The Dave the Diver best weapons and upgrades depend on what the next dive needs to accomplish. A powerful rifle can make a boss safer, but it can also ruin the fish quality needed by Bancho Sushi. A net gun or tranquilizer produces better ingredients, yet may be the wrong choice when the story sends Dave against a dangerous target.

The most efficient approach is to build two tool paths: one dependable damage weapon and one live-capture option. Improve Dave’s permanent diving equipment alongside them, buying the upgrade that removes the current bottleneck instead of purchasing every available level in order.

These recommendations apply to the core game included in the full Android and iOS port described on the official Google Play listing. New players should also read our Dave the Diver mobile beginner guide before spending their first restaurant profits.

There is no single weapon that wins every category. Choose the loadout by objective before entering the water.

Best first weapon: Basic Underwater Rifle

The Basic Underwater Rifle is the safest first permanent weapon for most saves. Duff introduces it early, its blueprint is straightforward to obtain, and its balanced range and ammunition make missed shots less punishing than they are with more specialized weapons.

Use it while learning enemy movement, completing ordinary story dives and collecting materials for later branches. It is strong enough to solve early combat problems without forcing the player to commit immediately to a narrow playstyle.

Do not pour every rare material into the first elemental branch simply because it is available. The weapon system eventually offers damage, status and tranquilizing directions. Keep the basic rifle useful while deciding whether the save needs faster kills or better live captures.

The rifle is not the best ingredient tool. Shooting a fish repeatedly lowers its condition, so move toward nets and tranquilizers once Bancho Sushi begins paying enough to reward quality.

Best boss weapon: Red Sniper Rifle

The Red Sniper Rifle is one of the most practical boss weapons because range is a defensive advantage. Many large enemies are easiest to read from across the arena, where Dave has more time to avoid a charge, projectile or collision.

Its drawback is limited ammunition. A missed sniper shot matters, so search the arena for ammunition boxes and aim during predictable attack recovery windows rather than firing whenever the target appears.

Damage-focused sniper upgrades are useful when a specific boss is blocking progress. Elemental effectiveness can vary by encounter, which makes a universally ranked element less useful than matching the next target. If the necessary materials are scarce, a standard damage improvement may offer better value than building several incomplete branches.

The sniper is also convenient for dangerous sharks on material runs, but killing every valuable fish is not a good restaurant strategy. Carry a capture tool when the dive is about ingredients rather than a boss.

Best live-capture weapon: Net Gun

The Net Gun path is a major restaurant upgrade disguised as a weapon. It restrains compatible fish without damaging them, helping Dave recover higher-quality ingredients. Better condition can mean more usable meat and stronger menu value from the same encounter.

The Steel Net Gun is the long-term destination for players who regularly farm schools of suitable fish. It is especially useful when several targets can be controlled quickly instead of chased one at a time.

Size limits still matter. A net is not a universal answer for the largest sharks and other heavy creatures. Test it on the target type before planning an entire menu around a capture the tool cannot make.

For efficient farming:

  1. Identify which profitable recipe needs repeated fish.
  2. Confirm that the current net tier can restrain that fish.
  3. Reserve cargo capacity before the dive.
  4. Capture only enough stock for the next services.
  5. Spend rare upgrade materials after the route proves repeatable.

This ties weapon investment directly to restaurant income instead of collecting upgrades for completion alone.

Best option for large live fish: tranquilizers

Tranquilizing weapons create opportunities that nets cannot. A sleeping large fish can be recovered alive with the appropriate underwater drone system, preserving quality while avoiding a lethal finish.

The Modified Hush Dart is valuable for dedicated capture runs, while tranquilizer branches on familiar firearms can combine control with a weapon style Dave already uses comfortably. Some large targets require more than one successful tranquilizing hit before sleep takes effect, so leave room to evade while the status builds.

The Recovery Drone is part of the method. Putting a large creature to sleep does not automatically move it to the restaurant. If all drone uses have already been spent, another tranquilized target may provide no benefit.

