A permanent fish finder installation is not practical for everyone.
You may fish from a rental boat one weekend, a kayak the next weekend, and then go ice fishing or bank fishing later in the year.
Drilling holes, running cables, mounting a display, and permanently installing a transducer does not make much sense in that situation.
That is where portable fish finders are useful.
Some give you a normal dedicated fish finder display inside a carrying case, while others use a wireless sonar sensor and your smartphone.
I researched the current portable fish finders available through Amazon and selected options for several different types of fishing.

Best Portable Fish Finders
The first thing you need to decide is what “portable” means for you.
If you want traditional sonar without permanently mounting anything, a portable kit with its own display is probably best.
If you want something you can literally put inside your tackle bag, wireless sonar makes more sense.
For bank fishing specifically, you should also read our Best Castable Fish Finder for Bank Fishing guide because those units are designed to be thrown out using a fishing rod.
1. Best Overall Portable Fish Finder: Garmin STRIKER 4 Portable Bundle
The portable version of the Garmin STRIKER 4 is a great option if you still want a traditional fish finder screen.
You do not have to rely on your phone, Bluetooth connection, or Wi-Fi connection while fishing.
The STRIKER 4 uses CHIRP sonar and includes GPS, allowing you to mark waypoints and return to productive locations.
The portable kit makes it much easier to move between small boats, kayaks, canoes, and ice fishing setups.
Current Amazon-focused portable fish finder comparisons continue to rank the STRIKER 4 Portable Bundle as one of the strongest dedicated-display portable options.
Special features:
- Dedicated color display
- CHIRP sonar
- Built-in GPS
- Portable carrying setup
- Waypoint marking
- No smartphone required
2. Best Wireless Portable Fish Finder: Deeper PRO+ 2
The Deeper PRO+ 2 is much smaller because there is no dedicated screen.
Everything happens through your smartphone.
The sonar creates its own wireless connection, so you do not need cellular service while using it.
Built-in GPS also allows the PRO+ 2 to create depth maps when you cast it from shore or move across the water.
It can cast out to around 330 feet and scan down to around 330 feet under suitable conditions.
Special features:
- Extremely compact
- Built-in GPS
- Wireless connection
- Smartphone display
- Creates depth maps
- Works from shore or boat
3. Best Dedicated Handheld: HawkEye FishTrax 1C
The FishTrax 1C is worth considering if you want portability without using your phone as the display.
It has its own small color screen and a portable sonar sensor that can be floated, mounted, or trolled depending on your setup.
The sonar can read down to around 240 feet.
This makes it useful for kayaks, small boats, docks, and ice fishing.
Amazon currently carries the FishTrax 1C and related portable bundles, with recent listings around the $120 range depending on the package.
Special features:
- Dedicated color display
- Portable sonar sensor
- Up to 240-foot depth capability
- No smartphone required
- Works for several fishing styles
4. Best Budget Wireless Option: Venterior Portable Rechargeable Fish Finder
The Venterior is much cheaper than Deeper but still gives you a wireless sonar sensor.
Instead of using your smartphone, it comes with its own display.
You can see approximate fish location, water depth, fish size, water temperature, and bottom contour information.
The wireless sensor can also be tossed away from shore or used beside a kayak.
It is currently one of the more established budget fish finder brands on Amazon, with multiple portable models available.
Special features:
- Wireless sonar sensor
- Dedicated color display
- Rechargeable
- Fish size indication
- Water temperature
- Budget-friendly
5. Best Cheap Handheld Fish Finder: LUCKY Portable Fish Finder
The LUCKY handheld fish finder is about as simple as portable sonar gets.
You get a small handheld display connected to a sonar transducer.
It can display water depth, approximate fish depth, vegetation, and different bottom types.
Some versions can detect depth down to around 328 feet.
Amazon continues to carry several LUCKY fish finder models, making replacement or upgrading easier than with many generic portable brands.
Special features:
- Handheld design
- Very inexpensive
- Displays fish depth
- Bottom information
- Easy to carry
- Good first fish finder
Portable vs Castable Fish Finders
Not every portable fish finder is designed to be repeatedly cast with a fishing rod.
A portable fish finder simply means you can easily move the system between locations.
A castable fish finder is specifically designed to attach to your fishing line and be thrown away from shore.
If bank fishing is your main reason for buying one, a castable sonar is normally the better choice.

Conclusion
The best portable fish finder depends on how portable you actually need it to be.
The Garmin STRIKER 4 Portable Bundle is the best option if you want traditional sonar with its own display and GPS.
The Deeper PRO+ 2 is better if you want something small enough to carry almost anywhere and use from shore, a kayak, or a boat.
