A fathometer used to measure ocean depth.

1fathon = 6feets.

Fathometer is a device which used to find the depth of water and know the underwater species. Also, it is unit of depth 1fartom=6feet.

Hello,

The correct answer is A) Earthquake.

Although meter and fathoms can converse why depth is not expressed in meter instead of fathoms?

@Kanhaiya.

1 fathom = 6 feet and 1.8288 meters.

Kanhaiya said:   7 years ago
Is some conversion fathom with meter?

Since Fathom is the unit used to measure the depth of ocean so obvious that Fathometer is the device to do so.

In this fathometer used in submarine it work on ocean dept.

How is this possible?

In this sound go on the dept same sound come on the return (reflected) and it used to can see the ocean depth its mechanism of fathometer.

The depth of the ocean is measured in fathoms (unit of depth) and the instrument which is used to measure the depth of ocean is called fathometer.

A fishfinder is a type of fathometer, both being specialized types of echo sounding systems, a type of Active SONAR. ('Sounding' is the measurement of water depth, a historical nautical term of very long usage.) The fishfinder 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.

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. Thus today, both have merged, especially with the advent of computer interfaced multipurpose fishfinders combining GPS technology, digital chart-plotting, perhaps radar and electronic compass displays in the same affordable sporting unit
