Kayak Fish Finder Install: Fishfinder is a tool that is used by fishermen to locate fishes in the water. It is a very simple tool that helps locate the presence of fish in the water.

It is very useful for you if you run a business involving fishing. You can also use it if you often go on fishing trips as a hobby. 

Although using a fish finder is a piece of cake, there a few things you need to know before using it. I will help you understand how exactly it works and how can you install it. Also, many other things might pique your interest.

Note: There are many sonars in the market, but finding the best sonar fish finder for a kayak is challenging due to many varities and offers. 

Quick Overview

Working Principle Of Kayak Fish Finder Installation

Working with fishfinder appears as a  high-tech process. But truth be told, it has quite an easy functioning. It is based on the principle of reflection of ultrasonic sound waves. It operates on the technology of the SONAR System.

The use of this technology dates back to the 19th century. Since then many advancements have taken place concerning its processing and features.

Fishfinder has a LED or CRT monitor. The location of the fishes is displayed on this monitor.

First, a transmitter is installed on the kayak. It continuously transmits signals which are converted in to sound waves before sending it into the water. The SONAR System exercises in the technique of the Echo to reflect signals to the transmitter.

When the sound wave hits anything in the water, it reflects. On reflecting, it displays the composition, size, and shape of the object it hit. The degree to which it can be interpreted is based on the frequency and power of the signal that is transmitted.

The distance of the object in water can be calculated by knowing the exact speed of the sound wave in water.

To avoid receiving false signals from other insignificant things, reflection due to fishes is illustrated differently. This avoids confusion from signals reflected from seaweeds or corals. The echo varies in magnitude and form in the presence of fishes.

On the fishfinder monitor, the presence of fish is marked using its symbol. This detection process can be repeated up to 40 times per second.

Step By Step Installation of Fish Finder On Kayak

Installation of fishfinder is quite easy if you know how to go about with the procedure. There are many techniques are using which you can install the device. I will show you some of the easiest ways to install your fishfinder.

Firstly you need to know that there are 4 main aspects of the installation of fishfinder transducers. They being:

  • Head Unit placement
  • Transducer placement 
  • Wiring 
  • Battery Setup

Head Unit Placement: Locate the Unit Where You Can Mount Fish Finder

Foremost you need to decide where exactly you want your fishfinder monitor to be. It depends on the type of kayak you use. I use a pedal kayak, so I can install the transducer on the sides of the kayak. Because of this, the monitor is close to the seat. You merely have to drill and fix RAM mount on the side of the kayak.

The main advantage of using a RAM mount is its adjustability and portability. You simply need to fix it on the kayak and tighter the ball mount. The ball mount allows us to rotate and have any position and head angle. Important features also include its compact size and less coverage of space.

If you have a paddle kayak then it is impractical for you to fix your head unit on the side. You will end up smacking your paddle on the unit. I recommend you to install the unit, forward into the dash. In this way, it will be in front and out of your way. If you want images like we used in our post you can check our other site for free indian stock photos

Installation of Transducers:

Of the whole installation process, this is the most complex part. Some manufacturers make it easy for us by providing scuppers. In some kayak, you will find a scupper located in front of the cockpit.

If you follow it down underneath the kayak, you will find a location for installation, pre-drilled, and ready for the mounting transducer. A similar scupper can be found at the rear end. There are some brands such as Hobie which provide skid plate for installation.

2. Transducer Placement: Locate Place in the Kayak to Set Transducer

It is also known as through-hole transducers mount. For this technique, you will need a high-density waterproof foam. I suggest you opt for a fairly thick foam. Place the transducer on the block. Mark the outline of the transducer.

Leave space on all sides to stick it on the boat. Now, cut through the block. Use a sharp knife to do so. Make sure you have a nice and clean cut. See if the transducer fits firmly. Decide where exactly you mount your transducer to be.

I prefer it to be right underneath me. clean the area using sandpaper. Now using silicone sealant like goop. .Stick the block on the designated location. While sticking make sure the transducer is pointed forward. Use enough amount of glue.

