sonars can be used as detectors on roads...
no sonars areNo they are not, a sonar maps the ocean floor.
It is called "The Sonars"
SONARs
They can confuse and hurt whales and dolphins in the ocean.
Echo is used for instance in sonars to analyze underwater objects or its surface; in music, in small quantities to give a more powerful and surrounding sound, and in computer language to retrieve data from a program.
Submarines have sonars.
A Garmin Sonar is just a specific brand of sonar. Sonars are used primarily for underwater scanning that can detect objects by emitting pulses or "signal waves", and finding the depth of water. Two great sites for finding more about Garmin Sonars are http://garmin.blogs.com/my_weblog/2008/10/an-in-depth-loo.html and http://www.garmin.com/uk/products/marine-products/.
The frequencies on which sonar is used vary widely. Human hearing is usually cited as ranging as from 20 cycles per second (Hertz) to 20,000 cycles per second. There are many sonars that use frequencies in the 20 to 20,000 Hertz range. In general, the sonars that are used for short range underwater applications operate on a slightly higher frequency than those that are designed to look over long distances. But there are a lot of sonars which use frequencies far outside the range of human hearing. Medical imaging is the most popular use of sonar. The range of frequencies used by these devices range from 2 million cycles per second to 18 million cycles per second. These frequencies are far above what humans can hear.

The technology for sailing is electronic sonars, solar panel boats, radars, and computer guidance, as well as sattelite connected devices.
Maps are a common tool of the geographer, as they provide visual representations of geographic features, spatial relationships, and patterns on the Earth's surface. Maps help geographers analyze, interpret, and communicate information about the physical and cultural landscape.
