761型渔用声纳主要用于围网渔船和拖网渔船。它是一种多波束声纳。该声纳有12个波束可搜索90度以内的扇面目标。它可象雷达一样直观描述观测目标。并可测出渔群的距离和渔群运动的方向。当撒出围网时,该声纳可清楚地示出网和渔群之间的距离。本仪器是一种性能良好的捕鱼工具。
761 fishing sonar is mainly used for seiners and trawlers. It is a multi-beam sonar. The sonar has 12 beams that can search for fan targets within 90 degrees. It can be as intuitive as the radar to describe the observation target. And can measure the distance between fisheries and fisheries movement direction. The sonar clearly shows the distance between the net and the fishing grounds when the fence is sprinkled. This instrument is a good fishing tool.
