The 7 Best Transducer Mounting Arms

This wiki has been updated 21 times since it was first published in December of 2018. Fishermen know that when your transducer isn’t positioned correctly, your depth finder won’t work properly. They’re also aware that when your depth finder isn’t firing on all cylinders, it’s tough to find the fish. Before your next angling outing, pick up one of these mounting arms, so you don’t have to reach down and fiddle around with your gear every time it gets bumped out of place. When users buy our independently chosen editorial recommendations, we may earn commissions to help fund the Wiki.

1. Scotty 140

The ease of use that you’ll enjoy with the Scotty 140 (appx. $21) is nice, but you should also note its sleek, striking appearance. The arm remains reliably in place, so you won’t have to worry about an off-kilter transducer affecting the fish finder’s accuracy.

Swivels 360 degrees
Easy to swing up out of the water
Ideal for use with kayaks

2. Ram Diamond

Professional in both appearance and performance, the Ram Diamond (about $64) features a tough metal bar you can easily shape to your liking. It’s designed for quick retrieval, which helps eliminate the risk of damage when you’re beaching or navigating shallow waters.

Remains steady even at high speeds
Works with an array of transducers
Durable and corrosion resistant

3. Brocraft Kayak

Don’t worry about a learning curve with the Brocraft Kayak (around $24) — installation is simple and operation is very straightforward. You can set it up in a variety of ways, and it remains in place even if you’re cruising full-tilt boogie across the lake.

4. Scotty 141

The Scotty 141 (around $27) provides stability and maneuverability in equal measure, as it’s easy to adjust and super secure once you lock it into place. It’s compatible with Scotty track mounts, and even some other brands as well, if you prefer to use that type of system.

5. YakAttack RMS-1046

The 18-inch YakAttack RMS-1046 (around $49) is strong and versatile, with an aluminum shaft that you can bend to your desired position with a little bit of elbow grease. It does not come with a base plate, so if you need one, you’ll have to purchase it separately.

Includes a protective cover
Mounting does not require drilling
Rod may loosen over time

6. Brocraft Universal

As long as a stable surface is available, you can install the Brocraft Universal (around $39) to just about any location on your fishing vessel by tightly securing the mounting plate. It’s built with metal and heavy-duty plastic that won’t break down in marine environments.

Works on inflatable boats
Lightweight for portability
Takes up quite a bit of space

7. Ram Rigid

You’ll be able to quickly mount the Ram Rigid (around $43) without too much effort, which is especially helpful when you plan to move it from one boat to another somewhat frequently. Its aluminum rod is firm and simple to adjust as needed.
