12 best depth finders for boats

Depth finders for boats, often referred to as fish finders or depth sounders, are essential marine electronics used by boaters and fishermen to determine the depth of water beneath their boat. These devices utilize sonar technology to measure water depth and identify underwater objects, including fish. Here are some key aspects to know about depth finders for boats:

  1. Sonar Technology: Depth finders work on the principle of sonar (Sound Navigation and Ranging). They emit sound waves (sonar pulses) into the water, which bounce off underwater objects and return as echoes. The time it takes for these echoes to return to the device is used to calculate water depth and identify objects.

  2. Display: Most depth finders feature a display screen that shows the depth of water in real-time. The display may also provide information about the bottom structure, temperature, and the presence of fish or other marine life.

  3. Transducer: The transducer is a crucial component of a depth finder. It is mounted on the boat's hull or transom and emits the sonar pulses into the water. The transducer also receives the echoes and sends the data to the depth finder unit for processing.

  4. Fish Identification: Many modern depth finders come equipped with fish-finding capabilities. They can differentiate between different types of underwater objects and mark fish on the display.Some advanced models even provide fish size estimates.

  5. Bottom Composition: Depth finders can help boaters identify the composition of the seafloor, which is useful for finding productive fishing spots. They can distinguish between soft bottoms (mud, sand) and hard bottoms (rocky or reef areas).

  6. Water Temperature: Some depth finders also display water temperature readings. This information is valuable for anglers as it can indicate preferred water temperatures for various fish species.

  7. GPS Integration: Some depth finders are integrated with GPS technology, allowing boaters to mark waypoints and track their route. This feature is especially beneficial for returning to favorite fishing spots or navigating in unfamiliar waters.

  8. Depth Alarms: Many depth finders can be set to trigger depth alarms. These alarms alert the operator if the water depth falls below or rises above a preset limit, helping to prevent grounding or collision with underwater obstacles.

  9. Mounting and Installation: Proper installation and mounting of the transducer are essential for accurate depth readings. The location and angle of the transducer affect the device's performance.

  10. Maintenance: Regular maintenance, such as cleaning the transducer and checking for obstructions, is necessary to ensure the depth finder operates optimally.

Depth finders are valuable tools for boaters, whether for navigation, fishing, or safety purposes. They provide essential information about the underwater environment and help boaters make informed decisions while on the water.

STRIKER 4

3.5-inch CHIRP Fishfinder with GPS.

Navigate Easily with Waypoint Map

Since the STRIKER fishfinder series includes high-sensitivity GPS, you can see your position in relation to waypoints you have marked. Use the waypoint map to easily view, mark and navigate to locations such as brush piles, stumps and docks. It’s also a great tool for finding your way back to the boat ramp.

Check Your Speed on Screen

You can quickly and easily see your boat’s speed on the screen of your STRIKER fishfinder. It’s a great tool to make sure you are trolling at the right speed for the lure you’re using and for a particular fish species. It’s also a good way to tell if you are going the right speed in wake-controlled areas.

Take Your Fishfinder Anywhere

A portable kit is available to protect and carry your STRIKER fishfinder with GPS, so it’s perfect for kayak, canoe or ice fishing. It includes a sealed, rechargeable battery with charger, built-in transducer cable management and storage and suction cup transducer mount and float.

Experience the Clarity of CHIRP

STRIKER 4 fishfinder includes a Garmin CHIRP (77/200 kHz) transducer, which provides a visibly higher level of clarity and detail for fish and structure than traditional 77/200 kHz transducers.

Instead of sending just 1 single frequency, CHIRP sends a continuous sweep of frequencies, ranging from low to high, then interprets them individually upon their return. Since the frequencies provide a wider range of information, CHIRP sonar technology can create crisper fish arches with greater target separation.

You also can upgrade to high-performance Garmin CHIRP technology, which provides crystal-clear sonar images with even more remarkable target separation and resolution from shallow to deeper depths. For better fishing, bottom contours are more visible, even at higher speeds, and signal noise can be suppressed at greater depths to provide a more timely interpretation of what’s below.

