Before you mount it anywhere on your boat, the first step you should take is registering your fish finder. You should do this immediately after unboxing your handy new device because this allows you to activate your warranty in case you encounter any issues.



Registering your new fish finder with the manufacturer also allows them to contact you whenever there are updates or crucial information regarding your device.

Compared to the technology used in previous models, today’s fish finders are more advanced and sophisticated. They often have built-in software that allows your device to function more effectively and provide more accurate results.



With that said, after you have unboxed and registered your new device, the next step you should take in the process of depth sounder installation is to update its software. Making sure that everything is up-to-date will ensure its smooth operation while out in the water.

Once everything is in order, you can now select the best location for installing a fish finder on a kayak or boat. This is perhaps the most crucial aspect of the installation process because its location can determine its functionality.



After all, you wouldn’t want to go through the trouble of following all the Garmin Striker 4 Transducer installation instructions only to find that you picked the wrong spot to mount it. 

With that said, to find the best location, make sure it’s in a spot where you can easily reach it without obstructing your visibility or other essential functions. Moreover, if you need it to turn around 180 degrees, ensure that your mounting location has enough room for it.

Once you know where you want to put your new fish finder, the next step would be to ensure that it actually reaches your chosen power supply. Moreover, make sure that the power source will provide enough power for your device.



Aside from this, you should also make sure to avoid experiencing interferences for more accurate results. For this, you can install a ferrite ring, especially if you’re using a trolling motor as a power source.

Your device’s transducer plays a significant role in getting the best images, so you will need to find the best location and angle for its installation. Make sure to identify where’s the best place for your specific kind of boat.



After all, improper installation of the transducer will result in poor images and inaccuracy in what you see on the digital screen of your fish finder. 

Installing the transducer on the boat’s hull is a crucial part of the fish finder installation process, but doing so without the transducer mounting board will result in a poorly performing sonar device. 



Still, this will depend on the type of hull you have, so check out the following for installation on different hull types.

When installing your transducer on aluminum hulls, make sure it’s nowhere near welded or riveted joints. This is because it’ll form air bubbles, significantly reducing the quality of your images.

For fiberglass hulls, make sure to install it on the transom (for smaller units) or the jack plate (for larger ones). Moreover, ensure to avoid obstructions in the surroundings, including speed and temperature sensors. You can add a transducer shield for additional protection.

Running your wires may be the most daunting part of the process, especially since you’re dealing with electrical components and not all boats have the same structure. With that said, it’s best to use a snake for running your wires instead of removing the boat panels.



This can help you pull the wires through without dismantling anything, but you need to make sure that they don’t get caught in the other parts of the boat, especially the motor.

Once you have run the wires, the next step would be to ensure that everything is working correctly. Make sure that all parts are functioning well and you’re getting the best possible performance out of your fish finder.

If everything is working as it should, the next step would be to secure the wires. This means using heat-shrink connectors wherever they’re needed and spraying all connections with a generous amount of corrosion inhibitors. This will help everything become more resistant to corrosion, thereby prolonging its lifespan.

It may be tempting to go out for a test run after installing your new fish finder, but you need to make sure that everything – including the sealants used – cures and dries completely. It usually takes a week to cure entirely, but this will depend on the environmental conditions.

With that said, after giving it enough time to settle, you can go ahead enjoy your new device out in the water.

A fish finder is undoubtedly a handy device for your boat as it can give you valuable information from the comfort of your vessel. Still, the installation process can be tricky, which is why you might find the tips mentioned above helpful.
