Be Among Those Who Uses Fish Finders
There are many fish finders on the market but Lowrance fish finders have established their products as being the most technologically advanced devices available. 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 Lowrance works and help you decide if it’s the right device to have aboard your boat.
The Lowrance fishfinder is 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. The device can be operated either manually or automatically and will measure water depth, temperature, and the speed of the boat. On the Lowrance models, a flat line corresponds with a flat bottom. If the line slopes downward, the water is getting deeper. Conversely, if the line angles upward, the water is getting shallower. The icons that represent fish will be in the shape of fish or in the shape of a boomerang depending on which device you have.
If you are considering adding one of the Lowrance fish finders to your fishing gear, then the transducer should be your main concern. A transducer’s cone angle determines its coverage area. The wider the cone angle is, the greater the area that will be covered. Lowrance offers a variety of 200 kHz transducers with either a wide (20°) or narrow (12°) cone angle. The 50 kHz transducers come with a 35° cone angle. The dual-frequency transducers come with both a narrow (12°) 200 kHz and a wide (35°) 50 kHz cone angles. And the dual-search transducers come with both a narrow (12°) 200 kHz and a wide (35°) 83 kHz cone angles. Generally, anglers should use a wide cone angle for fishing shallow to medium depths. The narrow cone penetrates to deeper depths, but shows less fish and structure due to its narrow beam.
Installing your transducer correctly is critical to the operation of your fish locator. Most of the Lowrance 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. Read your owner’s manual carefully before installing the transducer! If you do have problems, then Lowrance offers an excellent technical support system and self service. A plastic transducer is recommended on aluminum or steel-hulled boats to avoid potential electrolysis problems.
The technology of Lowrance 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 Lowrance device that fits your needs, it will be the best fishing buddy you’ve ever had.
