Conclusion

There are a few different types of depth finders on the market, but the most popular and affordable type is the fish finder. Fish finders use sonar to detect fish in the water, and they can be very accurate.

However, they are not perfect, and sometimes they may not be able to detect fish that are close to the bottom or in murky water. Depth finders can be a great tool for anglers, but they should not be relied on completely.

Sometimes, the best way to find fish is just to get out there and start fishing!.
