Skilled lookouts can be deployed on surface warships. Using their skilled naked eyes, they can largely contribute in scouting the enemy depending on the situation and before the advent of enemy radars, can spot for targets especially during night battles.
January 2015 Ranking reward. Was obtainable via the Hishimochi mini-event quest.
Increases cut-in chance of the ship it's equipped with during night battle; unlike Star Shells or Searchlights it does not affect other ships in your fleet. The visual effect of the equipment can be seen here. You see a sparkle at the corner of the ship's image right before the cut-in animation.
A piece of equipment to increase the reliability of night battle cut-ins for ships with an average or below-average Luck stat.
A crow's nest is a structure in the upper part of the main mast of a ship or a structure that is used as a lookout point. This position ensured the best view for lookouts to spot approaching hazards, other ships or land. It was the best device for this purpose until the invention of radar.
The IJN took great pains to maximize the capabilities of their lookouts, who were carefully selected for their superior night vision, supplied with enormous pedestal-mounted binoculars and trained to cover their eyes whenever their ships' guns were about to fire (as signaled by a double buzzer). Japanese ships always fired in salvo rather than continuous fire at night to ensure that lookouts could protect their night vision and the Japanese put considerable effort into developing flashless powder that both protected their lookouts' night vision and made the flashes harder for an enemy to detect and get a fix on.
