Scotty transducer mounting arm for kayak & SUP — Black, telescoping 11.5–18in with 360° swivel and slip discs

The Scotty #140 is a corrosion-resistant, telescoping transducer mounting arm that fits all Scotty post mounts and includes slip discs for micro-adjustment.

Designed specifically for kayak and stand-up paddleboard anglers, the Scotty #140 transducer arm provides a compact, adjustable way to carry and position a fishfinder transducer while transporting or fishing. Made from high-strength composite material, this arm resists corrosion in freshwater and saltwater environments, telescopes for flexible reach, and swivels a full 360° so you can stow or deploy the transducer quickly.

How does the #140 make installing a transducer easier for kayaks and SUPs?

The #140 mounts to any Scotty post or rod-holder-compatible mount, so you avoid drilling or permanent modifications to your hull. Its included 241L locking combination side/deck mount and Scotty post simplify attachment, and the telescoping feature lets you set the exact extension needed for clear sonar readings.

• Includes 241L locking side/deck mount and Scotty post for simple installation
• Telescopes from 11.5" to 18" to suit different transducer positions
• No permanent hull modifications required when paired with compatible Scotty mounts

What adjustment options does this arm offer while you're on the water?

The arm swivels a full 360° so you can pivot the transducer for transport or to change scan angle without removing the unit. The included 415 slip disc allows micro adjustments, giving you fine-tune control over tilt and alignment to improve sonar clarity and reduce turbulence noise.

• 360° swivel for rapid stow/deploy and directional changes
• 415 slip disc included for micro-adjustments and precise tilt control
• Secure locking mount prevents unwanted rotation during transport

How durable and low-maintenance is the Scotty #140 for saltwater use?

Constructed from high-strength composite materials, the #140 resists corrosion and stands up to repeated exposure to spray and sun. Its design minimizes metal parts that corrode, reducing maintenance and extending service life so you spend more time fishing and less time repairing gear.

• High-strength composite construction resists corrosion in marine environments
• Minimal metal hardware reduces maintenance needs
• Built for years of regular use on kayaks, SUPs, and small boats

Will the #140 fit my existing Scotty mounts and transducer?

The Scotty #140 is built to integrate with all Scotty post mounts and the included Scotty post fits standard Scotty rod-holder mounts. The arm is a universal-style mounting solution for most transducers, but note the transducer itself is not included—verify your transducer's clamp or bracket compatibility before purchase.

• Fits all Scotty post mounts and rod-holder-compatible mounting systems
• Transducer not included — verify clamp/bracket compatibility with your unit
• Works with side or deck mounting via the included 241L lock mount

Who is this for: The Scotty #140 is ideal for kayak and SUP anglers, small-boat fishers, and anyone using Scotty mounting systems who needs a durable, adjustable transducer arm that stows compactly for transport. If you want a corrosion-resistant, telescoping solution that integrates with existing Scotty posts and gives precise alignment through slip discs and a full swivel, this arm provides a practical, low-maintenance option for on-water sonar deployment.
