How To Install Fish Finder Transducer – Fishing tips for 2022

How To Install Fish Finder Transducer
How to install fish finder transducer is a frequently asked question among anglers from across the globe.
A fishfinder is a handy tool that can detect fish underwater using SONAR technology. It uses a screen to display the location of fishes.
The technology was first introduced to the world in the 90s and has seen continuous improvement after that. In this article, we will discuss how to install a fishfinder transducer in detail.
Before jumpting into the installation procedure, let us discuss how fish finders work.

How does a transducer work for a fish finder?

A fish finder uses a screen and a transmitter to display the location of fishes underwater.
You need to set up a transmitter underneath your boat. That transmitter will send a signal throughout the tides. This situation is where SONAR technology comes into play.
SONAR utilizes the reflected waves to determine the fish’s location. It analyzes how the waves are reflected and then uses that data to display where the fishes are.
Moreover, it makes sure that you are not getting any false information by separately displaying the waves reflected by the fishes compared to other reflections.
The reflection of sound is quite different when there are fish from when there are not. It uses a variety of symbols to display anything other than a fish.
If there are any fishes underwater, the display shows fish icons or symbols to let you know their location.
Now that you know how a fish finder works, it is time to tell about a transducer’s mounting styles.

Transducer mounting styles

All the Transducer works similarly, but you need to mount it differently depending on the scenarios you will use.
These are the standard transducer mounting styles.

Transom-mount

This mounting style is ideal for smaller boats. Transom mount is applicable for vessel made out of any materials, and even aluminum made ones.
These transducers are comparatively smaller and require only 600W of power to operate. This Transducer is enough for regular usages and is also very versatile.
But keep in mind that you will need to use a kickup bracket for installing a transom transducer. This bracket ensures that the Transducer does not break if it hits an object or gets hit while moving the boat.

Thru-hull

This Transducer is suitable for bigger boats. You have to make a hole in the hull to install this. It uses a high-performance-fairing for mounting.
This mounting style helps the Transducer be parallel to the water and maximize the bottom area’s energy. Thru-hull can be of two kinds.
Thru-hull transducers are robust and require around 2 kilowatts of energy to operate. You can use this Transducer for professional purposes, and they can serve on any boats, but you need to ensure that you have the correct model for it.

In-hull

This type of Transducer is suitable for fast-paced vessels because it does not interfere with the boat’s movement.
Well, it is attached to the ship in a way that helps it to navigate the location of the fishes even at high speeds. They are straightforward to maintain and easily detachable in case you need it.
But keep in mind that these transducers are comparatively more significant than others and require more installation space.

How to install Fish Finder Transducer

A Fishfinder device installation may seem very dreadful, but it isn’t as hard as it looks. Whether you be a casual fisherman or a weekend cruiser, nothing gets as convenient and useful as this.
In this guide, we are focusing on mounting the binnacle mount; it uses the Transcom mounted transducers mostly. It can be done quickly as a DIY.
Let’s dive right into the installation process, shall we?

Step 1

At first, we will have to build up the connection layout. To do so, we need a power connection. A fishfinder operates through an electrical power source.
One positive cable and one negative cable runs into the box of fuses of the vessel. To relay the SONAR information, another connection comes out from the Fish-Finder and goes into the Transducer.
The installation initially requires mainly two of these connections, but another connection could be connected to a networking device. If these wires are more extended, then they can be tied through cable ties.

Step 2

Now we shall move into the binnacle mount. It is the actual mounting bracket of the Fish-finder device. The binnacle mount needs a station. So, finding a place for the station is required.
We need to place it in such a way so that the helm is closer to it, and you can use it to steer. You need to place it as high as your chest. If not, then it might be inconvenient to use, it might also hamper vision.
You should place it so that it can be tilted easily or rotated in a particular viewing spot easily without any obstruction.
The binnacle mount should be placed in the selected position, and then the points where you will drill the holes should be marked.
We can finally set the screws now. We have to draw one more spot for the wires’ exit point, and it needs to be larger so that clump of cables can go between them.
We need to make sure that the cables don’t get twisted or bent unnaturally. Also, we need some sealant for shooting on each of the holes and take out the wires’ clump, connecting the fish finder.
On installation of the fishfinder mount, we need to screw them inside along with the bolts of stainless steel. For a perfect fitting, we need to fasten every bolt with an airplane nut and a stainless-steel cleaner.
By squirting more sealant on the bolts, we can ensure the complete sealing of them against humidity. Next, the wires must be attached with the plug that is designated as the head fishfinder.
You must place the base of the binnacle mount on the plug head. We need to stick duct tape around the wire gap beneath the region of mounting and make a hole.
Some silicone sealants can be pored down around the surface. The fishfinder can be fixed on it if the mount is a quick-release type one, and then the fishfinder can be fixed on it.
But if it fixed more permanently, then we should put more sealant around the wire hole.

Step 3

We are at that part of the installation we are. We need to fix routing the energy wires. Cabling any structure has its whole chapter. In this case, we can use a cranking battery or fuse blocks.
If we go with the vessel’s cranking battery, it will provide quick bursts of energy that the ignition switch need for activation and start the boat’s engine.
Also, it requires continual power, and an isolated trolling machine battery delivers that.
Suppose we go with a fuse. It is safe to use an inline fuse to install a piece of component that is energized by a battery like the fish finder.
In the case of power shortage, the fuse will blow and protect the electronic equipment. If installed, you should install it around the positive head closer to the battery.
Usually, fish finders draw 1.5A and require a 3A fuse. Many boats come a minimum of one fuse barrier or more. You can use it for the distribution of power amongst the numerous circuits of the vessel.

Step 4

Now finally moving on to our most important step, installing the transom mount and Transducer. Almost every fish finder accompanies the Transom mount, and it is among the cheapest alternatives available.
In less than 30mph, at such a lower speed, transom mounts do well for boats smaller than 30 feet. You should place it so that the Transducer submerges into the water while the Transducer needs to be kept parallel.
For finding the correct spot, we can search beneath the transom. You should position the mount in such a way that it remains far from the propeller.
After locating the area, we need to hold the bracket and transom together and then tighten the support through marking the holes and drilling them. Again, we will squirt silicone sealants to secure it.
After fixing the support, we need to position it so that the Transducer remains perfectly horizontal towards the ground. We need to very careful so that the moisture doesn’t enter the vessel.

Step 5

It takes at least four days for the sealants for drying and sealing out the gaps, so we need to be extra careful. If all the steps are followed step by step, we should get the signals immediately after the sealants are dried.
If we do not get the alerts, then we need to check whether the Transducer isn’t reaching underwater or not.
And there you have your very own fishfinder! Grab your bait and beer and sail off to the sea!

Conclusion:

As you can see, installing a fishfinder transducer is not that hard if you know how to install fish finder transducer correctly.
