We use an app to guide our treasure hunt! A success?

We throw our magnets in the place where it all started for us! It's hard to find any promising spots here, so we decide to use an app to guide our treasure hunt.
This collaborative app allows you to report the presence of fly-tipping.

So we try to go there to check if there are also abandoned objects at the bottom of the water!
We also make some great discoveries like a World War II ammunition, a nice knife, and unfortunately also a scooter...
