Cargo Box
Cargo Box upgrades raise listed capacity from 9 kg at level 1 to 185 kg at level 10, increasing how much dive cargo can be carried.
How it works
ESTNN lists ten capacities: 9, 13, 19, 30, 42, 63, 94, 125, 155, and 185 kg. Level 1 is listed as free, with later levels carrying Gold costs. The guide describes the box as helping bring back collected dive finds. It does not explain which objects count toward capacity or how weight is calculated.
