GTA 5 Scuba Diving: Nuclear Waste and Underwater Collectibles
GTA 5 scuba diving explained: how to dive with the Submersible and Dinghy, the 30 nuclear waste barrels worth 23,000 dollars each, wrecks, and sharks.

GTA 5 scuba diving is one of the most overlooked parts of story mode, and it opens up an entire ocean stuffed with collectibles, wrecks, and danger. The headline reward is the 30 nuclear waste barrels worth $23,000 each, but the seabed also hides sunken ships, hidden cash, and aggressive tiger sharks. Here is exactly how to dive, what to find, and how to reach the deepest spots without dying.
How to scuba dive in GTA 5
There is no separate "dive" button in GTA 5. You get scuba gear automatically by exiting certain watercraft while they are in the water. The three vehicles that equip the scuba suit are the Submersible, the Dinghy (the inflatable Zodiac-style boat), and the Kraken in the enhanced version of the game. Drive any of those onto open water, hold the exit control, and your character jumps out already wearing an oxygen tank and breathing apparatus.
Once you are in the scuba suit, the most important thing to know is that there is no breath meter. You can stay under indefinitely, which is what makes manual diving viable for collectible runs. Swimming controls underwater are the same as normal swimming, just without the timer. Repeated diving even nudges up your character's lung capacity stat over time.
The Dinghy is the best choice for covering distance, since it travels far faster on the surface than the slow Submersible. For pinpoint searching at depth, the Submersible is sturdier and lets you scan the seabed without leaving the cockpit.
The Submersible and the Sonar Collections Dock
The Submersible is the dedicated underwater vehicle, and the cleanest way to get a permanent one is to buy the Sonar Collections Dock for $250,000. The property sits at Paleto Cove on the north coast of Blaine County and unlocks for purchase after The Merryweather Heist. Buying it parks a Submersible at the end of the dock and a Dinghy on the right side, so you have both dive vehicles in one spot.
That dock is the key that unlocks the underwater treasure hunt. Without it, you can still find loose Dinghies around Los Santos and Blaine County to dive from, but the nuclear waste collectibles do not appear until the dock is yours.

Nuclear waste GTA 5: all 30 barrels and the payout
The biggest underwater payday is the nuclear waste collectibles. There are exactly 30 nuclear waste barrels scattered across the ocean floor around San Andreas, and each one you recover pays out $23,000. Collect all 30 and you bank a $250,000 completion bonus on top, for a grand total of $940,000.
A few things to confirm before you start the hunt:
- All three protagonists can collect the barrels, but the money always goes to whoever owns the Sonar Collections Dock. Many players park the dock under Trevor since he lives nearest in Sandy Shores, but the choice is yours.
- The barrels only become collectible after you buy the Sonar Collections Dock and finish The Merryweather Heist.
- You can scoop them up either by driving the Submersible into them or by swimming up to them in scuba gear.
- Recovering all 30 unlocks the Waste Management achievement and trophy.
To track them down, use the Trackify app on your in-game phone, which comes with the dock. Trackify only points you in the general direction of the nearest barrel, not the exact distance, so expect to sweep an area until the signal pings stronger. The barrels glow faintly, which helps you spot them once you are close on the seabed.
Underwater wrecks, hidden cash, and the sealed hatch
Beyond the barrels, the ocean is dotted with sunken wrecks: crashed planes and old ships half-buried in the sand. Many of these wrecks contain weapons strewn through the debris and briefcases stuffed with cash, so a slow pass through a shipwreck can be worth real money on its own. Wrecks also double as a safe haven, since swimming inside one will often make a stalking shark give up and swim off.
Two pieces of underwater content are famous Easter eggs you can find but not actually use. The Underwater Hatch off the east coast is a circular structure with a window that lights up as you approach, a clear nod to the TV show Lost. Off the north coast near Paleto Bay there is also a crashed UFO resting largely intact on the seabed. Neither can be opened or entered.
How to reach the deepest spots (and what kills you down there)
The ocean has a hard depth limit, and it punishes greed. If you swim too deep in scuba gear, the pressure starts draining your health until you die, so the deepest secrets like the hatch are effectively off limits on foot. Take the Submersible down past its own crush depth and the sub itself gets crushed. Treat anything that makes the screen darken and your health tick down as a wall, not a challenge.
The other lethal hazard is wildlife. Tiger sharks patrol deeper and farther-out water and spawn more often at night, showing up as a red blip on the minimap. A shark attack is an instant kill: a single bite ends you even at full health and armor, and it ignores the invincibility cheat entirely. Getting eaten unlocks the grim Out of Your Depth achievement. If a shark starts circling, sprint-swim to your boat or duck into a nearby wreck to break the chase.
For the best route through a collectible run: surface-travel on the Dinghy to a search zone, drop in to grab nearby barrels and wrecks by hand, then move on before sharks close in. Browse the GTA 5 screenshots gallery to see what the seabed and the Submersible actually look like in action.
