Information about fish finders & GPS Fishing Electronics:
Fish finders come in all shapes and sizes and offer many different types of features. Some of the most popular fish finders include:
- Eagle fish finder
- Lowrance fish finder
- HummingBird fish finder
- Portable fish finder
- Garmin fish finder
- Bottomline fish finder
- Impulse fish finder
- GPS Fish Finder
A fish finder is a type of fathometer, both being specialized types of echo sounding systems, a type of Active SONAR. Fish finders, like the Eagle Fish Finder, uses active sonar to detect fish and ‘the bottom’ and displays them on a graphical display device, generally a LCD or CRT screen. In contrast, the modern fathometer (from fathom plus meter, as in ‘to measure’) is designed specifically to show depth, so may use only a digital display (useless for fish finding) instead of a graphical display, and frequently will have some means of making a permanent recording of soundings (which are merely shown and subsequently electronically discarded in common sporting fishfinder technology) and are always principally instruments of navigation and safety. Lowrance fish finder uses this type of technology.
The distinction is in their main purpose and hence in the features given the system. Both work the same way, and use similar frequencies, and, display type permitting, both can show fish and the bottom. Bottomline fish finders use this type of technology. Thus today, both have merged, especially with the advent of computer interfaced multipurpose GPS fish finders combining GPS technology, digital chart-plotting, perhaps radar and electronic compass displays in the same affordable sporting unit.
The Lowrance Fish Finder is an example of this technology:
