|This item only works with enemies that you kill, it doesn't passivly collect flotsam off the water.|
The cargo transporter automatically collects wreckage of downed enemies. After the cargo transporter has beamed wreckage to your cargo bay, it will need some time to regenerate. This means that no sea wreckage can be collected during this time. Once the cool-down time is complete, the transporter will automatically move onto the next wreckage collection. You can activate and deactivate the cargo transporter as soon as you‘ve equipped your sub with it at the dry dock.
