The Features of Venterior Portable Fish Finder


Venterior’s fish finder features a single-beam transducer. You may think that that’s a serious downside as dual-beam models are quite common nowadays, but for its price, this model does what it is designed to do perfectly.

The 45-degree angle beam will spot fish on depths from 2.3ft to 328.08ft. For such a small fish finder, those are quite good numbers! This means that the sonar transducer of this model will allow you to spot fish targets in fairly deep water bodies.

The transducer is attached to the control unit via a 25ft cable.

You can cast the transducer into the water to fish onshore, attach the Side-Scan Adapter to the boat with the mounting tabs to fish from your boat, or attach the sensor to a handle and lower it into the water.

Also, this fish finder comes with a removable transducer float with a rubber stopper.

The transducer doesn’t deliver readings on the water temperature, but it is quite expected with such a simple and affordable model.

Fish Detection

The transducer of this portable fish finder spots only targets in motion, so you won’t get data on underwater objects and structures. Besides, you cannot use the fish finder to detect your bait.

Otherwise, this fish finder easily spots fish bigger than 10cm. By adjusting the sensitivity setting, you can regulate the size of the fish the sonar transducer will spot.

Here, we should mention that you cannot see the size of the fish on the display of the fish finder. It will only show big fish if you set the sensitivity to low.

Another point to keep in mind is that you should keep the speed of your boat lower than 5mph, otherwise, you will interfere with the sonar transducer.


This fish finder features a TN/anti-UV LCD b/w display with a green LED backlight. Don’t think that this model will lack visibility of the readings due to the colorless display.

This fish finder doesn’t deliver detailed data, to begin with! Such a screen is all you need to view the data of the transducer, and that’s the most important thing.

The display shows data in the position of fish and depth. With the latter, you can switch between meters and feet. That’s pretty much all the display of this fish finder is capable of, but that is not a bad thing for such an affordable model.

As for the downsides, we can mention the small display and the absence of colors. But that is not as critical as with other models delivering much more detailed readings. With Venterior’s fish finder, you won’t have to struggle to distinguish between individual objects and underwater structures.

That’s why the b/w small display won’t be an Achilles heel of this fish finder. There is one small downside with the depth readings as well. The fish finder doesn’t save the measurement unit you have selected, so you will have to switch to it every time you turn off the device.


As for the controls, you have three buttons – setup, enter, and an on/off button. Via the buttons, you can regulate the sensitivity, activate battery saving mode, and change the unit of measurement.

No convoluted control panels and in-depth user interfaces! If you are tight on budget or want something really simple, this fish finder will be a great choice for you.

Easiness of Use

What about the easiness of use? Simpler means fewer things to worry about! You won’t have any hassle with regulating this fish finder and setting it up for your fishing trip. You only need to turn it on, set the sensitivity, and cast the transducer into the water/mount it to the boat, and that’s it!

This model is wireless and operates on 4 AAA batteries, which is really convenient. A bad thing is that there are no batteries included with this fish finder, but that’s not a too serious issue.

Lastly, you can use this fish finder in a wide range of temperatures between -20C and 70C (-4F and 158F)! You could even go ice fishing with this little guy!

Frequently Asked Questions

  • Can this fish finder be used for ice fishing without drilling a hole?

Yes, you could do that. Just make sure you remove the snow from the surface of the ice to make sure it is smooth. In addition, keep in mind that if there is any air between the sonar sensor and the ice or the water below the ice, you won’t get proper readings. In this case, you will either need to find a better spot or drill a hole in the ice.

  • How long does it work on a single battery set?

It will depend on the capacity of the batteries. Generally, the fish finder can last about 4 hours with regular four AAA batteries. You can get rechargeable batteries if you want to have a more convenient option on hand.

No, the sensor cannot do that.
