HALF-SUBMERGED RUNNING TYPE FISH FINDER

摘要

PROBLEM TO BE SOLVED: To solve a problem of a fish finder mounted to a ship and capable of searching in the sea only under the ship, which restricts the opportunity to search a shoal of fish and inhibits the search in other places under operation and during the stop of the ship.;SOLUTION: A detecting part of the fish finder is separated from the ship, and a propulsion apparatus is mounted to operate by remote control. Search in the other place can thereby be performed without moving the ship. The finder and a propulsion unit are submerged to constitute a half-submerged type, which permits stable search and motion, hardly influenced by the waves.;COPYRIGHT: (C)2004,JPO
