7 Best Portable Fish Finders of 2019

#1 Garmin Striker 4 with GPS

Garmin Striker 4 with GPS

Garmin is a company that is known for its fish finders and it’s no surprise that one of the best portable fish finders on the market today is the Garmin Striker 4 with GPS and CHIRP transducer technology.

You will love the easy to read, 3.5-inch color screen and it’s highly sensitive GPS. The keypad is big and easy to operate. You can get back to your favorite fishing spots, boat docks, and ramps because you can save these right in Striker 4. Just follow the path that is laid out for you on the Striker 4 screen.

With the Chirp (77/200 kHz) sonar transducer technology, you get crystal clear images of fish and structures that lay underneath. Instead of sending out one frequency like other transducers CHIRP sends out a continues wave of frequencies coming up with much clearer results. You will be able to distinguish more easily what you are actually seeing. The transmit power on the Chirp is 200 W RMS and the peak to peak is 1,600 W.

The Striker 4 will track the speed you are going and it also swivels and tilts and includes hardware so that you can mount it to a trolling motor. You will appreciate this when the water is rough and you need the fish finder to be in a fixed position.

The built-in flasher works great especially when you are ice fishing. The flasher will indicate if the bottom is muddy or solid. I will also show where your bait is and at what depth the fish are at when they swim through the sonar beam.

This fish finder is easily portable when you opt for the portable kit which is sold separately. The portable kit for the Striker 4 includes:

  • Protective carrying bag
  • Rechargeable Battery
  • Battery Charger
  • Suction Cup Transducer Mount and Float
  • Transducer cable management and storage

Deeper Pro +Smart Sonar

Deeper Pro Plus Smart Sonar portable wireless fish finder.

The Deeper Smart Sonar Pro is built for onshore anglers. It’s a castable fishfinder with a castable range of 330 feet. No other castable fish finder can cast as far. The GPS allows the Deeper Pro the map right from the shore. Cast this fish finder to where you are planning on fishing and reel it in. You get detailed bathymetric maps from shore. To my knowledge, this is the only castable fish finder that can create maps like this.

Not only can you cast the Deeper Pro out to 330 feet you also get a wide scanning area of 55 degrees that the sonar beam can cover. If you want a detailed scan just switch to that and it will limit the coverage to 15 degrees.

And Talk about the depth this fish finder scans to 260 feet which is 100 feet deeper than any other comparable fish finders on the market today. That is deep, especially when scanning from shore.

You will appreciate the dual-beam transducer that the Pro has installed in it. It has a target separation of 1” and scans 15 times per second. This provides for very accurate readings and with the use of WiFi instead of Bluetooth, you get those readings lighting fast in real-time.

You get to mark fish and see fish archways. Also, add fish tags and depth tags. You can see the vegetation and fish with the split-screen scanning. View the bottom contour with ease of clarity.

Choose from 3 color pallets which helps you view the display better whatever the weather is outside. You will know the depth and water temperature as soon as the Deeper Pro+ hits the water.

This is an all-around best castable portable fish finder that money can buy! The Deeper Pro+ Sonar fish finder is available on Amazon and free shipping is available with a Prime account.


ReelSonar iBobber Bluetooth Smart Fish Finder

ReelSonar iBobber Smart Fish Finder

The iBobber by ReelSonar is a handy little castable fish finder to have. As a matter of fact, it is the smallest fish finder you will find anywhere. The iBobber is wireless with Bluetooth capabilities that will sync up to your iPhone or Android smartphone from 100 feet away.

You can choose between raw sonar and fish tagging views. Fish will get tagged in your screen in two different colors depending on the length of the fish. Fish that are under 15” get an orange tag and fish over 15” get a green tag. This helps you determine which fish are worth going after before you even start fishing.

The sonar reads to a depth of 135 feet which is a long way down there and if you are fishing off the shore that should be plenty.

There is a trip log with the type of fishing, conditions, lure, number and species of fish that you caught, water temperature, location, time and date. This is great if you are an angler who likes to take notes of your trip.

You can tag your fishing spots with built-in GPS and interactive mapping. The iBobber is compatible with Google watch and iWatch. There is also social media share capability on the app thats provided free.

The battery is rechargeable and lasts up to 10 hours which is perfect for a whole day of fishing. The first time charging the battery takes 6 hours and after it’s been used once it takes about 2 hours to charge.

A little fish finder like this is perfect anglers who fish from the shore or for boaters who can’t get your onboard sonar to certain areas. Just cast the iBobber out to those limited areas and you are in business.

The iBobber is available on Amazon and you get free shipping with a Prime account.
