1. Which trolling motor transducers stand out?
2. How do you choose a transducer for a trolling motor?
3. Which trolling motor transducer should you choose?

The best trolling motor transducer depends on your display and motor: the Lowrance Active Imaging 3-in-1 Nosecone fits specified Ghost motors and provides three sonar views, while the SplitShot offers flexible mounting for compatible HOOK2 fish finders.

A transducer sends and receives sonar signals, but the right choice also depends on how it mounts and which display can use its sonar. If you're still sorting out the basics, read what a fish finder transducer does before comparing models.

Which trolling motor transducers stand out?

The Lowrance nosecone is the clearest pick for compatible Ghost motors, while the SplitShot suits HOOK2 owners who want more mounting options. Humminbird users should check the model list carefully, since some picks here are adapters or brackets rather than complete sonar sensors.

We compared the stated mounting methods, display and motor compatibility, sonar views, and included components. Our score weighs specs, features and buyer feedback against what you're shopping for.

1

Lowrance Active Imaging 3-in-1 Nosecone Transducer: Best for Ghost imaging

9.0/10Our score

• SideScan, DownScan and CHIRP
• Supports 83/200/455/800 kHz
• Fits Ghost 47, 52 and 60 in motors
• 2-year warranty

This nosecone transducer is made for compatible Ghost motors and combines three sonar views. Check that your display supports the sonar functions you want.

See it on Amazon

Pros

• Three sonar views in one transducer
• Designed for three Ghost motor lengths
• 2-year warranty

Cons

• Compatibility is limited to specified Ghost motors
• Display compatibility should be confirmed

The Active Imaging 3-in-1 Nosecone is the most direct fit here for an angler with a Lowrance Ghost motor. Lowrance lists compatibility with the 47, 52 and 60 in Ghost models.

It combines SideScan, DownScan and CHIRP in one transducer and supports 83, 200, 455 and 800 kHz frequencies. The stated sonar features make it the most imaging-focused option in this group.

Lowrance also describes Ghost 360 imaging around the boat when used with the latest software. Check that your display and software support the feature before relying on it.

Pick this when you have a compatible Ghost and want several sonar views from a nosecone installation. For another compatible sonar setup, compare it with the best fish finder transducers.

2

Lowrance SplitShot Skimmer Transducer: Best for HOOK2 versatility

9.6/10Our score

• DownScan and CHIRP
• Fits Lowrance HOOK2 5, 7, 9 and 12 in fish finders
• Can mount on a trolling motor
• Built-in temperature sensor

A flexible mount choice for a compatible HOOK2 display, with DownScan and CHIRP views. Its range of mounting options includes trolling motor installation.

See it on Amazon

Pros

• Multiple mounting options
• Two sonar views
• Built-in temperature sensor

Cons

• Compatibility is specified for HOOK2 models
• Does not include SideScan

The SplitShot Skimmer is a flexible option for Lowrance HOOK2 fish finder owners. It fits the 5, 7, 9 and 12 in HOOK2 models and can be mounted on a transom, inside the hull, on a trolling motor or through a scupper hole.

Its DownScan and CHIRP views serve different needs: DownScan shows what is directly below, while CHIRP is used for fish-finding arches. The transducer also includes a built-in temperature sensor.

This is a sensible choice if you already own one of the listed HOOK2 displays and want the option of trolling motor mounting. It does not provide SideScan, so look elsewhere if viewing structure to the sides is a priority.

3

Humminbird 710198-1 XNT 9 20 T: Best for compatible Humminbird displays

9.3/10Our score

• Single/DualBeam transducer
• Built-in temperature sensor
• Compatible with many Humminbird series
• Maximum measuring depth 600 ft

This Humminbird transom transducer is a candidate for compatible displays when paired with suitable motor mounting hardware. Confirm your exact fish finder model and sonar capability first.

See it on Amazon

Pros

• Broad compatibility across listed Humminbird series
• Built-in temperature sensor
• Mounting hardware and instructions included

Cons

• Compatibility excludes some DI models
• Transom mount needs separate motor mounting solution

The Humminbird XNT 9 20 T is a transom-mount Single/DualBeam transducer that may suit a compatible Humminbird display when paired with an appropriate trolling motor mount. Its compatibility list covers many HELIX, Matrix and numbered series models, with exceptions for some DI units.

It includes a built-in temperature sensor and mounting hardware. The stated maximum measuring depth is 600 ft, but actual capability depends on the fish finder and setup.

This is a sensor, so you'll need a suitable mounting solution for the motor. Humminbird's AD XTM trolling motor adapter is intended for certain XNT transducer models, but verify the exact match before buying.

4

Humminbird 740087-1 AD XTM: Best for adapting an XNT transducer

9.6/10Our score

• Trolling motor adapter for compatible XNT transducers
• Fits a range of listed Humminbird transducer models
• 1-year limited warranty

This is mounting hardware, not a transducer. It adapts certain Humminbird XNT transducers for trolling motor use.

See it on Amazon

Pros

• Purpose-built for compatible XNT transducers
• Supports several listed transducer models
• 1-year limited warranty

Cons

• Transducer is not included
• Compatibility depends on the exact XNT model

The Humminbird 740087-1 AD XTM is an adapter for mounting specific XNT transducers on a trolling motor. It is not a transducer, so choose it only if you already have a compatible sensor.

Humminbird lists a range of compatible models, including XNT 9 20 T and XNT 9 DI T. Compare the full model number on your transducer with that compatibility list, since similar names do not always mean the same fit.

