GTA 5 Submarine Pieces
30 on this map
Submarine Pieces are wreckage recovered during Abigail Mathers’ Strangers and Freaks missions. This map marks 30 confirmed spots.
Like nuclear waste, you generally buy the Sonar Collections Dock before hunting them underwater. Each recovery pays out.
They usually are not a standalone Story Mode 100% collectible list item — treat them as mission/reward content.
Coastal and submerged wrecks are easy to revisit by mistake. Tick pins off as you clear them.
