| | | B3 ESSO SPLIT BEAM | | |
| | | |
| | | The ES60 is the third generation split beam echosounder from Simrad. With the split beam you can determine the size of the fish before you catch it. This is vital for sustainable and profittable fishery. The picture to the right shows the information displayed on a ES60 split beam system. The biomass information tells you the density of the fish concentration, the so called "fuel meter". | | The bargraph is a distribution of the fish sizes shown on the screen, here the majority of the fish is larger than 25cm. The fish plot at the bottom is widely used to detect fish close to the bottom where the depth varies. Sometimes ghost echoes are displayed in the main picture looking like fish, however, if it is not on the fish plot you can be sure it is a ghost echo! | | |

| | | Picture to the right shows a single frequency, split beam configuration. The echogram is showing a good concentration of Cod larger than 32cm at depth down to over 200m. Frequency is 38kHz which is a very good allround frequency for various depth and speices. | | | The bottom expansion shows large concentration very close to the bottom and that the majority of the larger fish is close to the bottom. This is vital information for effecient fishing. The size distribution can be set to any layer of the water colum to target the fish you are looking for. | | |

| | | |
| | | Like the ES60 single beam the split beam systems can also be configured with multipple frequencies. Here a I arge school of herring is shown using 38kHz and 120kHz both running on split beam transducers. The Simrad range of split beam frequencies are: | | 18, 38, 70, 120 and 200kHz. making it the most complete range on the market today. The ES60 can also be configured with a mixture of split beam and single beam frequencies. | | |

| | | Here is another example of the ES60 flexibility, this is the so-called "pelagic setting" where the bottom is of no interest. In order to focus on a specific area it is possible to phase the range to the exact depth desired. Also, the bottom detector can be | | switched of (notice the zero depth read-out) enabeling the echosounder to run on a faster ping rate even at extreme depth. The size distribution is calculating the fish size only within the phased range maximizing your targeted fishing. | | |
