Lowrance uses preloaded C-MAP charts that not only make navigation safer, but also make it easier for you to find areas to fish. Quickly pinpoint areas fish like to hide, like ditches, drops-offs, points, submerged roads, and spend less time looking for a fishing spot and more time fishing.

Lowrance fishfinder/chartplotter displays come with built-in sonar (fishfinding) and navigation (chartplotter or GPS Plotter) capability. Most displays come with a transducer and preloaded mapping, but some are available without a transducer and with basic, non-mapping GPS plotter navigation.

The Lowrance Elite-5 is a combination chartplotter fishfinder that couples a 5-inch display screen, 16-channel GPS with internal antenna, and 500-watt sounder into a single unit.

Lowrance has been a leader in marine electronics since it invented the first consumer sonar device in 1957 -- The Little Green Box. In the years since, Lowrance has never wavered from its purpose to push the envelope of innovative performance to help anglers find and catch more fish.

A fish finder helps detect a fish school and provides various underwater information, such as water depth, distribution of fish school, and the condition of the seabed by transmitting ultrasonic waves into the sea and receiving its reflection.

sonar fish-finder, also called Netsonde, in commercial fishing, high-frequency sonar device for locating schools of fish. It transmits sound waves downward and receives echoes from the bottom of the sea, or from intervening schools of fish, also indicating distance from ship to fish.

Lowrance is a manufacturer of consumer sonar and GPS receivers, as well as digital mapping systems. Headquartered in Tulsa, Oklahoma, with production facilities in Ensenada, Mexico, Lowrance employs approximately 1,000 people.

All Elite-5 DSI fishfinder/chartplotter models feature a built-in 16-channel GPS +WAAS antenna for out-of-the-box, plug-and-play navigation, along with an external antenna option.

Down through the water column. When. This signal comes into contact with fish structure. And the bottom surface. Its reflected back toward the transducer.

Fish finders detect the presence of fish primarily by detecting the air in their swim bladders. The air conserved in the swim bladder changes the sound path and reflects energy back. The fish finder detects this reflected energy and converts it into fish images on the screen.

Harvesting of aquatic resources and production is done either in the wild (capture fisheries) or in controlled environments (aquaculture). Both use a large variety of technologies - from artisanal to highly-industrial - encompassing vessels and equipment as well as fishing gears and methods.

A fish finder consists of three main parts - a transducer, a processor, and a display screen (the processor and display screen are usually combined). The transducer sends and receives sonar pulses underwater. It contains piezoelectric crystals and vibrates at a specific frequency.
