How To Use Lowrance Fish Finder
When shopping online for discount marine electronics, such as a Lowrance fish finder, it helps a lot to understand a bit about the technology you are shopping for. Here is a quick explanation of some of the terms you will encounter. Cone Angle First of all, fishfinders use sonar to probe the depths of the sea or lake bed and determine a picture of what lies beneath the water. When you shine a flashlight into the darkness, the light fans out creating a cone that is narrow at the source and wider at the distant end. Electronics does the same thing. The Cone Angle refers to the spread of the beam at the distant end, so a 90 degree beam offers more coverage than a 20 degree beam. Multi-beam systems, as the name implies, send out more than one sonar beam, cumulatively offering a much wider field of view. The Lowrance HDS-7 Fishfinder and GPS Chartplotter series offer a stunning 120 degree view with superior clarity and magnificent detail.Learn how to use your Lowrance fish finder with Mus...
