Page 18: Functional Principles
Simrad SP70 Functional principles When the Omni beam is tilted, the total beam picture can be compared with folding an umbrella, which means that all beams in 360_ around the vessel have the same tilt angle. Figure 3 - Omni beam In the standard version, the beam can be tilted from +10_ up, to - 60_ down.
Page 19 System description Figure 4 - Vertical slice Figure 5 - OMNI / vertical combination For the optional 90_ tilt version, the OMNI/vertical combination is used in several display modes to give the best situation overview for both purse seiners and trawlers. In these presentations the seine net and the trawl can be seen in relation to the vessel, the school of fish and the bottom.
Page 20: Reception
Simrad SP70 Reception A great effort has been made to reduce unwanted noise to get a clean and stable echo presentation. To achieve this goal the sonar receiver has the following filtering possibilities: FM CORRELATION FILTER In addition to the traditional single frequency transmitting method, the SP70 sonar is equipped with an FM correlation mode.
Page 21: Transmission
• Simrad echo sounder (EQ, ES and EK series). Gives depth readout in the menu and a bottom plot on the catch data page. • Simrad PI30 Purse Seine System. Gives the net depth in digits and bars on the vertical views.
Page 22: Modes Of Operation
Simrad SP70 2 MODES OF OPERATION General This chapter describes the SP70 modes. The various modes represent the graphical presentation of sonar data. Several display modes is generated for giving the best possible overview presentation and a flexible choice for a large range of user applications.
Page 23 Modes of operation In most display modes with multiple views, the size of each view can easily be modified by moving the boundary line between the views: Locate the cursor on the boundary line, press Select and move the cursor with the Select button in the inner position. When the Select button is released, the boundary line will be located to the actual cursor position.
Page 24: Bow Up
Simrad SP70 Bow Up Figure 6 - Bow up When the Bow Up mode is selected the vessel symbol is stationary on the screen, with the bow pointing upwards. The echo presentation covers 360° around the vessel, and all echoes will be updated for each ping.
Page 25: North Up
Modes of operation North Up Figure 7 - North up When the North Up mode is selected, true north is always up on the screen and the vessel symbol is stationary with the bow pointing in the direction of the course. The movement of the echoes across the screen will be a combination of the vessel course and speed, and the targets own movement.

Page 27: 180_ / Audio
Modes of operation 180° / Audio Figure 9 - 180° / Audio When the 180° / Audio mode is selected, the upper half of the screen shows a 180° bow up presentation, while the lower part is used for a recording of the audio channel. The audio channel is shown with a continuous white line in the horizontal picture, and can be trained in any direction.
Page 28: 180_ / Echosounder (Option)
Simrad SP70 180° / Echosounder (Option) Figure 10 - 180° / Echo sounder When the 180° / Echosounder mode is selected, the upper half of the screen shows a 180° bow up presentation, while the lower part is used for an echo sounder recording. That means that the sonar acts alternately as a normal sonar and an echo sounder for each second transmission.
Page 29: 180_ / Vertical (Option)
Modes of operation 180° / Vertical (Option) Figure 11 - 180° / Vertical (option) When the 180° / Vertical mode is selected, the upper half of the screen shows a 180° bow up presentation, while the lower part is used for a vertical slice presentation. In that way an echo can simultaneously be presented in both horizontal and vertical dimensions.
Page 30 Simrad SP70 In addition to the normal tilt indicator, the tilt angle is also shown in the vertical slice by a continuous white line. In that way, it is easy to select the optimal tilt angle on an echo in the vertical slice, to get the best drawing of the echo in the horizontal presentation.
Page 31: 270_ / Vertical
Modes of operation 270° / Vertical Figure 12 - 270° / Vertical The 270° / Vertical mode is specially made for purse seining, where the vertical half slice is displayed in the lower left corner for normal setting of the net on starboard side. If the net is selected to be set on the port side, the vertical half slice will be displayed in the lower right- hand corner.

Modes of operation 2.10 Omni / Echosounder (Option) Figure 14 - Omni / Echo sounder The Omni / Echosounder mode is also specially made for trawling, but in this mode the trawl- locked vertical slice is replaced by an echo sounder recording. This to ensure a more correct depth indication in case the sonar beam is bent because of temperature layers.

Page 36: 2.13 Dual
Simrad SP70 2.13 Dual Figure 17 - Dual operation The Dual mode is a kind of “two sonars in one” operation, where each presentation part is updated for each second transmission. All settings can be set separately for each presentation part. This makes the dual mode especially useful for optimizing settings by directly comparing the two presentations.
Page 37: Operation
Operation 3 OPERATION Introduction All operation of the sonar is normally made from the Sonar Operating Panel. This section contains a detailed description of the start/stop procedures, the Operating Panel and the menu operation.
