What is DownScan sonar?
Downscan sonar It’s the basic system that all sounders use, it uses a colour representation to show differences in bottom structure and density and objects in the water column including fish. Even though it’s old technology it is still one of the most useful and important functions to have.
Whats the difference between DownScan and sonar?
Regular sonar (2D sonar) sometimes can’t define the details as well as DownScan sonar. DownScan has a very narrow beam front to back and wide beam side to side so you will “see” finer details. The regular, or 2D sonar, tends to blend the returns together because of the wider shape of the beam in all directions.
Is DownScan imaging worth it?
It’s worth it! You can see a ton of stuff with sidescan but downscan gives you more detail of individual objects.
What is Lowrance DownScan imaging?
DownScan Imaging™ – a fishfinding technology that gives anglers photo-like images of rocks, trees and underwater structure – was developed by Lowrance and patented by its parent company Navico®. It is a game-changing technology that provides clear images of structure – the areas where fish like to hide.
What does fish look like on DownScan?
First, fish on DownScan will show up as bright “dots” and will usually be much shorter than the same mark on 2D sonar. The walleye are easy to spot on 2D sonar (I have circled the biggest one in red).
Is chirp better than sonar?
CHIRP fishfinders transmit a longer pulse than traditional sonar, putting more energy into the water column, with a true broadband frequency range of up to 117kHz. A traditional sonar transmits about one percent of the time, but CHIRP sonars transmit ascending pulses that are ten times as long in duration.
What is CHIRP imaging?
CHIRP stands for “Compressed High Intensity Radar Pulse.” That’s a fancy way of saying it can show you fish that other forms of 2D sonar can’t. By covering a wide range of frequencies, CHIRP produces more accurate, more detailed returns of fish, structure and the bottom.
What does a fish look like on DownScan?
First, fish on DownScan will show up as bright “dots” and will usually be much shorter than the same mark on 2D sonar. The brightness of the “dot” is related to the intensity of the return (hard bottom and big fish have higher intensity returns) and results in bigger fish and harder bottom being “brighter”.
Is Clear Vu the same as Down Imaging?
ClearVu is the new name for the fishfinder presentation that was previously called DownVu. ClearVu transducers offer a wider view of what’s under the boat. This wider view will provide more detail of fish and structure beneath the water, but is more limited in depth performance.
