kayak fish finder mount

Kayak fishing enthusiasts have many mounting options for their fishfinder. The most common types of mounts are flush-mounted, transom-mounted, and track-mounted. Installation is a simple process of securing the mount to the kayak, connecting the necessary cables, and ensuring the fish finder is securely in place.

To customize a setup, kayak anglers can also choose from a wide range of mounting accessories, such as power cables, transducer arms, and specialized hardware.

Kayak Fish Finder Mount Types

There are different ways to attach a fish finder to a kayak. Here are some popular choices:

This type of mount for a transducer has an arm that extends into the water and can be moved. The transducer is at the end of the arm. It sends and receives sonar signals. It makes it easy to move and adjust the transducer for the best sonar performance.

  • Track Mount: Many kayaks have built-in tracks that can be used to attach different accessories. Track mounts for fish finders can slide along these tracks, giving you options for where to put the fish finder and making it easy to move it or take it off when you need to.
  • Suction Cup Mount: With a suction cup mount, the fish finder display unit is stuck to the surface of the kayak. They are easy to put up and take down, which gives you options for where to mount them. But they may not be as safe as other types of mounts, so make sure you have a strong connection before you go out on the water.
  • RAM Mount: RAM mounts are popular because they are flexible and last a long time. They have a ball-and-socket system that lets the position and angle be changed. RAM mounts usually need extra adapters or mounting plates that are made for the model of fish finder, but they are strong and can be made to fit your needs.
  • DIY Mounts: Some kayakers like to make their own mounts out of things like PVC pipes, brackets, or straps. DIY mounts give you more freedom in design and can be changed to fit different kayak models and your own tastes.

Kayak Fish Finder Mount Accessories

  • Transducer Mounting Kit: This kit includes hardware and adhesive to secure the transducer to your kayak. Transom, through-hull, and other mounting methods may be available.
  • Power Supply and Battery Box: You’ll need these to power your fish finder. These accessories provide reliable power and protect the battery from water.
  • Transducer Arm Extension: Add an extension piece to extend your transducer arm mount. This allows deeper water clearance or kayak setup adjustments.
  • Sun Visor or Hood: In bright sunlight, a sun visor or hood over your fishfinder display can reduce glare and improve visibility.
  • Cable Management Kit: Organized and protected cables improve functionality and safety. Clips, ties, and mounts in a cable management kit neatly route fish finder cables along your kayak.
  • Screen Protector: Protect your fish finder’s display from scratches, smudges, and water. It improves visibility and device longevity.
  • Mounting Plate or Adapter: Some fish finders and mounts require a specific mounting plate or adapter for compatibility and secure attachment.
  • A quick-release mount lets you remove and reattach your fishfinder display. It’s useful for storing and moving fish finders between kayaks.
  • Arm extensions, double socket arms, and ball adapters can help you fine-tune your fish finder position with a RAM mount system.
  • Waterproof Bag or Cover: Protect your fish finder from water, dust, and other elements when not in use. Waterproof bags or covers protect them during transport and storage.


Finding the best depth finders for kayaks is a daunting task. There are many different models and brands on the market, with different features and prices. Kayak anglers should consider their budget and fishing needs when searching for the best depth finder for their kayak.

The Humminbird and Garmin brands have some of the best and most versatile models, and their fishfinders are easy to install and use. For those on a tight budget, there are many reliable budget options available as well. No matter what type of fish finder is chosen, it is sure to make fishing from a kayak more enjoyable and successful.

kayak fish finder setup

The setup of a kayak fish finder requires careful consideration of a number of important components. Firstly, one must determine the ideal mounting option that allows the device to remain secure, even in choppy waters. Secondly, the selection of the transducer is essential, as it will determine the accuracy of the readings. Finally, ensuring a reliable power source is a must for the device to function properly.

Mounting Options

When it comes to mounting a fish finder on a kayak, there are several different options available. The most popular option is to mount the fishfinder directly to the kayak using bolts and nuts. This method provides a secure and stable base for the fishfinder, making it unlikely to move or shift while in use.

This is ideal for areas with rough waters or large waves, as the fish finder is more likely to remain in place regardless of how much the kayak is rocked. Finally, an easy and convenient option is to simply use a suction cup mount. This method requires no installation and can be quickly and easily attached to the kayak.

It offers a secure hold, allowing the fish finder to remain in place even in choppy waters. However, because the suction cup does not provide as much stability as the other mounting options, it is best used for short trips and in calm waters.
