# Instruments

The pressure is invisible until the hull starts cracking. These blocks tell you where you stand before it does.

* [Pressure Barometer](/create-deep-seas-wiki/deep-seas/instruments/pressure-barometer.md): the state of the hull at a glance, with a pufferfish.
* [Industrial Alarm](/create-deep-seas-wiki/deep-seas/instruments/industrial-alarm.md): a siren once the hull is past its limit.
* [Sonar](/create-deep-seas-wiki/deep-seas/instruments/sonar.md): maps the sea floor and shows contacts on the Onboard Computer.
* [Pressure Goggles](/create-deep-seas-wiki/deep-seas/instruments/pressure-goggles.md): a heat map of the pressure on every hull nearby.
