The Pneumatic Helmet/$ is one of the four Pneumatic Armor/$ pieces.

For a long time, it was the only piece available.

Crafting a Pneumatic Helmet

With an Entity Tracker/$ upgrade installed, living creatures within a range of 16 blocks will be automatically tracked, even through walls. When the entity is an aggressive mob you'll get a warning if it targets you. This allows you to prepare for battle (or escape!). You can filter in the GUI the entities which should be tracked with an Entity Filter/$.
