Abstract

A fish depth monitor is a device that can display first water depth data that indicates the location of terminal tackle that is engaged on fishing line reeled out from a spool, and second water depth data that indicates the location of the bottom of a fishing location transmitted from a fish finder, and includes a case, first and second reception portions, a display unit, and a control unit. The first and second reception portions receive the first water depth data from an electric driven reel and the second water depth data from the fish finder. The control unit graphically displays the received first and second water depth data in positions that correspond to the water depth on the display unit. It is possible to intuitively determine the positional relationship between the location of the terminal tackle and the location of the bottom.

Claims

1. A fishing data display device adapted to communicate with a fish finder and be operatively coupled to a fishing reel, a fishing line with a terminal tackle being adapted to be reeled out from a spool of the fishing reel, the fishing data display device comprising:

a case;

a first reception portion that is arranged in the case and is configured to receive from the fishing reel first water depth data that indicates a location of the terminal tackle;

a second reception portion that is arranged in the case and is configured to receive from the fish finder second water depth data that indicates a location of a bottom of a fishing location;

a display unit arranged in the case so as to be visible from an exterior; and

a control unit operatively coupled to the first and second reception portions and the display unit, the control unit being configured to graphically display the first and second water depth data on the display unit, so as to show a positional relationship of the terminal tackle and the bottom of the fishing location.

2. The fishing data display device set forth in claim 1, wherein

the second reception portion is further configured to receive from the fish finder third water depth data that indicates a location at which fish are gathered;

and

the control unit is further configured to graphically display the first and second water depth data as well as the third water depth data on the display unit, so as to show a positional relationship of the terminal tackle, the bottom of the fishing location, and the fish location.

3. The fishing data display device set forth in claim 1, wherein

the control unit is further configured to display at least one of the first and second water depth data as a numerical value on the display unit.

4. The fishing data display device set forth in claim 2, wherein

the control unit is further configured to display the first, second and third water depth data on the display unit chronologically and graphically.

5. The fishing data display device set forth in claim 1, wherein

the control unit is further configured to correct the first water depth data based on the second water depth data and obtain corrected first water depth data, and

the control unit is further configured to display the corrected first water depth data on the display unit.

6. The fishing data display device set forth in claim 1, wherein

the case is arranged on the fishing reel.

7. The fishing data display device set forth in claim 1, wherein

the case is arranged separately from the fishing reel, and

the fishing reel is adapted to transmit the first water depth data to the fishing data display device.

8. The fishing data display device set forth in claim 5, wherein;

the control unit is further configured to graphically display the corrected first water depth data on the display unit.

9. The fishing data display device set forth in claim 8, wherein

the corrected first water depth data is obtained by first calculating a correction coefficient which is obtained by dividing the second water depth data with the first water depth data, and then multiplying the correction coefficient by the first water depth data.

10. The fishing data display device set forth in claim 8, wherein

the control unit is configured to assume a position correction mode and to obtain the corrected first water depth data when the control unit is in the position correction mode.

11. The fishing data display device set forth in claim 5, further comprising

an operation key unit that a fisherman is adapted to operate,

the control unit being configured to assume the position correction mode when the fisherman operates the operation key unit and sets the position correction mode.

12. The fishing data display device set forth in claim 2, wherein

the display unit is configured to assume one of a standard display mode and an enlarged display mode, and

the control unit is configured to display each of the first, second and third water depth data in one of the standard display mode and the enlarged display mode so as to show a positional relationship of the terminal tackle, the bottom of the fishing location, and the fish location, and is further configured to switch the display mode in which any of the first, second and third water depth data is displayed.

13. The fishing data display device set forth in claim 12, further comprising:

an operation key unit that a fisherman is adapted to operate,

the control unit being configured to switch the display mode between the standard mode and the enlarged display mode when the fisherman operates the operation key unit to request a mode switch.

14. The fishing data display device set forth in claim 12, wherein

the control unit being configured to switch the display mode between the standard mode and the enlarged display mode based on the second water depth data obtained from the fish finder.

15. The fishing data display device set forth in claim 12, wherein

the control unit is further configured to display the first, second and third water depth data on the display unit chronologically and graphically, and

when the display mode is switched to the enlarged display mode, the control unit graphically displays the first water depth data that is in a range between a half a maximum water depth of the second water depth data and the maximum second water depth data.
