Mastering Dave the Diver requires balancing two distinct gameplay loops: diving for marine life in the ever-shifting Blue Hole during the day and managing Bancho Sushi by night. To maximize your early-game efficiency, you need to prioritize upgrading your Oxygen and Carry Weight capacity immediately, invest in the Old Underwater Rifle or Basic Underwater Rifle enhancements, automate your restaurant staffing via Cooksta, and carefully manage your weight threshold to avoid losing precious catches. Whether you are coming from deep strategy titles like Mount and Blade 2 or fast-paced action adventures like Monster Hunter Wilds, surviving Dave's aquatic ecosystem demands precision and resource discipline.
Prioritize Oxygen and Weight Capacity Upgrades First
Your primary bottleneck during early dives is your limited survivability and inventory space. Every single dive consumes oxygen as you swim, harvest items, and take damage from hostile marine life like Blacktip Reef Sharks and Humphead Parrotfish. When you visit the surface between dives, immediately open your smartphone and access the iDiver app. Pour your initial gold earnings directly into upgrading your Suit (which increases your max oxygen capacity from 100 up to 350+) and your Meow Diner Carry Weight (which expands your inventory limit from 15kg up to 50kg+).
If you ignore these upgrades, you will find yourself constantly swimming back to surface pods or forced to abandon high-value items like White-spotted Jellyfish or Bluefin Tuna. Think of your early gold investment as building your foundational infrastructure, much like optimizing loadouts in Phasmophobia or gathering critical upgrade components in Roblox crafting titles. Upgrading your diving gear also allows you to explore deeper thermoclines without panicking about running out of air halfway through a salvage run.
Unlock and Upgrade the Right Early Weapons
Relying solely on your basic harpoon gun will severely limit your ability to take down aggressive predators and harvest high-tier sushi ingredients. Early in chapter one, you will unlock Duff's weapon shop via the smartphone, which introduces the weapon crafting and upgrade tree. Your top priority should be tracking down weapon materials inside yellow weapon chests scattered across the Blue Hole to unlock the Basic Underwater Rifle and subsequently upgrade it into the Red-tipped Rifle or a tranquilizer variant.
Tranquilizer weapons are exceptionally powerful because putting a fish to sleep allows you to capture it alive via drone rescue, yielding maximum meat quality and higher profits at Bancho Sushi. For players who love intense combat loops similar to Remnant 2, mastering gun upgrades is essential for handling tougher minibosses. Avoid sinking resources into melee weapons early on; the knife is serviceable for clearing seaweed and defending against small pests, but ranged options keep Dave out of harm's way.
Master the Morning and Afternoon Dive Routine
Time management is the hidden currency of Dave the Diver. Each in-game day is split into a morning dive, an afternoon dive, and an evening restaurant service. You cannot afford to waste your dives wandering aimlessly. Before jumping into the water, check your Cooksta menu requirements and your active missions via the EcoWatcher app or text messages from Otto and Duff. Plan your dive around specific ingredients you need for upcoming VIP visits, such as Bancho's special curry or shark party events.
Furthermore, pay close attention to the shifting layout of the Blue Hole. The seafloor map randomizes terrain features, item spawns, and weapon chests on every single run. Make sure you clear out shallow areas efficiently before descending past the 50-meter mark where oxygen drain accelerates.

Optimize Bancho Sushi Staffing and Menu Automation
Once the sun sets, Dave shifts from explorer to waiter at Bancho Sushi. Running the restaurant effectively requires strict control over your menu pricing, dish quantities, and staff hiring. Never put too many different dishes on the menu; instead, focus on preparing 2 to 3 high-value dishes in large quantities. As you progress, you will unlock staff management through the Cooksta rating system. Hire competent employees like El Nino for the dining room to handle customer service and cleaning, and Mastch or James for the kitchen to speed up preparation times.
Training your staff using coins and ingredients significantly boosts their stats in cooking, serving, and appeal, which directly increases your restaurant's daily earnings. Neglecting your staff results in disgruntled customers, wasted food, and low review scores on the Cooksta app. Keep your operations lean, automated, and hyper-focused on customer satisfaction.
Utilize Smartphone Apps and Farming Systems Effectively
Your smartphone is your command center in Dave the Diver. Beyond weapon crafting and restaurant management, you must actively check apps like Cooksta, FishMon, and the Marine Farm. Once you unlock the fish farm in Chapter 2, stop selling every single fish you catch. Instead, keep a mating pair of high-value fish—such as the Titan Triggerfish or sharks—in the farm to passively breed endless supplies of rare ingredients without risking your oxygen in dangerous waters.
Additionally, keep track of periodic events and side quests issued by eccentric characters like Udo the photographer or Duff. Completing these tasks unlocks crucial quality-of-life gear, including the salvage drone and diving suit modifications.

By combining smart marine farming, optimized weapon loadouts, and efficient restaurant management, you will conquer the depths of the Blue Hole with ease.
