If you feel like you have done every job and stunt jump in Grand Theft Auto V and the map is starting to feel a bit small, the ocean is where things get weird in a good way, especially if you have already experimented with different playstyles or even checked out GTA 5 Modded Accounts to mix things up. There is a side quest that only Michael can finish, built around hunting down thirty Submarine Parts scattered across the seabed. It is not just junk collecting; bit by bit you uncover what really happened to a woman named Abigail Mathers, and the whole thing turns the quiet blue water into its own little crime scene.

How To Start The Submarine Parts Quest

To even get this storyline going, you have to push the main plot far enough to finish the mission "The Merryweather Heist". A lot of players stop checking new icons after that point, so it is easy to miss what comes next. Once that heist is done, head up the coast to Paleto Cove and look for the Sonar Collections Dock. The place costs $250,000, which stings a bit if you are still juggling car upgrades and safehouse buys, but there is no way around it. Any of the three characters can technically buy the dock, but the trick is simple: buy it, then swap over to Michael, because he is the one who gets the "Death at Sea" Strangers and Freaks mission where Abigail shows up and sets the tone.

Gear, Sonar And The Actual Hunt

After Michael talks to Abigail, the game quietly hands you everything you need so you do not have to mess around with random boats or stolen scuba gear. A Dinghy with sonar is parked at the dock, and once you are on it you also get proper scuba equipment, so you can stay underwater without watching the breath bar and panicking. The loop is pretty simple but oddly relaxing: open the Trackify app on Michael's phone, watch the radar on the boat, and follow the ping to the next fragment. When the blip lines up, you jump in, drop down through the murky water, grab the Submarine Part, then climb back up and move on to the next signal.

Diving Tips And What Makes It Interesting

The thirty fragments are spread around the coast, and you quickly notice they are not all sitting in obvious spots waiting for you. Some lie in shallow water, basically right under the surface near wrecks or rocks, so you dip down, grab them, and you are back on the boat in seconds. Others sit deep, tucked inside broken hulls or half buried in the sand where the light fades out and the game's sound design suddenly stands out. On those dives you are just listening to the regulator, hearing muffled ocean noise, and trying not to swim straight past a glowing metal piece. It is slow, but in a way that suits the story; while you are picking up scraps you keep thinking about Abigail's version of events and whether any of it actually adds up.

Why It Is Worth Finishing

By the time you collect all 30 Submarine Parts, you have seen stretches of the map most players barely touch and you have a much clearer picture of Abigail's past, plus a payoff that fits Michael's darker sense of humour. It is the kind of side content that makes the world feel bigger without throwing another shootout at you, and it works even better if you like messing with different builds, money routes, or, for some players, buying gear and extras from places like buy game currency or items in RSVSR while still chasing in-game mysteries through GTA 5 Modded Accounts.