Use damage weapons for bosses and forced combat. Use tranquilizers when the objective is a valuable live ingredient. Trying to make one loadout perform both jobs usually makes each job slower.

Which iDiver upgrade should come first?

iDiver improvements are permanent and benefit more dives than most individual weapon branches. The best order changes according to what currently ends the run.

Upgrade the Air Tank when oxygen is the limit

Oxygen acts as both time and health. More capacity gives Dave longer to explore and more room to survive mistakes. Upgrade it when dives repeatedly end with a rushed escape or when damage leaves no safe route home.

Extra oxygen does not justify aimless exploration. A planned route remains more profitable than staying underwater until the larger tank is nearly empty.

Upgrade the Cargo Box when weight is the limit

Cargo capacity often produces the clearest economic return. More space means additional fish, ore and crafting materials can reach the boat without slowing Dave as early.

Upgrade cargo when good dives are being cut short by weight, not when the inventory is filled with replaceable common items. Better collection choices can delay an expensive upgrade, while a genuinely undersized box will restrict almost every focused farming route.

Upgrade the Diving Suit when the story requires depth

The Diving Suit should follow progression. A deeper rating is essential when the next objective sits below the current safe limit, but upgrading it far ahead of the story does not improve ordinary shallow dives.

Buy the next suit level shortly before it is needed. This preserves money for air, cargo, weapons and recipe improvements that offer an immediate benefit.

Upgrade the Harpoon Gun when captures take too long

The Harpoon Gun remains useful for ordinary fishing throughout the game. Improve it when common targets repeatedly resist or when basic gathering consumes too much oxygen.

It will not replace specialized non-lethal tools for every high-quality catch. Think of the harpoon as the dependable daily tool and the net or tranquilizer as the deliberate quality tool.

A practical upgrade order by progression stage

Use this flexible route rather than treating it as a mandatory sequence:

  1. Opening dives: obtain the permanent Basic Underwater Rifle and improve air or cargo based on the first recurring problem.
  2. Early story: raise the Diving Suit only as objectives demand, then keep the Harpoon Gun comfortable for routine catches.
  3. Restaurant growth: start a Net Gun or tranquilizer path when ingredient condition affects profitable recipes.
  4. Dangerous encounters: build the Red Sniper Rifle or another familiar damage weapon for bosses and hostile deep-water routes.
  5. Repeatable farming: improve cargo and the Recovery Drone so high-quality captures actually reach the boat.
  6. Late specialization: finish the weapon branches used every week before spending rare materials on collection-only alternatives.

The correct next purchase should answer a visible problem. If Dave dies with spare cargo space, buy survival rather than capacity. If every dive returns safely but leaves valuable fish behind, buy cargo or capture capability rather than more damage.

Upgrade mistakes that waste resources

Avoid these common traps:

  • building several weapon branches at once and finishing none of them;
  • using lethal damage on fish needed for premium recipes;
  • upgrading the Diving Suit several stages before the story requires it;
  • buying more oxygen when poor route planning is the real problem;
  • tranquilizing large fish after using every Recovery Drone charge;
  • treating a boss weapon as the default tool for peaceful ingredient runs;
  • spending rare parts before confirming that the weapon suits the target.

Materials become easier to replace as new areas open, but early mistakes still delay equipment that would make every following dive smoother.

Best balanced loadout for most players

Maintain one reliable damage weapon, normally the rifle or sniper path that feels easiest to aim, and one developed capture path. Pair them with Air Tank and Cargo Box levels that prevent routine dives from ending prematurely.

Before entering the Blue Hole, ask one question: Am I fighting, progressing or farming? A boss dive favors range and damage. A story dive favors safety and flexibility. A restaurant farming dive favors live capture, cargo space and available drone uses.

That simple distinction identifies the Dave the Diver best weapons and upgrades more reliably than a fixed tier list. Once the haul reaches the surface, our best staff and restaurant setup guide explains how to turn it into faster service and stronger profit.
