Talk:Akashi's Improvement Arsenal/@comment-36.80.96.150-20151230184253

Okay, I'm a low leveled TTK, just got an Akashi from clearing 2-5 attempt. And I want to upgrade my Type 93 Sonars to a Type 4 one. My HQ level is 53 and I have both Shigure Kai Ni but do not have Isuzu Kai Ni. If I upgrade it with Yuubari instead, will it turn into Type 3 Sonars instead of Type 4 one?

Can someone tell me how since I don't want to waste my precious screws and I don't understand the table, nor how Akashi's arsenal works...
