FISHING DEVICE CONTAINING UNDERWATER INFORMATION DETECTING SENSOR, AND UNDERWATER INFORMATION DATA STORAGE DEVICE AND UNDERWATER TOPOGRAPHY DISPLAYING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide effective fishing by easily getting underwater information (topography, water temperature, obstacle, water depth, the presence of fish) by a fisherman. SOLUTION: The fishing device 1 containing the underwater information detecting sensor is thrown until an arbitrary point, the underwater information is detected by a sound wave sensor 5, and concurrently the water temperature is detected by a water temperature sensor 4 to be displayed. The topography, the water temperature, the obstacle, the water depth, and the presence of the fish at this place can be got by projecting the underwater information and the water temperature information that are detected by radio communication to a mobile type of underwater information display device, or a display screen of a personal computer, a mobile game machine, or a mobile phone at the hand of the fisherman. The place where fishes are possible to stay is found by changing the place that the fishing device 1 containing the underwater information detecting sensor is thrown.
