Sonar and Transducer Basics | Lowrance USA
Sonar is a technique used to detect water depth and the presence/depth of objects in the water by sending a signal (ping) underwater and then receiving its echo. The echo is created when the original signal bounces off the bottom and objects in the water column between the transducer and the bottom.

Selecting a Sonar Transducer - West Marine
2023年1月6日 · With a focus on transducer mounting styles and available technologies, this article will help you select the right transducer for your boat. The transducer is the heart of a fishfinder system, changing electrical pulses into sound waves or acoustic energy and back again.
Sonar - Wikipedia
A very directional, but low-efficiency, type of sonar (used by fisheries, military, and for port security) makes use of a complex nonlinear feature of water known as non-linear sonar, the virtual transducer being known as a parametric array.

Choosing the right type of Transducer - Raymarine
2022年8月17日 · When choosing a transducer to fit your sonar/fishfinder needs, it’s important to consider the following things, mounting options, materials, display, power, frequency, and cone angles. Each of these variables will help determine which transducer is right for you.
The Panoptix™ PS70 thru-hull transducer is powered by Garmin RapidReturn™ sonar, which gives you live sonar views up to 1,000’ below the surface with 1-kW power output for strong sonar penetration through the water.
Sonar 101 | Simrad USA
To use a dual-channel transducer you need to have two sonar ports (like our NSS range), or one of our Sonar performance modules like the S3100. The way your transducer performs isn’t just down to its power and frequency.
