1. **Standalone Fish Finders**: These are dedicated devices that focus solely on providing sonar readings to locate fish. They come with their own display and are typically portable, making them great for ice fishing or small boats.
2. **Combo Units**: These devices combine a fish finder with a GPS chart plotter. This is particularly useful for anglers who want to navigate and mark waypoints while also locating fish. They are ideal for larger boats and serious anglers who fish in various locations.
3. **Smartphone Fish Finders**: These are compact devices that connect to your smartphone via Bluetooth or Wi-Fi. They send sonar readings to an app on your phone, allowing you to see fish locations and underwater structures right from your mobile device. They are highly portable and convenient for casual fishing trips.
4. **Ice Fishing Fish Finders**: Specifically designed for ice fishing, these units often have features that allow them to function effectively in cold conditions. They usually have a flasher display, which shows real-time fish movement beneath the ice.
5. **Down Imaging and Side Imaging Fish Finders**: These advanced units provide detailed images of the underwater environment. Down imaging shows a detailed view directly below the boat, while side imaging allows you to see structures and fish to the side of the boat. These are great for locating fish-holding structures.
6. **CHIRP Fish Finders**: CHIRP (Compressed High-Intensity Radiated Pulse) technology sends out a continuous range of frequencies, resulting in clearer images and better target separation. This technology is becoming standard in many modern fish finders.
When choosing a fish finder, consider factors such as the type of fishing you do, your budget, and the features that are most important to you. For example, if you often fish in deep waters, a unit with down imaging might be beneficial. If you prefer fishing from a kayak or a small boat, a portable standalone unit could be the best option.
