Stay where you are and fix the spot. A lake has no tide, and a ring that comes off on the shore is almost always still there.
Then tell the lido staff and the town's Polizia Locale. If you are leaving soon, post a request before you go.
Real sand is rare at Garda. Most beaches are gravel or pebbles, many lidos are lawns running down to the water, and around Sirmione the shore is flat slabs of rock.
On pebbles a ring drops into the gaps and stays there. You will hardly ever see it, but a metal detector reads straight through the stones. Digging it out is slower than in sand. It has usually not travelled.
On grass a detector is quick work. On the Sirmione slabs a ring tends to end up in a crack, and a mask and snorkel in the shallows can beat any machine.
In the north the lake sits in a narrow valley between mountains, and the bottom falls away steeply close to shore. Something dropped off a jetty or a boat there is soon out of wading depth. That is a job for a diver, not a detectorist.
The south, around Desenzano, Sirmione and Peschiera, is wider and in many places shallower. A ring lost while swimming there often stays at standing depth.
Say in your request how deep the water was, even as a guess: waist, chest, or out of your depth. That one line tells a searcher whether to bring a detector or find a diver. Diving on Garda has its own rules, which differ from shore to shore, and the diver deals with those.
Garda is split between three regions, Trentino in the north, Lombardy on the west shore and Veneto on the east. There is no single lost-property office. Each town runs its own.
Tell the lido and the beach bar as well. Private lidos and hotels often keep what they find rather than pass it to the town, so ask in both places.
The remains of Bronze Age lake villages lie around Garda, some of them underwater close to the shore, off Manerba, Sirmione and Peschiera. They are part of the UNESCO World Heritage site of prehistoric pile dwellings around the Alps. A detector has no business there, and under Italian law anything old lying on a lake bed belongs to the state (Codice dei beni culturali, art. 91).
Italy has no national rule against using a detector to recover your own ring. What the law reserves for the state is the search for archaeological finds.
The Veneto region's 2026 bathing-season safety ordinance for the east shore says nothing about detectors. A town can still ban them on its beaches for the season, and many lidos are run under concession. So the searcher checks the town's current ordinance and asks the lido. None of that is your job as the owner.
Plenty of people only notice on the motorway or while unpacking. You do not need to go back. The town, the beach or lido, and the day are enough to start.
Still at the lake with a flight soon? What to do before you fly home.
Retrievly does not search. It puts you in touch with people who own a detector and will go out and look.
We are new at Lake Garda, so there may be nobody signed up near your beach yet. Then we go and find someone: you post the request, we ask in the detecting groups and forums around the lake and send them the link.
Only a rough circle is shown in public. The exact spot goes to the one person you pick.
No money goes through Retrievly. A thank-you, if you want to give one, is between you and whoever goes out.
Post soon and draw the circle tight: those two decide it more than anything else. Retrievly vets nobody, so meet in daylight, somewhere public.

Kenny built Retrievly. He has snorkelled the Danube for years and keeps bringing up things that belong to other people: wallets with the ID still in them, phones, keys. That is where Retrievly came from.