Humminbird HELIX 5 G2 Series Fish Finders

There’s no such thing as 'too early' or 'too far.' High expectations go with the territory. The HELIX 5 Series answers the call with an uncompromising widescreen color display. Available on select models, Humminbird CHIRP Digital Sonar and Imaging Sonar reveal the lake bottom, while GPS mapping, AutoChart Live and Humminbird Basemap show you the way.

Feature for feature, it has what it takes to win the day. Do you? No doubt.

Includes transducer and mounting hardware, power cable and gimbal mounting bracket.

2D Sonar

If your goal is to locate and see fish more clearly, start here. Humminbird’s 2D sonar offerings are far from two-dimensional. Whether you’re fishing freshwater lakes, coastal waters or the ice, you’ll find the right solution for your environment and prey.

SwitchFire

SwitchFire lets you control the way your returns appear. With two display modes—Max Mode and Clear Mode—you can choose how much detail, including fish, structure and thermoclines, you want to see or un-see.

Dual Beam

With a wide beam for more search area or a narrow beam for more precision, DualBeam shows you fish and the bottom. DualBeam Plus lets you combine the two beams for even more detail.

Digital CHIRP

CHIRP stands for 'Compressed High Intensity Radar Pulse.' That’s a fancy way of saying it can show you fish that other forms of 2D sonar can’t. How’s that? CHIRP scans the water for fish similar to the way the seek function on your truck’s radio scans the airwaves for FM stations. By covering a wide range of frequencies, CHIRP produces more accurate, more detailed returns of fish, structure and the bottom.

Imaging - It's all in the details

Amazing Humminbird Imaging sonar shoots high-frequency beams below the surface to reveal structure, cover and contours with crystal clarity.

Side Imaging - Nowhere to Hide

Gain an unprecedented, side-to-side perspective on the world below the surface with Side Imaging. In an instant, the ultra-thin beam scans the area to the left and right of your boat location. The return image for each slice is then added to the images taken immediately before and after to build an incredible view of the lake bottom. (image displays MEGA Side Imaging)

Down Imaging - Look Out Below

Get a fish-eye’s view of what’s happening below your boat with Down Imaging. These incredible images are created with high-frequency sound waves emitted in ultra-thin slices. The sonar returns from these waves produce a 'portrait.' As you patrol the water, you’ll watch timber, brush, bridge pilings, rocks and any other structure pop with stunning detail. (image displays MEGA Down Imaging)

Built-In Basemap - Ready to fish, right out of the box

We’ve enhanced our standard Basemap to deliver more detail and a superior angling experience. The Humminbird Basemap is built into all SOLIX Series and GPS-equipped HELIX Series G2/G2N models. Based on freshwater data from LakeMaster and NOAA, the most-trusted saltwater source, these accurate maps provide you with a clear view of underwater terrain. Identify buoys, daymarkers, hazards, marinas and countless other navigation aids and points of interest with our comprehensive icon system. You’ll also see contours, depth markings and, for coastal areas, spot soundings. On the water, confidence is key. And the Humminbird Basemap delivers.

Autochart Live - Create your map-sterpiece (On select models)

Build richly detailed maps of your favorite fishing spots in real time with Humminbird AutoChart Live, available on the SOLIX Series and all GPS-equipped HELIX Series models. Map the water as you drive the boat, with eight hours of built-in recording time. Once your map is live, view it with vegetation, bottom hardness and depth contours to locate the best fish-holding areas. Also, use it with i-Pilot Link Follow and other patented Humminbird LakeMaster features. The future of digital charting has arrived. Better get on board.

Navigation - Built-In GPS

Get unparalleled GPS technology out of the box. Many Humminbird fishfinders have our powerful Precision GPS/WAAS receiver built right in and provides fast position fixes accurate within 2.5 meters. For those models without it, there are several options: Add the Humminbird Precision GPS/WAAS receiver for permanent GPS capability on your boat. Use Humminbird’s adapter and the NMEA output on your own handheld GPS unit, or use Humminbird’s InterLink to allow two fishfinders to access one GPS receiver.

