A fish finder with a weak battery life is no good. You don’t want your device dying an hour into your fishing trip. For this reason, you should go for something with a long and dependable battery life.
If you don’t mind plugging your device battery in while using it, we recommend getting the Garmin Striker 4 with Transducer [010-01550-00].
However, chargeable batteries, like the ones used with Garmin Striker 4 with Portable Kit or Deeper PRO+ Smart Sonar GPS Portable Wireless Fish Finder are more convenient.
Portability:
Not all portable devices are equal. Some can be a little heavier, like the Humminbird 410190-1 Fish-Finder System Helix 5 Series Sonar G2. Many people prefer the heft that these devices have.
On the other hand, if you want something very lightweight and easy to transport, you will prefer something like Deeper PRO+ Smart Sonar GPS Portable Wireless Fish Finder or the ReelSonar Wireless Bluetooth Smart Fish Finder.
Mode of Use:
Some devices like the Humminbird PIRANHAMAX 410170-1 Portable Fish Finder or the LUCKY Wired & Wireless Portable Fishing Sonar can be used in all conditions.
However, others work better in specific settings. For instance, smart devices are best for fishing on a vessel.
On the other hand, something like the MOOCOR Underwater Fishing Camera and Portable Fish Finder is best when fishing on land.

Fish finders work the same as they do underwater. However, you must take a couple of precautions. For example, you shouldn’t use it in extremely cold conditions.
