6 total
| Name | Biomes | Description |
|---|---|---|
| Basic Fins | Simple diving fins that provide a small speed boost. The first Equipment unlock most players make. | |
| High Capacity Air Tank | Extends oxygen reserve substantially over the default tank. Required prep for the 101–250m Alien Ruins tier — the trip is too long for the default tank even with **Oxygen Control** equipped. | |
| Improved Fins | High-end fins with lightweight fiber construction and adaptive flexion. Fin fast, fin far. | |
| Rebreather | Helmet attachment that **eliminates the depth-scaling oxygen consumption penalty**. Without it, your air burns proportionally faster as you descend below 100m. Required prep for the Alien Ruins. | |
| Standard Air Tank | Holds breathing air. Standard All Environment Respiration design. | |
| Ultra High Capacity Air Tank | Ultra-high-capacity air supply. "For dives so long you'll forget you can actually drown." |
