In this post, we'll explore some of the best fish finder accessories and add-ons on the market today. From GPS systems to transducers, we'll cover everything you need to know to enhance your fishing experience. So grab your tackle box, slap on some sunscreen, and get ready to reel in the big one!

Fish Finder Transducers

The transducer is the most crucial part of the fish finder. It is the device that sends and receives the sonar signals that locate the fish. A high-quality transducer will give you accurate readings and help you locate fish more efficiently. When choosing a transducer, it's essential to consider the frequency and the cone angle.

Higher frequencies provide better detail but have a narrower cone angle, while lower frequencies have a wider cone angle but less detail. There are several types of transducers available, including:

Thru-hull transducers
Transom mount transducers
Portable transducers

Each type of transducer has its advantages and disadvantages, depending on your fishing needs. Thru-hull transducers are the most permanent and can provide the best performance, while portable transducers are the most flexible and can be easily moved from boat to boat.

GPS Module

A GPS module is an excellent accessory for your fish finder. It allows you to mark fishing spots and navigate to them later. With a GPS module, you can create your own fishing maps and track your movements. This feature is especially helpful when fishing in unfamiliar waters. With GPS mapping, you can easily navigate the water and return to areas where you've had success in the past. Some fish finders even offer detailed charts and maps that can help you find the best fishing spots.


Most fish finders come with a built-in battery, but it's always a good idea to carry a spare battery or a portable power bank. A dead battery can ruin a fishing trip, so it's essential to have a backup power source. Also, make sure to check the battery life of your fish finder before heading out to avoid any inconveniences.

Mounting Systems

A sturdy mounting system is essential to keep your fish finder in place while you're fishing. There are different types of mounting systems available, including flush mount, gimbal mount, and portable mounts. Choose a mounting system that is compatible with your fish finder and the type of boat you're using.

Temperature Sensor

A temperature sensor is an add-on device that measures the temperature of the water. It can help you locate fish more efficiently as different species prefer different water temperatures. With a temperature sensor, you can find the areas with the ideal temperature for your target fish.

Fish Attractants

Fish attractants are substances that mimic the scent of baitfish or other food sources, attracting fish to your bait. There are different types of fish attractants available, including sprays, gels, and scented baits. Fish attractants can significantly increase your chances of catching fish, especially in waters with low fish populations.

Wireless Connectivity

Wireless connectivity is an essential feature in modern fish finders. It allows you to connect your device to other devices such as smartphones, tablets, or laptops. With wireless connectivity, you can transfer data, share fishing spots, and even stream live video.

Fishing Rod Holders

If you're planning to spend a lot of time on the water, fishing rod holders can be a game-changer. These accessories can help you keep your rods organized and secure, allowing you to focus on catching fish. There are several types of fishing rod holders available, including flush mount rod holders, clamp-on rod holders, and adjustable rod holders. Choose the type that works best for your fishing style and boat.

Waterproof Phone Cases

In today's world, it's important to stay connected, even when you're on the water. A waterproof phone case can help protect your phone from water damage while still allowing you to use it for calls, texts, and other important functions. Some phone cases even come with built-in lanyards, so you can keep your phone close at hand while fishing.

Boat Accessories

If you're serious about fishing, you'll want to consider investing in some boat accessories that can make your time on the water more comfortable and productive. Some popular boat accessories include:

Trolling motors
Rod storage
Bimini tops
