Perhaps you want to use a depth finder while you are kayaking. If this is something that you are interested in doing, you may want to know how to mount the transducer to the hull of your kayak. Consumers and kayak owners often panic as they believe they will not work for this purpose. However, it only takes a little digging and you can find the answer you are looking for. So, here is what you need to do.
First off, prepare the area of your kayak by cleaning it with rubbing alcohol. What happens is if you are using a fish finder, any dust and particles can cause a disturbance of the image. From there, apply some silicon and simply stick the transducer in it; ensuring no air bubbles get caught inside. This works as long as the kayak is made of plastic as the beam can shoot through the plastic into the water.
