Fishing has come a long way since trial and error. Fish finders tend to come in two different display types. CRTs are best used for commercial fishermen and deep sea fishermen. You can purchase fish finders that have colored screens or black and white screens.

If you find yourself fishing a lot, then you are probably more willing to spend money on a high-quality fish finder. Companies like Garmin and Eagle create high-quality fish finders that utilize waterproof LCD screens and offer both color and black and white.

You will not see specific fish, but rather areas fish may congregate, so depth can be important. Low-frequency is most useful in deep water with a wide range, high-frequency for a narrowed spot with more detail.
