The Harpoon application provides in real time the three essential informations for success in fishing.

- Where to find the right fishing structures.
- Which lures to use.
- How to present the lure to the fish.

The application provides you with this information at the time of the fishing depending on the fishing conditions, the species and the time of the fishing season.

Just select the fishing conditions you see around you and the application will do the rest. You will always have the right information to know where to fish in the water.

The app works as a virtual fishing guide that directs you to the best fishing practices depending on the weather conditions at any time of the fishing season.

The application does not require an internet connection and does not use your monthly data plan. It is the ideal solution, simple and fast, to know where, when, and how to fish.

A must for a successful fishing trip.
