Component	Problem	Solution / Løsning
Aeration devices that makes airbubbles inside the cage. Sold under names like(Midt-Norsk ring, Turbolift etc)	The echosounder picks up the bubbles and it creates a noisy image of the fish.	Echosounders are not compatible with aeration ringsdevices.

Aside from these components, the equipment is compatible with any other component that is not directly interfering with it. It is compatible with predator nets.

1.2 Cage requirements

Minimum 15m deep nets.

Info

What happens if the requirement is not met:

Performance suffers because to the the sonar coverage in the cage is very low.

Deeper cages enable deeper sensors and therefore more coverage.

1.2.1 Coverage for different cage sizes:
