The Cyclops Sonar Upgrade is an upgrade for the Cyclops, it functions similarly to the Seamoth Sonar, but can be toggled on and off. Every ping, a set amount of energy will be drained from the Cyclops (1% when using the default power cells), and it pings every ten seconds while active. This energy usage is not affected by the Cyclops Engine Efficiency Module.
Like all other Cyclops upgrades, it must be crafted at the Cyclops Upgrade Fabricator. The blueprint for the Cyclops Sonar Upgrade must be retrieved from a data box first, however. The data boxes containing the blueprint can be found in Wrecks.
