A fish finder works as a sonar tool that helps locate fish. Sonar represents sound navigation and ranging. According to different models you choose, the fish finder can be equipped with GPS, ocean radar and compass to help you find direction on the boat or kayak. Fish finders use sound to locate underwater objects. They work by emitting sound pulses and waiting for echoes. The frequencies used vary, from very low (infrasound) to very high (ultrasonic). This is exactly the same way bats hunt in the air.
What is Fish Finder Battery?
According to its name, we can know that fish finder battery work as core heart in fish finder. It plays an important role in Fish finder. In recent years, with the development of lithium battery technology, the safety and reliability of lithium batteries have been greatly improved. More and more Fish Finder manufacturers have directly installed or optional lithium batteries for users at the factory, and users also like to modify their finders after purchasing it. Compared with lead-acid batteries, the weight is smaller and the storage capacity is greater.
Why Choose Lithium Battery For Fish Finder?
Lithium battery due to higher operating voltage, smaller size, lighter weight, higher energy, lower self-discharge, longer cycle life no memory effect, no pollution, is the ideal energy carrier in nowadays. Lithium battery which is used in boat is not only a dependable power source, but it is also a green choice for environment because it is composed of recycle materials. Lithium batery is non-toxic and it will not emit any vapor or fumes. For decades, deep-cycle submerged lead-acid batteries have been the most cost-effective means of powering electrical fish finder. But with the rise of lithium batteries in many high-power applications, many people are now studying the advantages of lithium batteries. Generally speaking, fish finder batteries are mainly divided into lithium batteries and lead-acid batteries. If you’re looking for all the benefits of battery, DNK lithium battery is your perfect choice.
