The Best 3D Fish Finders

fishingFishing technology has come a long way over the years. There are so many more fish finder options available to anglers than there once was. If you are willing to invest, the days of those bulky, hard to read, not very accurate, not very detailed fish finders are over.

The best 3D Fish Finders will absolutely impress you with the detail they provide. The imaging is incredible, but these fish finders aren’t cheap. For serious fisherman that want to map out lakes, and have every possible fishing advantage, here are some of the best 3D fish finders reviewed.

Important note: Most of these 3D fish finders will require you to purchase the proper display screen as well as the actual 3D imaging transducer. These two elements must be purchased together for it to work properly. Some packages will be selling these separately, why some will bundle both items together. Make sure if you are buying just the 3D imaging part that it will function properly with your current display. Also make sure that all software is up to date before you install.

Lowrance HDS-7 Gen 3 Fish Finder Review

Lowrance HDS-7 Gen 3

This is the complete set – all 3 necessary parts!

Any 3D fish finder review wouldn’t be complete without the Lowrance HDS-7 Gen 3. This is one of the best 3D fish finders that money can buy, and it makes the old school fish finders we grew up with look obsolete.

There are three parts to this fish finder that can be purchased together, or individually. You will need the HDS-7 Gen 3 screen, Lowrance’s Structure Scan 3D Module, and the Structure Scan Transducer. Part one is simple, make sure you have all the necessary components and make sure that all of your software is up to date, or it will not function properly.

Part two is that you will need to mount the 3D imaging transducer to your boat and making sure all the cables are connected properly from the transducer to the graph. It is important to read the manuals, and again, the 3D structure scanning transducer will only work with the proper display. Instead of explaining the entire installation process, check out the YouTube video at the end of the article. They do a really nice job of walking you through the entire installation process.

Lowrance 3D Fishfinder StructureScan

This is the Structure Scan/Transducer – no display

The biggest highlight of this fish finder is the screen display. It is phenomenal. It is a 7 inch high definition screen that is backlit, so it provides easy viewing no matter how bright it is outside. The images are incredibly detailed, it isn’t just a block on your screen that is supposed to represent brush or underwater structure.

The images are 3D, so you are going to know everything that is going on underwater. Structure, water depth, where the fish are, if you want the data, you are going to be able to get it. Expect to pay in the thousands of dollars for all the necessary equipment for this fish finder. In return, you will get the most detailed fish finding imagery you have ever seen.

Humminbird 3D Fish Finders

Humminbird 360° Transducer Deployment System

Humminbird 360° Transducer Deployment System

Humminbird also offers what many would consider 3D imaging, or what they refer to as 360 imaging. This product will offer you a full 360 view around your boat. The sonar basically rotates automatically around your vessel, letting you know everything that is going on in a 300 foot circle.

The imaging is fantastic, letting you not only know where the fish are, but what type of structure is present. You can also isolate the imaging, so instead of doing a full 360 degree sweep, you can look at a 180 degree area in front or behind the boat. There is no place for fish to hide when this product is in use!

For this to work properly, you need to buy the Humminbird 360 Imagining transducer. It basically looks like a long pipe that can be mounted quickly to the front or back of your boat. Once mounted, the transducer is placed into the water and it starts gathering information for you.

Humminbird 409930-1 HELIX 9 DI GPS Fishfinder

Humminbird 409930-1 HELIX 9 DI GPS Fishfinder – Which it is compatible with.

For this product to work, it must also be paired with any of the ethernet ready, side imaging ready, Humminbird fish finder displays. A full list of acceptable models can be found on the Humminbird website, but include the ION 12, ION 10, ONIX10ci, ONIX8ci, HELIX 9, HELIX 10, and HELIX 12 models.

The 360 technology and mount will normally cost around $1,000. Add to that the cost of the fish finder model that you connect it to. We can’t stress this enough, if you try to use this with a non-ethernet, non-side imaging fish finder it will not work properly!

The biggest complaint with many people about this product is it cannot be integrated with some of the older fish finder models.

FishHunters Directional 3D Fish Finder Review

FishHunter Directional 3D Wireless, Portable Fish FinderThe biggest reason to pick the FishHunter Directional 3D fish finder over some of the other options is its portable capabilities. This option does not have to be mounted to a boat. It uses a Wi-Fi connection in the transducer to connect to your smart phone or tablet.

How this product works is really simple. You cast out or place the transducer into the water, and it is going to start kicking data back to your smartphone or table once you download the app. Again it used a Wi-Fi connection to connect, but you do not have to have an internet connection and it does not require any data.

This product creates really neat 3D maps and 3D bottom contouring. The ball you cast out into the water actually has 5 transducers that relays information, providing a larger coverage area that most of the other portable fish finders on the market. Those transducers also help to provide a lot of detailed information when you are using the mapping features.

The fish finder itself will gather information for you from up to 200 feet away, and in water depths of 4 feet to 150 feet. It works really well for ice fishing, working in temperatures up to -20 degrees. In ice fishing situations, the transducer will actually float on top of the water in your fishing hole instead of needing to be fully submerged.

With a battery life of up to 10 hours, this is a great fish finder. However, your tablet and smartphone might not be able to last that long.

FishHunter also makes a non-3D portable fish finder call the FishHunter Pro. This version is very effective, but does not give you the 3D details that the FishHunter Directional 3D Version gives you. Make sure you are purchasing the right version if you are hoping for 3D images. If you want a portable fish finder, but don’t need the 3D imaging we would recommend looking at Deeper Fish Finders.

The price point is also much more affordable with this option. However, it has a lot more limitations than other boat mounted options.

Other Notes

There are also a few other companies like Garmin that make 3D fish Finders. A Garmin 3D fish finder will even show you your lure being reeled in and if a fish is chasing it. Just like with Humminbird or Lowrance you are going to have to buy the 3D mapping technology so it can be mounted to your boat, as well as the appropriate fish finder that will work with it.

If these options are just too expensive for you, there are some very inexpensive but effect portable fishfinders available.

Final Thoughts

These fish finders are for the most serious of anglers. They will give you every fishing advantage you can imagine. They do take a little bit of time to get used to, but the data they give you is phenomenal. And you won’t have any complaints about how detailed the imaging is. It will be pretty hard to come up with an excuse for not caching more fish with one of these fish finders in action!

Here is the promised video showing the Lowrance 3D Structure Scan being installed.
