On fish finders with down imaging technology, fish show up as dots rather than arches. This is because down imaging sonar uses a narrower sonar cone, and only shows a small section of what’s under your boat when fishing.

What do fish look like on Garmin side imaging?
What do the numbers on a transducer mean?
This number (or range of numbers) refers to the frequency of the sound waves produced by that particular transducer. As sound waves travel through tissue, some of them are absorbed or attenuated, and some are reflected back to the transducer to produce an image.
What are the brown and blue wires on a Garmin fish finder?
How to Use the Extra Wires on the Power Cable of a Garmin
The Blue wire is used for a NMEA data out connection to another NMEA compatible device.
The Brown wire is used for a NMEA data in connection to receive data from another NMEA compatible device.
How do I read the bottom of my Garmin?
How does Garmin sonar work?
The sonar module calculates data from the transducer to display an image on the chartplotter. CHIRP stands for Compressed High-Intensity Radiated Pulse. CHIRP transducers operate multiple frequencies per ping, sending a continuous sweep from low to high.
Can you see fish on Garmin Clearvu?
Garmin ClearVü scanning sonar gives you a nearly photographic image below your boat. With ClearVü, you clearly see structure, submerged objects, and fish.
Can you see fish on down imaging?
Humminbird Down Imaging uses a razor-thin, high-frequency beam to create picture-like images of structure, vegetation and fish. Down Imaging returns are oriented identically to traditional, down-looking sonar returns—with the most-recent information appearing on the right side of the screen.
Is Garmin Clearvu the same as Down Imaging?
While these products are similar, there is one key difference that makes them quite different. Both are marketed as down-scanning products, but only one of them has an actual down-facing element in its transducer. That makes a big difference where it matters most – on the water.
Can you see fish on side imaging?
View multiple Humminbird sonar and imaging technologies at once for a complete picture. Here, we can see trees, weeds, and fish to the right side of the boat as the depth falls off. Enable range lines to help determine the distance between your boat and fish, structure or weeds.
A fish arch forms as the transducer moves over the fish or as the fish moves through the sonar beam, if you are not moving. In order for the arch to occur, the fish must enter the beam on one side and exit through the opposite side and basically bisect the cone.
Can fish see you fishing?
There is a blind spot to the rear, and the range of binocular vision to the front encompasses only about 30-45 degrees. For this reason, some experienced anglers believe a fish is more likely to spot a lure if it is cast to the fish’s side instead of directly in front of it.
Which is better down imaging or side imaging?
Side imaging is going to be more useful in shallower water or when you are scanning for shallow diving fish, whereas down imaging sonar is going to serve the deeper fisherman who are fishing vertically better.
How far should a transducer be in the water?
The transducer should be even with the bottom of the boat or slightly below the bottom. Leading edge (the edge closest to the transom of the boat). One click too high: the transducer is tilted out of the water and cannot maintain a sonar signal.
What is a disadvantage to the side scan sonar?
– Can be used in very shallow water. – Small objects (dm range) can be detected. Disadvantages: – No penetration below the seabed. – No precise geo-referencing.
How shallow will side imaging work?
Will Side Imaging work well in shallow water? Yes. In as little as two feet of water the Side Imaging units will show great detail of objects 50-75 feet away from the boat.
