These fish finders can range in price from under $100 to several hundred dollars, depending on the brand and features included.

What Type of Fishfinder Should You Buy?
There are many different types of fishfinders available on the market, each with its own unique features and capabilities. When choosing a fish finder, it’s important to consider your specific needs and how you plan to use the device.
One factor to consider is the type of display. Fishfinders come with either a color display or a black-and-white display. Color displays tend to be easier to read and provide more detailed information, but they may be more expensive. Black and white displays are generally less expensive, but they can be harder to read in certain conditions.

You should also consider the type of sonar technology used by the fish finder. There are two main types of sonar: broadband and narrowband.
Broadband sonar provides a wider range of frequencies, making it better for shallow-water fishing, while narrowband sonar provides a narrower range of frequencies, making it better for deep-water fishing.
It’s also a good idea to consider the features and capabilities of the fishfinder, such as GPS, mapping, and the ability to connect to other devices.
Ultimately, the best fishfinder for you will depend on your specific needs and preferences. It may be helpful to read reviews and compare different models to find the one that best meets your needs.
Do fish finders on kayaks work?

Trolling motor transducers are mounted on the trolling motor and use the movement of the trolling motor to create a sonar signal. Both of these options require a power source, such as a battery, to operate the fishfinder.
Portable fishfinders can be mounted on the kayak or used handheld, and they often have a built-in transducer that can be placed in the water.
These fish finders are usually smaller and less expensive than traditional fishfinders and do not require a separate power source.
Regardless of the type of fishfinder you choose, it’s important to make sure it is properly installed and secured on the kayak to ensure accurate readings and prevent damage to the device.
It’s also a good idea to consider the durability and waterproofness of the fishfinder, as it will be exposed to the elements while on the kayak.
