Diving Suit
The standard Diving Suit upgrade line raises its listed depth limit across six levels; the source separately reports a cold-resistant suit with an 800-meter limit.
How it works
ESTNN lists standard depth limits of 40, 80, 150, 230, 375, and 540 meters across six levels. It describes the suit as setting how deep Dave can go. The guide separately reports a cold-resistant suit with an 800-meter depth limit, without establishing how it is acquired or any further conditions.
