Thank you for viewing our Duct Seal Ordering Page. Duct seal is the perfect product for securing your transducer inside the kayak hull. This allows you to mount your transducer inside the kayak for "shooting through the hull". The transducer never touches the water, yet it works perfectly. It is the prefect set up for any kayak that does not have an opening in the hull for transducers. (Viking Kayaks allows for transducers to have direct access to the water)

The putty is slightly sticky, non-hardening even after several months, and is water resistant. Kayaking can take you into places larger boats can't go. Sliding the kayak over rocks or when loading or unloading can harm delicate parts. Securing the transducer inside the kayak eliminates the chance of damage to the transducer.

In addition, you eliminate any problems with drag since the transducer is inside instead of being on the outside of the kayak.

The putty comes with no air bubbles. By shaping the putty to form a large patty you can place it inside the kayak at any location you choose. For fishing kayaks, this is inside the forward hatch. The transducer is pushed into the putty and the edges of the putty can be rolled up to further protect the transducer if you choose.

Note: The location of the putty must be on the bottom of the kayak where water is directly on the opposite side. In other words, below the water line on the kayak so the signal is allowed to pass through the kayak and into the water.

Important: As long as there is no air bubbles in the putty the transducer will work perfectly. Air spaces between the transducer and the kayak floor will cause false readings at best or no readings at all.

I  get accurate water temperature readings and accurate depth readings and so will you.

Ordering is easy on our Duct Seal Ordering Page. And remember, for now there is no shipping on orders inside the U.S. and U.S. territories.

Kayak Rigging Tip Fail: Some people have stated they use the duct seal to form a wall around the transducer and fill it up the space with water. They then set the transducer inside in the water. I have actually tried this and it didn't work for me at all. I couldn't get any reading on the fish finder. Plus you have to keep refiling the space with water each time you go out or tip the kayak too far.

Our method of putting the transducer directly into the putty works perfectly and eliminates a lot of maintenance and other problems.

For a recap:

  1. Find a place on the kayak below the waterline.
  2. Form a large hamburger sized patty with the putty.
  3. Press the putty onto the kayak. Make sure there are no bubbles.
  4. Press the transducer in the putty.
  5. You're done. 

Having the Transducer Directly in Water

If you would rather have the transducer directly in water and not use any Duct Seal, there are a couple things you can do. 

  • 1) You can have the transducer drop over the side of the kayak. There are several mounts that allow for this. The problem is that the side mount and transducer causes drag in the water that can slow you down and are always doing correction strokes to keep on target.
  • 2) You can purchase either a Viking GT or Viking Reload. Both the GT and the Reload come with an interchangeable tackle pod that allows the transducer to sit directly in water. The tackle pod is removable and comes out carrying all your electronics with it so they can be stored away from the kayak in a safe location. This is a preferred method since many of the electronics put on kayak are very costly and expensive to replace.
