WMB-160F Multi-beam Fishing System Take away the guess work and see what s REALLY below your boat! Seven Systems in One
2 WMB-160F WMB-160F Screen Shots The WMB-160F is a multi-beam sonar that has been designed to provide users with high defi - nition fi sh and water column targets as well as detailed information about the seafl oor. It uses fi ve viewing modes displayed on four easily selectable screen displays to view the multi-beam data it collects. The screen displays are optimised to view fi sh and water column targets, to profi le the seafl oor, or to provide combinations of water column and seafl oor profi les. The following are a selection of screen shots taken during actual sea expeditions highlighting some of the many functions of the WMB-160F and divided into the following groups: Sonar fish school and water column targets To display fi sh schools and water column targets, the WMB-160F has three viewing modes available. These are: Sonar fish school and water column targets...2 Seafloor profiles...6 Shipwrecks and foreign objects... 11 Combination viewing modes... 15. A 120 port starboard view of the water column that is updated every ping. Single Beam / Triple Beam. This is similar to a traditional sounder, except that the beams can be dynamically adjusted by the user. Fish Overlay. Fish and water column marks (in colours showing depth) are overlaid onto a grey scale 2-D seafl oor contour view. See Figures 1 to 7 for sample screen shots.

6 WMB-160F Seafloor profiles The WMB-160F has a number of viewing modes to show seafl oor profi les. These are: Contour View. Where the seafl oor depth is shown in a 2-D view with depth indicated by colour. The colour scale can be manually adjusted using the Depth Colours box to highlight the required depth. 3-D View. Where the seafl oor is shown in a 3-D view, with depth again shown by colour. This view can be in North up, Course up, or Free rotate. Backscatter Hardness. This is a 2-D contour view where a greyscale is used to show seafl oor hardness changes. Sidescan View. Where both the water column and seafl oor are shown in a waterfall style of display. See Figures 8 to 16 for sample screen shots. Figure 8 Contour Display: The vessel is shown in the middle of the display, the colour range is spread between RED at 11 m and BLUE at 25 m. Any depth outside this range is grey. Range scale = 1,800 m. Depth Colours box for setting depth colours Sand waves ahead of vessel Range Scale Note: The resolution in the screens of Figures 8, 9, and 10 was captured using an attitude sensor on a hydrographic surveying vessel.

Contour Backscatter View Backscatter Gain box provides gain settings to increase or decrease the amount of BLACK and WHITE in both the sidescan view and the contour backscatter view. Soft Areas Hard Areas Figure 12 Sidescan view presented in a waterfall display showing the rocky area to port and starboard of the vessel and in the water column, with a soft area falling off the screen as the vessel moves away from it.

Note the broken bow section and the masts showing clearly as shadow on the port side. Area of soft ground entering screen Sidescan View Full view of wreck Rocky area leaving screen
WMB-160F 11 Shipwrecks and foreign objects Shipwrecks and foreign objects can be shown in both the water column type (sonar, single / triple beam views) and seafl oor profi ling displays (contour, 3-D, sidescan views). Figure 17 Triple beam view of a shipwreck. Note, the wreck is further to port as the echo is brighter, meaning it is stronger.
