FishSpy Echo Pro Review – The Best Castable Sonar You Can Buy

Our latest review is an exciting one, the FishSpy Echo Pro is a shiny new piece of tech and it is a castable floating sonar/fishfinder device made by Total Fishing Gear. Now I hear you, there are other castable sonars available, Deeper and Ibobber to mention just a couple but the FishSpy version has something that none of the others has… an inbuilt underwater camera capable of not only recording footage but high quality live video streaming straight to your mobile phone! 

To say we were excited to get the FishSpy Echo Pro out on the bank is an understatement. To test the device we took it first to a large flooded reservoir local to us called Wintersett and then to a local brick pond to complete our review. Has FishSpy raised the bar on castable fish finders? Find out below.

FishSpy Echo Pro – The Setup

Setting up the FishSpy Echo Pro is really easy with absolutely no fuss. Once charged setup takes about 5 mins.  Simply take the device out of its box, unfasten the cover that protects the charging port and charge it with a standard micro USB. I found a small coin works best to open the cover.

Use a small coin to open the cover that protects the charging port. Remember to fasten it securely or your device will not be waterproof

You will know when the device is charging because a red light shows near the charging port.

The light shows the FishSpy Echo Pro is charging. It turns green once the device hits fully charged. Note the two metal pins, it’s these you need to wet to activate your device.

Once the FishSpy Echo Pro is fully charged the light will change to green. Unplug the device and remember to securely fasten the cover that protects the charging port. This cover keeps the sonar waterproof. 

Now you are going to want to connect the device to your phone. I did this at home but you could just as easily do it on the bank. Simply wet the two metal pins on the bottom and this will turn the FishSpy on. Go to your phone and search for wifi networks until the Echo Pro network is visible. On my phone, this displays as epxxxx. Hit connect. All done.

The App

Go to your app store and download the FishSpy Echo Pro App. The app is great, no fuss and simple to use interface. 

I tested the app on my Samsung S9 but I’m pretty sure the IOS version is exactly the same. Just a quick note on connectivity… When you are ready to use the device in the water be sure to turn off mobile data. Leaving this on can prevent the FishSpy Echo Pro from working correctly.

The Interface is simple and really easy to use. I tested mine on a Samsung S9


This section of the app is where you can build bathymetric lake maps that can be used to study when you get home or planning future sessions. All you need to do is download the map of your lake before you go fishing. All of this can be done inside of the app itself and is quite simple to do.

When you cast your new FishSpy Echo Pro it will automatically start to create an accurate map of the lake/pond/river. This is invaluable when targeting specific fish through different seasons. I found it amazing for finding drop-offs and deeper sections of water. Ideal for winter lure fishing predator fishing.

The meat and drink of any fish finder are, of course, its sonar capabilities and we are delighted to say that FishSpy nailed it. My experiences with other fishfinders have been inconsistent. Sometimes they would work great but on other occasions, they didn’t work at all or would drop signal a short distance from the rod. Not the FishSpy Echo Pro.

The sonar is faultless and reliable. It actually helps you to find fish and fish-holding features. The depth is accurate and the longitude and latitude are on the button.

In my review of the FishSpy Echo Pro I chose a venue I had traditionally struggled. The goal is to find features I could come back to in the future. Check this out… perfect spot for Perch I cant wait to drop a lure in there.

Nice drop off

During the review, I also found a huge shoal of smaller fish. If smaller baitfish are around you know who else is going to be close by Pike! Perfect when lure angling for Pike, perch or zander.

I was excited to give this a go and I wasn’t disappointed. The venues I tested on were quite murky due to all the rain we have had here in South Yorkshire but the FishSpy Echo Pro was great to about 10 ft. After that the images were good but the bottom was not clear. When the weather picks up I’m sure I will use this element of the device even more.

Not only does the camera record the footage it streams it directly to your phone. This is a brilliant feature that I really enjoyed using. Previously when I got the fish finder out my son would moan and groan that it was boring and for him it was. Now he gets to see what is under the water. I think he actually prefered using the FishSpy Echo Pro camera to actually fishing!?! Any footage you take can be recorded and downloaded to your phone for review when you get home.

Is the camera the only reason to buy the FishSpy? No definitely not because the sonar is amazing and the bathymetric lake mapping is dynamite. The camera is more of an added bonus really. It is wonderful for checking out those features and It satisfies my intrigue of what lies beneath which is fantastic. Another great use would be for bait anglers that like to pre bait their spots. The device could actually be used to check if your bait has been eaten!


This section of the app is where all your sonar graphs are stored. Perfect for reviewing when you get home or prior to your next trip. These can be shared with friends should you choose to be so generous!


While reviewing the FishSpy Echo Pro I spent the majority of the time using the device and not actually fishing. I wanted to be sure I had given the device a good working over before writing this review for our readers. However, my friend asked to take the device out for a night session on a local river. He’s a specimen fisherman more than a predator angler but had been struggling to catch in recent sessions. The next morning I woke up to this picture in my WhatsApp!


The FishSpy Echo Pro is a stunning device and quite simply the best castable sonar on the market and a wonderful addition to your predator fishing tools. The sonar is at least as good as any other available and probably better. Automatically building bathymetric lake maps is a fantastic feature and the camera is a great extra that sets it apart from its main competition the Deeper. Go buy it.


  • Stunning sonar that is a joy to use
  • Great app with simple user interface
  • Brilliant connectivity
  • The camera provides high-quality images and streaming directly to your phone
  • Build bathymetric lake maps

I couldn’t find any major cons with this device so this section is more ‘things to consider’

Things to consider

  • I did not have an issue with battery life but it is less than some other castable sonar’s on the market
  • I couldn’t find any option to check the water temp
  • It’s not cheap but it is in line with other castable sonars and you get more for your money with the camera

Buy the Fish Spy Echo Pro

  1. I decided on this instead of the deeper chirp thanks to your review. Had it out yesterday for the first time and its a brilliant device. Caught a couple of Pike after locating a large shoal of baitfish. Its going to be worth its weight in gold, especially in winter. Thanks to you for recommending it.