Make sure there are no air bubbles. Now place some weight on it and let it dry. It takes about 24 hours to dry off. Now that you are finally done, pour some water into the cut and see if it leaks. Now place the transducer on the water. See that it touches the water surface. And you are done!

       Don’t fix the transducer right at the tip of the kayak as it will sailing and disturb continuity. One setback of this technique is that it does not give accurate temperature reading. Other than this, I find no difference in sonar reading and down imaging.

3. Installing the Transducer on the Kayak

If you want the easiest way out, you can go for the flexible RAM Mount Transducer available in the market. You simply need to attach it to the arm of the kayak.

The mount has a flexible arm. You just have to put the arm with transducer inside water while sailing. You can keep the arm off the water surface to avoid drag.

4. Wiring and Soldering of the Fish Finder

In case of wiring, you need to make sure you keep it off your way. You can stash it up underneath your seat or in the side pockets. Some manufacturers also provide a battery box or compartment to bundle the wiring. For wiring, you can use different wiring kits available.

It comes with different styles, plug adapters, etc. For example, if you are using both transducers and power cord, you will need a double hole system. You can lock a little rubber piece into the gap and create a watertight seal through the hole of your kayak.

5. Battery Setup: Kayak Fish Finder Battery Install

Kayak fishfinder Battery InstallYou always must take your battery power, an SLA (Sealed Lead Acid) battery life. Such a battery works with the protection of the acid being sealed within the plastic instance of the Battery. Since there isn’t any prospect of this acidity being spilt as the kayak floats to the 25, this is a perfect battery to get the kayak.

Check the Capacity and Sizes of the Battery for Proper Installation

Assess the Ability and Collars of this Battery for suitable Setup These batteries can be found in lots of diverse sizes, but probably the many available sizes are 7, 1-2, and 18Ah. Kayakers utilize battery packs for fishfinders.
Battery capacity is measured in Ampere Hours (Ah). An Ah is 1 amp for an hour. Thus a 12Ah battery is capable of supplying 1-2 amps for one hour amp for approximately 1-2 hours but more than that.

A Place for the Battery of the Fish Finder

As an instance, of a FishFinder that is 250mA needs one-quarter of the amp. If you’re planning on fishing for 6 hrs so afterwards you’re going to have to have atleast a 1.5liter battery. Remember, you should never take the Battery. Bearing this in your mind, you might desire to buy a more 3.0Ah or more rated battery.An area for your Battery of this fishfinder search for a location for your battery power within your kayak, keep it from saltwater. Salt-water can short the Battery out if the seawater can rust underwater, and also the battery terminals.

Protecting the Battery

Fixing the Battery, you’re able to protect the Battery using a battery or perhaps even a foam block. Decide on a foam block that is fresh and then indicates the middle of this foam. Slice the foam leaving the inch gap. Paste the foam onto your kayak to help keep it from the saltwater’s human body.

Additionally, remember to take your battery package’s charger. Don’t use a car battery charger or some ordinary since your SLA battery will be damaged.

Note: After Party Clean-up: How to Clean Kayak And Fish Finder After Fishing?

Once you are back from your fishing trip you must clean your kayak. The kayak is exposed to seawater and debris from the sea. If you do not clean your kayak every time you go fishing then it might cause damage to it. The same is the case with your fishfinder transducer.

Don’t Use Hot Water

To clean your kayak, wash it thoroughly with fresh water. Make sure you get rid of all the debris. You can use a soap or a mild detergent if you like. Make sure you clean it up properly. Stack up the kayak upside down to let all the water out properly. 

Check if the Device is Waterproof for Water Cleaning

To clean your transducer you must use a soft cloth. Do not clean it harshly as it might damage the transducer. Make use of sharp objects to get rid of debris tangled in the transducer. Do this carefully.  If you follow all the steps carefully you won’t have a hard time installing and using your fishfinder.
