Quartz is one of the first and most important materials you'll need to find in Subnautica 2, since it's used to make some vital tools. This includes the Scanner, which is how you unlock basically every major blueprint, from the Sonic Resonator to the Wakemaker and Tadpole.
But finding quartz isn't easy when you're thrust into a monster-infested ocean with no idea what you're looking at. So here's where you should loot to get your first quartz, as well as how to stock up on the stuff en masse.
Subnautica 2 quartz location
Quartz is a white crystal which you can find in small chunks on and inside coral domes on the ocean floor, including under the Lifepod. These orange and green domes are easy to spot, and there are loads of them to the northwest of the Lifepod. Grabbing these quartz chunks by hand is enough to craft basic tools like the Scanner and to make glass to craft the Habitat Builder. There are also medium-sized crystals that you can smash with your Survival Multitool that'll give you a few more quartz at a time.
However, you'll soon need to find quartz wholesale, and that's when you're looking for large quartz crystals, which you'll need to mine using the Sonic Resonator. Large quartz deposits are most often found inside caves, but my favourite place to regularly visit is a large trench by a water current not far from the Old Habitat, roughly 350-400 meters north of the Lifepod. Here you'll find tons of quartz, titanium, copper, silver, and even lead, so it's been my go-to mining spot ever since.
