◆ What you can do with the Fishing Navi-kun app

[Part 1. Display detailed ocean floor map】
Using a detailed map of the ocean floor (bottom topographic map) and the GPS function of your smartphone, you can understand the topography of the ocean floor where your boat is currently floating.
It is possible to estimate fishing spots based on the topography of the ocean floor, and in some areas, the locations of roots and rapids that are habitats for fish are also displayed.

*There are free and paid options depending on the map enlargement rate.

[Part 2. Navigation function]
Your location will be displayed on the submarine topographic map, and you can display the direction the boat is heading, the orientation of your smartphone, and the latitude and longitude of your current location.
Additionally, when you start navigating to a registered point, the direction and distance to the point, boat speed, travel time, and arrival time will be displayed.

[Part 3. Register your special fishing points]
You can register points you found on an ocean floor map or secret points that someone told you about as My Points.
If you catch a fish in a new location, register points on the spot! You can return to the same point again at any time.

[Part 4. Record and save the boat's wake]
You can record and save your boat's wake, so you can later check the route you took at sea and the points you were fishing at.
In fact, the boat was blown away by the wind and was off the point! That's obvious at a glance.

[Part 5.　Japanese nationwide pinpoint weather information]
You can check the weather forecast for coastal waters all over Japan, as well as wind and wave forecasts at sea, in a pinpoint area of 2.5km square.

[Part 6. Tide table and fishing prediction]
You can view tide charts (tide graphs) for 699 locations across Japan. You can display the tide table for the location closest to you or any location.
You can also use the ``Big Catch Timetable PLUS'' (charged), which predicts fishing results based on the tides and moon phases in a given location, and is said to be highly accurate.
[Part 7. Recording/editing/managing fishing results]
When you catch a fish, you can create a fishing record and save photos on the spot or after you get home.
The fishing record can also record weather information and tides at the time the fish were caught, which is useful when planning future fishing trips.

[Part 8. Linkage with website]
Fishing Navi-kun allows you to use both the smartphone app and website with one member account.
Information recorded in apps and websites is saved in a member account on the web, and by logging into My Page, you can edit and manage your saved records from any device such as a computer.

※ Note
When using the navigation and track recording functions of the Fishing Navi-kun app, location information is continuously recorded using GPS even in the background.
Therefore, more power is required, so please be sure to bring a spare battery with you when you go out to sea so that your smartphone does not run out of battery in an emergency.
