There are many fish finders on the market today, available from reputable companies including Humminbird, Eagle and Lowrance, that are offering some of the most technologically advanced features imaginable. Some of these sturdy fish finders boast large, bright screens, come in a variety of strengths and can take a beating in tough conditions. In this article, we’ll explain how the these devices work and help you decide if a new high tech model is the right device to have aboard your boat.
These new generation fish finders are very easy to use. Start by mounting the unit on your boat using the mounting kit that came with the unit. The three most common places to mount fish finders are on the bow, stern or near the steering wheel. The device that actually sends a sonar signal into the water and relays information to the fish finder is the transducer. Some units come with transducers, while others require a separate purchase. Mount the transducer on the back of the boat so that it’s underwater. Finally, connect the transducer wire to the fish finder.
Installing your transducer correctly is critical to the operation of your fish locator. Most of the permanent-mount transducers are designed for high-speed operations. For the best results, the transducer should be placed where a smooth, undisturbed flow of water will pass across the face of the transducer at all boat speeds. Make certain that the chosen location doesn’t interfere with the boat’s trailer.
The transducer is the main component of all makes and models of these devices. It is what emits the sonar signal that evaluates what is under the boat. Generally, high frequency sonar units provide the best resolution and definition of structure and targets. The transducer’s cone angle determines the coverage area. Wide cone angles are suitable for shallow to medium depths, while narrow angles operate better in deeper waters. The depth capability of your sonar units depends on its transmitter power, receiver, sensitivity and frequency, transducer and transducer installation. Other things that effect depth finder capabilities include water conditions and type, and bottom conditions.
The technology of fish finders is always moving forward. You can get constant satellite updates with a GPS receiver and there are electronic probes available with independent microprocessors that will feed back additional data to your monitor. The devices are also available with large screen monochrome monitors. Most of these models come with 200 kHz transducers and thermal scanners. Of course, technology comes with a price, so be prudent about how much you’re willing to spend. Once you have found a device that fits your needs, it will be the best fishing buddy you’ve ever had.
If you want to increase your odds of catching fish, you should consider investing in a fish finder. But how do you know if the Furuno FCV 295 10.4″ fish finder is better than the Garmin 140, for example? You need to read some fish finder reviews to help you decide on the right model for your needs.
