ⓘConsidering that fish detection is handled by software algorithms, Fish Icons function can sometimes make
mistakes in fish detection. We recommend turning off Fish Icons and using the second method described in this
manual.
ⓘ Please note that it is impossible to determine the exact size of the fish using any kind of sonar technology - this is
related to how all sonars work and ultra-sound physics. So, you should look at different size of fish icons as an
approximate evaluation of the size of the fish, but not as exact measurement. It is impossible to say that Big fish
icon means that the fish underneath is more than 20 or 35 cm long. But when you see a big fish icon - there is a
very good chance that the fish is actually big.
2. Detailed sonar screen mode (Fish icons OFF - recommended)
Recommended option is to disable Fish icons and look at the real sonar readings, which is a more advanced
method, but more accurate at the same. This is a recommended way of locating fish. If you will turn Fish Icons off,
you'll see that fish in sonar readings are displayed like arches or lines. The thickness of those lines/arches is the
indication of how big the fish is.
Recommended settings:
Sonar display: Detailed (Raw)
Wide beam (47°/55°) is good for quickly scanning larger areas and getting general information on fishes,
depth and bottom structure, but the accuracy and detail will be lower. You will not be able to accurately
determine the size the fish using Wide beam, but due to a large area covered by the beam, you'll be able to
locate the presence of fishes faster (for example, if you're looking for schools of bait fish).
Note: Wide beams are not suited for shallow water scanning. If you are scanning waters shallower than 2-5 meters
(7-16 ft), we recommend switching to Narrow beam.
Narrow or Middle beam (7°/15°/20°) is much more accurate when determining the size of the fish, so if
