How it works

The Fisch infinite oxygen script continuously detects your oxygen level while you’re diving and forces it to stay at maximum, effectively giving you unlimited breathing time underwater. This lets you explore deeper areas without worrying about running out of air and surfacing prematurely.

It runs in the background during your fishing adventure, automatically refilling your oxygen bar whenever it decreases, so you can focus on catching fish and exploring. The script is designed to be lightweight and compatible with all current Fisch maps and updates.
