Can I get there?

Pick a vehicle and depth module to see what's within its crush depth, or dive on foot to see how long your air lasts. All numbers come from the game's vehicle and breathing code.

Biomes

Depth range of each biome's seabed (most of its spawn spots); the white line is your crush depth.

Resources

A resource counts as in reach when its shallowest common spawn depth is.

Air on foot

Seconds of air from full, holding one depth. The game drains oxygen faster below 100 m and again below 200 m. A Rebreather keeps the drain at the surface rate at any depth.

The Seaglide has no crush depth; your air is the limit. You take no pressure damage when swimming.

Depth modules don't stack: the vehicle uses the best one fitted.

Habitats

Bases have no crush depth. They have hull integrity: it starts at 10, and each room, corridor, window and hatch below the surface adds or removes points; the penalties grow below 100 m (×2 by 1100 m). Below zero the base floods one section at a time.
