Dropped it in the water? We’ll get it back.
With our underwater drone we search up to 100 m deep for phones, keys, jewellery and stolen property. On lakes and in harbours all over Austria.
What we do & where
From finding a lost phone to inspections under water: on lakes and reservoirs, in harbours and at swimming spots all over Austria. Jobs abroad on request.
and everywhere in between
What we find for you
Dropped off a jetty, lost while swimming, or dumped in the water by thieves: we search where you can’t reach.
Lost something else?
Request a searchPhones & cameras
Smartphones, GoPros and cameras, often with photos that can still be saved.
Keys & glasses
Car keys, boat keys, sunglasses and prescription glasses.
Jewellery & wedding rings
We search for small valuables precisely, with partners using underwater metal detectors where needed.
Drones & gear
Crashed aerial drones, anchors, boat parts and sports equipment.
Stolen & dumped
Thieves often throw loot into the water: bikes, e-scooters, safes. We search for owners and insurers, in coordination with the police.
How it works
Send a request
Tell us what went into the water and where. Photos of the spot help us narrow the search.
We search
We bring the drone to the water and search the bottom systematically. The live 4K feed and 5000 lm lights show us what’s down there, even in murky water.
Recovery & handover
Found it? We bring it up and hand it over right at the shore, with a video of the find.
Recovered under the Reichsbrücke in Vienna
This is what things look like after a long time under water: bikes, e-scooters, safes, even a microwave, all pulled out of the Danube from about 5 metres deep during one recovery under the Reichsbrücke.
FIFISH V-EVO
A professional underwater drone that moves freely in every direction. It dives where it’s too deep for snorkelling and too much effort for divers.
Lost something? Here’s what helps
The first few minutes often matter most. The better you know the spot, the smaller the search area and the better the odds.
Stay calm, don’t stir
Don’t dig around on the bottom. Stirred-up mud kills visibility and can bury the item deeper.
Mark the spot
Tie an empty or half-full bottle to a string, weigh it down with a stone and drop it on the spot as a makeshift buoy.
Save the position
Take a photo with GPS location on your phone or save the spot in a maps app.
Note landmarks
Jetty, a distinctive tree, boat landing, swim ladder: ideally two points on shore that line up from the spot.
Note the conditions
Wind, waves, current and rough water depth. They help us work out where something sank or drifted.
Photos & description
Photograph the surroundings and describe the item: material, size, colour, anything special. Send it along with your request.
Prices on request
Every case is different: depth, visibility, travel. Tell us what happened and you’ll get a fair quote before we set off.
Private
Phone, keys, jewellery or camera: we often do private searches on a voluntary basis. We appreciate help with fuel and parking costs and an optional finder’s fee.
Business
For insurers, harbours, boat rentals, lidos and underwater inspections.
Good to know
- There is no guarantee of success. Water, visibility and the lake bed all play a part.
- Even if we find nothing, our own costs may apply, for example for trips over 100 km.
- We reserve the right to decline requests if a search seems hopeless.
Frequently asked questions
How deep can the underwater drone search?
Down to 100 m. The FIFISH V-EVO films in 4K and has 5000 lm of light, so we can see what lies on the bottom even in murky water.
Where does UDRA operate?
All over Austria: lakes, reservoirs, gravel pits, swimming lakes, harbours, marinas and the Danube, for example Wörthersee, Attersee, Traunsee, Wolfgangsee or Lake Neusiedl. Jobs abroad on request.
How much does an underwater search cost?
Prices are on request because every case is different: depth, visibility, travel. You get a fair quote before we set off. Private searches are often done on a voluntary basis; help with fuel and parking and an optional finder’s fee are appreciated.
My phone fell into a lake. What should I do?
Stay calm and don’t dig around on the bottom, as stirred-up mud ruins the visibility. Mark the spot, take a photo with GPS location and note two reference points on the shore. Then request a search as soon as possible, because currents and mud move items over time.
Do I need a diver?
No. The drone dives, nobody has to get into the water. It reaches places too deep for snorkelling and too much effort for divers, and streams a live 4K picture to a tablet.
What does UDRA offer harbours, lidos and insurers?
Inspection of hulls, propellers, anchors, chains, buoys, jetties and harbour facilities, reports and documentation with 4K video and photos, for example for insurers and damage claims, and checking the bottom before the bathing season, events or construction work.
Is success guaranteed?
No. Water, visibility and the lake bed all play a part. If a search seems hopeless, we say so and decline the request.

The sooner we search, the better: currents and silt move things over time.
