Problems solved by technology

But usually sonar is oriented to detect fish in the vertical direction, especially in the sea. The range of sonar fish detection is the full depth, not the specific depth range where the fishing net is located in the water. Fishing is basically invalid information

Abstract

The invention discloses a depth-adjusting self-rotating fish finder, a use method thereof, and a fish-finding array formed thereby. The fish finder comprises a floating cylinder and a probe rod arranged at the bottom of the floating cylinder. A plurality of floating bodies are arranged at equal intervals around the outer circumference of the floating cylinder, and are connected with the floating cylinder through connecting rods. Each floating body is provided with a fan blade. The bottom end of the probe rod is provided with a vortex spring box. A sonar device in the horizontal direction is suspended from the vortex spring box by a suspension line. At least one anchoring counterweight bar is suspended from the bottom of the sonar device by a suspension line. The floating cylinder is provided therein with a controller, a battery and a wireless signal transmitter which are electrically connected. The sonar is electrically connected to the controller.

Description

technical field [0001] The invention relates to a fish finding device, in particular to a depth-adjustable self-rotating fish finder, a use method and a fish finding array composed of the same. Background technique [0002] At present, there are many fish finder products on the market, and their working principle is realized through the principle of sound wave transmission by using sonar positioning technology. After the fish finder emits sound waves, it measures the distance by the time it takes for the sound waves to touch the object and return. Through the reflected sound wave signal, the fish finder can identify the information of the fish. [0003] A common fish finder consists of a probe with a sonar generator placed in the water when in use. The probe is placed on the water, the sonar signal is collected, and then the fish information is obtained through microprocessor calculation and displayed to the user. But usually sonar is oriented to detect fish in the vertica...
