If you’re looking to go underwater in Grand Theft Auto 5, there are a few things you’ll need. The first is a diving mask, which can be bought from any dive shop or from the police if you’re caught without one. The second is a snorkel, which can be bought from any store that sells diving gear. Finally, you’ll need some type of buoyancy compensating device (BCD), which will help keep you afloat when submerged.
