Hydroacoustic Search Data
Available on all cruisers Tier IV and above as well as German battleships (from tier VIII), German destroyers (from tier VI), and British destroyers (from tier VI), this consumable increases detection capability of enemy torpedoes and ships. It will detect any ship within the detection range regardless of any obstacles such as smoke screens or islands. It will also detect torpedoes at roughly double to triple a typical torpedo's detection range. The torpedo detection bonus stacks with the Vigilance commander skill. This consumable can be very useful for hunting destroyers and detecting torpedoes early enough to properly evade them.
The detection ranges are usually very consistent among ships of the same tier, with the exception of German ships: they have a superior version of this consumable with greater range and/or duration compared to their competition.
As the player progresses to higher tiers, the detection ranges of this consumable typically increase accordingly. The exception here is British destroyers, which have uniform duration and ranges across all tiers.
This consumable can be exchanged for Defensive AA Fire () on most cruisers. American light cruisers and Italian cruisers can mount both simultaneously; British cruisers can only mount Hydroacoustic Search.
*: As of 0.8.0, premium cruisers Yūbari, Kronshtadt, and Stalingrad are the only cruisers above tier III that cannot mount this consumable.
**: As of 0.8.0, Gallant is the only British destroyer that cannot mount this consumable.
***: Ernst Gaede only gets access to Hydroacoustic Search upon mounting B hull.
