Booster Tank

+# Booster Tank+ +**Booster Tank** is a special oxygen tank available exclusively in *Subnautica: Below Zero*. It allows the player to trade oxygen reserves for a temporary increase in swimming speed.+ +## Overview+ +Equipped in the oxygen tank slot, the Booster Tank provides a speed boost when the **Shift** key is pressed. This increases swimming speed by approximately 0.5 m/s but consumes an additional 5 units of oxygen per second.+ +*   **Capacity**: Shares the same capacity as the High Capacity O₂ Tank (90 units). When equipped together, the total oxygen capacity is 135 units.+*   **Movement Penalty**: Equipping the Booster Tank incurs the same movement penalty as the High Capacity O₂ Tank (-0.47 m/s underwater and -0.61 m/s on the surface).+*   **Limitations**: +    *   The boost only draws from the tank's actual oxygen reserve, not Robin Ayou's lung capacity (the final 45 units).+    *   The boost cannot be activated close to the surface.+ +### Stats+ +| Attribute | Value |+| :--- | :--- |+| **Size** | 9 (3×3) |+| **Perks** | Higher air capacity and player boosting |+| **Debug ID** | `suitboostertank` |+ +## Usage+ +To use the Booster Tank, equip it in the paperdoll UI's oxygen tank slot. Press **Shift** while submerged to activate the thruster. The tank utilizes highly compressed air to ignite a small thruster, propelling the wearer forward. Environmental conditions such as atmospheric density and gravity rating impact kinetic energy transfer.+ +> Equipped with only a booster tank, Dr. Felicity Aman once escaped the underwater acid tentacle forest on planet Alpha671.+> ― PDA+ +## Crafting+ +The blueprint for the Booster Tank is obtained from a **Data Box**. It is crafted at the Fabricator.+ +### Blueprint Sources+ +1.  **Purple Vents**: Found in a narrow trench below the area where the Chelicerate patrols.+    *   Coordinates: `253 -137 -420`+2.  **Tree Spires**: Found at a tech site under a geothermally active fissure.+    *   Coordinates: `0 -451 -1118`+ +### Recipe+ +*   Requires Data Box from above locations.+*   Crafted at the Fabricator.+ +## Databank Entry+ +**Booster Tank**+The booster tank uses its large reserve of highly compressed air to ignite a small thruster, propelling the wearer forward. Environmental conditions impact kinetic energy transfer, especially atmospheric density and gravity rating.+ +**NB:** Requires I28f certification to operate.+ +Source: Unlock the Booster Tank+ +## Trivia+ +When first introduced, the Booster Tank more than doubled the player's swim speed and could be used without any limit while on the surface, making it the fastest method of traversing the world.