User questions & answers

Question: Does this Garmin fish finder comes installed with maps (Marine maps
Answer: There is no way to put any maps on this unit but it does have storage to make your own maps. It has a mapping feature so you can map the depths of your favorite lake. The specs says it will hold 1 million acres of lake maps. Granted, you have to be on a boat and troll to do the mapping but it does work and it works rather well.
Question: For in hull transducer mounts for a fiberglass boat, Garmin suggested putting the transducer in a container full of antifreeze. Any other methods
Answer: I can’t speak to fiberglass as I use mine on kayak. However I do use my transducer shooting thru hull attached with duct seal that forms a reservoir around transducer and then I add water. That works perfectly! Duct seal is $3 at Lowe’s or Home Depot.
Question: What's the difference between this and the "garmin striker 4 with transducer, 3.5" gps fishfinder with chirp traditional transducer
Answer: This one has a feature where you can contour maps the bottom of any lake or river you're in.
Question: how many holes do i need to drill to install the transducer
Answer: Don't drill holes in your boat. Find an old 3/8-1/2" plastic cutting board and cut a 4x4 piece out of it and using 3m sticky tape mount it to the transom and use short screws to mount the transducer to the piece of cutting board. Did that back in 1979 and has never come loose.
Question: Whats the maximun depth that it can read
Answer: It’s in the description I believe. Otherwise YouTube has this information
Question: Will this work in shallow waters? What is the minimum depth it will read accurately? Read a review where it was said to lose use under 10 feet
Answer: I know from experience it can read depths as shallow as 1 foot but I don’t know the exact limitations or specs. The problem that renders this and any fish finder useless in shallow water is the amount of vegetation and its direct proximity. In shallow water with dense vegetation reaching the surface you’re most likely only going to see screen noise displayed which may effect the abilities to properly gauge water depths. If there is no vegetation and the ground is of solid structure then this will work fine in water 10’ or less.
Question: Can the transducer be mounted on the trolling motor
Answer: Yes it’s come with all the hardware needed to install you might have to change some things depending on your trolling motor
Question: Will I be able to see the screen with polarized sunglasses
Answer: Yes you can because I am using as well the polarized glasses with a light yellow tint

Humminbird HELIX 5 G2 Series Fish Finders

There’s no such thing as 'too early' or 'too far.' High expectations go with the territory. The HELIX 5 Series answers the call with an uncompromising widescreen color display. Available on select models, Humminbird CHIRP Digital Sonar and Imaging Sonar reveal the lake bottom, while GPS mapping, AutoChart Live and Humminbird Basemap show you the way.

Feature for feature, it has what it takes to win the day. Do you? No doubt.

Includes transducer and mounting hardware, power cable and gimbal mounting bracket.

2D Sonar

If your goal is to locate and see fish more clearly, start here. Humminbird’s 2D sonar offerings are far from two-dimensional. Whether you’re fishing freshwater lakes, coastal waters or the ice, you’ll find the right solution for your environment and prey.

SwitchFire

SwitchFire lets you control the way your returns appear. With two display modes—Max Mode and Clear Mode—you can choose how much detail, including fish, structure and thermoclines, you want to see or un-see.

Dual Beam

With a wide beam for more search area or a narrow beam for more precision, DualBeam shows you fish and the bottom. DualBeam Plus lets you combine the two beams for even more detail.

Digital CHIRP

CHIRP stands for 'Compressed High Intensity Radar Pulse.' That’s a fancy way of saying it can show you fish that other forms of 2D sonar can’t. How’s that? CHIRP scans the water for fish similar to the way the seek function on your truck’s radio scans the airwaves for FM stations. By covering a wide range of frequencies, CHIRP produces more accurate, more detailed returns of fish, structure and the bottom.

Imaging - It's all in the details

Amazing Humminbird Imaging sonar shoots high-frequency beams below the surface to reveal structure, cover and contours with crystal clarity.

