Dave the Diver: Beginner Tips for Diving and Restaurant Management

The Two-Phase Day

Each day has two dives (morning and afternoon) and one restaurant service (evening). Missing the restaurant service forfeits that night's income — always dive in time to collect ingredients and staff for service.

Oxygen Is Your Main Resource

Oxygen depletes constantly while diving. Upgrade your oxygen tank early from Cobra. Every meter deeper costs more oxygen, so efficient routing matters. Don't free-dive past 130m without upgraded tanks — you won't make it back up.

Harpoon vs. Nets vs. Tranquilliser

Harpoon guns deal damage and kill fish (giving lesser ingredients). Nets and tranquilliser darts capture fish alive, yielding higher-quality ingredients and enabling the Fish Farm later in the game. For boss fish, you'll need your best harpoon, but for daily collection, tranquilliser builds are more profitable.

Staff and Restaurant Upgrades

Hire staff as soon as possible — you cannot serve enough tables solo. Staff level up over time and unlock chain service bonuses. Tip generously in the restaurant mini-game to keep VIP customers satisfied. VIP nights dramatically increase income.

Blue Hole Depth Zones

The Blue Hole is divided into three depth bands: Shallows (0–130m), Mid (130–250m), and Deep (250m+). Each zone reshuffles at dawn and dusk — the same fish won't always be in the same place. Certain story fish only appear at specific times of day.

Don't Neglect Bancho's Sushi Minigames

Bancho's sushi preparation mini-games increase the quality rating of dishes, which directly multiplies their sale price. A 5-star dish sells for 3× more than a 1-star version of the same recipe. Practise the timing.
