The FLS transducer can be turned to look sideways out from the boat which allows time to become the third dimension. Also, as the vessel moves ahead, a three dimensional view of the seabed is built up. A second transducer and changeover switch may be fitted enabling forward or sidescan mode to be quickly selected. If preferred, a single transducer can be turned to look in the desired direction.
The innovative Sidescan 3D provides coverage of areas up to 150 meters away from the boat and has a maximum depth capability of 75 meters. If your boat is traveling 5 knots, an impressive 11,250 square meters of seabed can be displayed on a lattice grid of 240 points. The Sidescan 3D is unique in its ability to provide a real time 3D picture of the seabed over such a large area. The 240 point lattice is fine enough to show a detailed view of the seabed and structure below your boat.
The EchoPilot Sidescan 3D includes all the functional features of the FLS Gold, like the 150 meter forward view FLS. This feature gives users a choice of 6 ranges from 20 meters to 150 meters ahead, and from 10 meters to 75 meters down. The forward alarm function alarms a section of the screen 2,4,6, or 8 meters below the transducer right up to 150 meters ahead. Units can be changed to feet in the menu. The optional repeater unit is fully equipped and housed in the same case as the master instrument.
This system has a NMEA interface that allows the instrument to accept and display GPS data and also to accept or output speed and depth to other instruments. If speed, trip, and log are required install the optional log transducer, available in paddle wheel or ultrasonic versions. The ultrasonic version has no moving parts to foul or wear. The digital depth is an average of the first one third of the screen, an advantage over ordinary digital echo sounders, which just display historical information.
The included Professional transducer should be installed in sail boats alongside the keel. Single and twin-screw shaft driven boats require a position between the gear box and stern gland. Directly in front of the engines, on stern drive vessels, will provide the most accurate readings.
Keep inboard of the lower spray rail if possible and not down stream of other through hull fittings. Partial heel to port or starboard is acceptable, to a maximum of 5 degrees. In the fore/aft plane the transducer must be vertical. The transducer has a special design that allows it to break off clean and flush with the hull upon impact. The remains of the transducer are still in the skin fitting eliminating water ingress.