Side Imaging - Nowhere to Hide

Gain an unprecedented, side-to-side perspective on the world below the surface with Side Imaging. In an instant, the ultra-thin beam scans the area to the left and right of your boat location. The return image for each slice is then added to the images taken immediately before and after to build an incredible view of the lake bottom. (image displays MEGA Side Imaging)

Down Imaging - Look Out Below

Get a fish-eye’s view of what’s happening below your boat with Down Imaging. These incredible images are created with high-frequency sound waves emitted in ultra-thin slices. The sonar returns from these waves produce a 'portrait.' As you patrol the water, you’ll watch timber, brush, bridge pilings, rocks and any other structure pop with stunning detail. (image displays MEGA Down Imaging)

Built-In Basemap - Ready to fish, right out of the box

We’ve enhanced our standard Basemap to deliver more detail and a superior angling experience. The Humminbird Basemap is built into all SOLIX Series and GPS-equipped HELIX Series G2/G2N models. Based on freshwater data from LakeMaster and NOAA, the most-trusted saltwater source, these accurate maps provide you with a clear view of underwater terrain. Identify buoys, daymarkers, hazards, marinas and countless other navigation aids and points of interest with our comprehensive icon system. You’ll also see contours, depth markings and, for coastal areas, spot soundings. On the water, confidence is key. And the Humminbird Basemap delivers.

Autochart Live - Create your map-sterpiece (On select models)

Build richly detailed maps of your favorite fishing spots in real time with Humminbird AutoChart Live, available on the SOLIX Series and all GPS-equipped HELIX Series models. Map the water as you drive the boat, with eight hours of built-in recording time. Once your map is live, view it with vegetation, bottom hardness and depth contours to locate the best fish-holding areas. Also, use it with i-Pilot Link Follow and other patented Humminbird LakeMaster features. The future of digital charting has arrived. Better get on board.

Navigation - Built-In GPS

Get unparalleled GPS technology out of the box. Many Humminbird fishfinders have our powerful Precision GPS/WAAS receiver built right in and provides fast position fixes accurate within 2.5 meters. For those models without it, there are several options: Add the Humminbird Precision GPS/WAAS receiver for permanent GPS capability on your boat. Use Humminbird’s adapter and the NMEA output on your own handheld GPS unit, or use Humminbird’s InterLink to allow two fishfinders to access one GPS receiver.

User questions & answers

Question: Does the unit turn left/right on it's mount as well as up and down
Answer: i had to change the mount set up alittle but yes i got mine to spin about 180 degrees
Question: Can i confirm the meaning of inside hull or transom? does inside hull mean it can be mounted amidships through hull
Answer: This is for Kayak users. Inside Hull of Kayak or transom mounted outside.
Question: Is the humminbird 410150-1 water proof
Answer: Yes. Fishing in Central Florida it seems it is getting wet all the time. Go for it. . . . .
Question: Does this come with transducer
Answer: Yes :) Flush Mount transducer, 20’
Question: Please i need a trasceduser cable replacement. How much will it cost me
Answer: Usually we didn't sell the transducer alone. If you already bought fish finder from us before, please contact us through amazon message and we will give you the offer for the transducer alone.
Question: It works in salt water
Answer: Yes,this Lucky fish finder can work well in salt water. It is suitable for ocean、lakes and rivers. Hope this helps.
Question: can you mount the transistor in side the kayak
Answer: Usually people will fix the transducer on the hull of the kayak (the outside). Because the transducer can only be working when it touches the water.
Question: Does it work well for ice fishing
Answer: Yes it works well for ice fishing, although you must drop the transducer below the ice in order for it to read depth accurately. I also found that it has the potential to mis-detect large tube jigs as a fish, but I actually don’t mind that as it tells me how deep my bait is. I also use this with my kayak mounted with the bracket, so I get double duty. Battery life is fantastic even in below zero temps. I’ve been out with it on several outings below freezing and I’m still on the same set of batteries! I would recommend this product.