This adapter is a focused option for anglers who want to move a supported Humminbird transducer from a transom setup to a trolling motor. For a general look at mounting options, see our guide to the best transom mount transducer.

Wosijm 1840201 Transducer Mounting Kit for Humminbird: Best for standard through-bolt mounts

8.7/10Our score

• Mounting kit for standard through-bolt style
• Aluminum and stainless steel
• Cross-references 410150-1 and MKR-15

This replacement mounting kit suits a standard through-bolt setup and cross-references Humminbird 410150-1 and MKR-15. Verify fit with your motor and transducer before ordering.

See it on Amazon

Pros

• Standard through-bolt style
• Aluminum and stainless steel construction
• Cross-references named replacement parts

Cons

• Exact transducer fit should be checked
• Does not include a transducer

The Wosijm 1840201 kit is mounting hardware for a standard through-bolt setup. Its part references include 410150-1 and MKR-15, and it uses aluminum and stainless steel.

Treat this as a replacement mount to check against your existing parts and motor, rather than a universal fit. The kit does not include a transducer, and the stated fit information is broad, so verify dimensions and attachment style before ordering.

Choose it when your current hardware uses the named standard through-bolt style and the part references match your setup. A similar part number alone is not enough to confirm compatibility.

FENXDN 1840201 410150-1 MKR-15 Transducer Mounting Kit: Best for Minn Kota lower-unit mounting

8.4/10Our score

• Designed for specified Minn Kota lower-unit sizes
• Works with listed major transducer brands
• Mounting hardware included

This bracket is designed to clamp onto specified Minn Kota trolling motor lower units and fit transducers from several major brands. The transducer itself is not included.

See it on Amazon

Pros

• Lists four lower-unit sizes
• Compatible with several transducer brands
• Mounting hardware included

Cons

• Requires a listed motor lower-unit size
• Transducer is not included

The FENXDN kit is designed for Minn Kota trolling motor lower units in four listed sizes: 3-1/4, 3-5/8, 4 and 4-1/2 in. The bracket is described as compatible with Humminbird, Garmin, Lowrance and Eagle transducers.

It includes mounting hardware, but the transducer is sold separately. Check your motor's lower-unit size and the shape of your sensor before choosing it.

This kit is the most size-specific bracket in this roundup. It can make sense when your motor matches one of those measurements and you need a clamp-on mounting option.

How do you choose a transducer for a trolling motor?

Start with your fish finder model, then confirm the transducer and mounting hardware work with it. A transducer that physically fits the motor may still lack the sonar functions or display compatibility you need.

Does the transducer fit your fish finder?

Check the exact display model and transducer compatibility list before ordering. The SplitShot is specified for Lowrance HOOK2 displays, while the Humminbird XNT 9 20 T lists many compatible Humminbird series with some exceptions.

If you're comparing sensor types as well as mounts, our guide to the best transducer for fish finder explains the main tradeoffs. Your display's supported sonar features should guide the final choice.

What sonar views do you need?

Choose the views that match how you fish. CHIRP supports fish-finding arches, DownScan looks below the boat, and SideScan shows structure to the sides when the transducer and display support it.

The Lowrance nosecone combines all three views, while SplitShot combines CHIRP and DownScan. If a wider sonar cone is your main concern, see what a wide beam transducer is used for.

Which mount style matches the motor?

A nosecone transducer, adapter and clamp-on bracket solve different mounting problems. Confirm the motor model and lower-unit shape, then check whether the transducer is included or whether you need to reuse one you already own.

For a broader look at motor choices and fit, use our trolling motor buying guide. If your motor needs a separate power setup, our guide to wiring a 24V trolling motor covers that related task.

Does GPS come from the transducer?

A transducer provides sonar data, while GPS and anchor control depend on the trolling motor and compatible electronics. The trolling motor head with GPS guide explains what to check if those features matter to your setup.

Which trolling motor transducer should you choose?

Choose the Lowrance Active Imaging 3-in-1 Nosecone for a compatible Ghost motor and a need for SideScan, DownScan and CHIRP. Choose the SplitShot for a listed HOOK2 display and flexible mounting, or an adapter or mounting kit when you already own a compatible transducer.

For ice fishing, where the setup and use case differ, compare options in our best ice fishing transducers. Before ordering, match the exact display, transducer and motor models.

Frequently asked questions

Can you mount a transducer on a trolling motor?

Yes. Some transducers can mount directly on a trolling motor, while others need a compatible adapter or bracket.

Check the transducer model, motor shape and display compatibility together before choosing hardware.

A mount that fits the motor may still be wrong for the transducer.

Can a transom-mount transducer go on a trolling motor?

Some transom transducers can be adapted for trolling motor use. Humminbird's 740087-1 AD XTM is designed for specified XNT models, and the SplitShot can be mounted on a trolling motor.

Confirm the exact transducer and display models before buying a mount.

Does every trolling motor transducer support SideScan?

No. The Lowrance Active Imaging 3-in-1 Nosecone offers SideScan, DownScan and CHIRP, while the SplitShot offers DownScan and CHIRP.

Check both the transducer and display capabilities, since a transducer feature alone does not guarantee your fish finder can show that view.

Should you choose a transducer or a mounting kit?

Choose a transducer when you need the sonar sensor and its views. Choose a mounting kit or adapter when you already have a compatible sensor and need hardware to attach it to the trolling motor.

A mounting kit does not supply sonar by itself.
