Net A Fish Spear Gun Guide: Upgrades and Turret Mode

The Spear Gun fires automatically at fish passing your dock. It focuses on fewer but larger fish and excludes Common fish. Its starting configuration catches Uncommon through Rare, with one fish every 80 seconds at Shore range.

Find Your Spear Gun at the edge of your dock. Its status cycles from a next-volley countdown to firing, then starts the next countdown. Every speared fish is reeled in and sent to the Fish Cooler, without a separate manual reel-in action.

The device keeps its own countdown while you use your net or other helpers, and its catches can discover new species for your collection. Open the Cooler to manage those catches; use the Cooler guide for equipping your best fish, selling extras and setting Auto-Sell. For a setup that runs several fishing systems together, see helpers and online AFK fishing.

1. Approach the Spear Gun and press E when Upgrade appears.
2. Read the current stats and each upgrade’s next effect, cash price and Rebirth requirement.
3. Buy the upgrade that fits your goal, then check the updated stats and next offer.
4. Scroll below Range to find Barbed Tips.

Which upgrade should you buy first?

• For rarer fish, prioritize Sharper Tips. It raises the maximum rarity the device can catch. Follow the rarity preview: some purchases leave the displayed ceiling unchanged, so one purchase does not always open a new rarity. Early on, reaching Epic requires progressing through the Rare-ceiling levels.
• For more catches, compare Multi-Spear with Fast Reload. More fish per volley and shorter waits both improve throughput. At the starting configuration, the first Multi-Spear purchase doubles the volley from one fish to two for $1,300. That makes it a strong early quantity upgrade compared with spending $1,000 to shorten the interval from 80 to 72 seconds. Recompare the offers as prices and effects change.
• For larger fish, choose Range. It reaches farther into areas with bigger fish and adds a fish-size bonus. The first level adds 3 studs and 8% size; level 15 reaches +45 studs and +120% size. Choose it when size is your goal rather than treating it as a catch-count upgrade.

Once your rarity ceiling reaches the fish you want, improving quantity and reload speed gives you more catches within that range. Use the catch-rate calculation to compare those two purchases.

Why an upgrade is locked

Sharper Tips and Multi-Spear both require Rebirth 7 to advance beyond level 10. At that point, Sharper Tips allows catches up to Demigod, while Multi-Spear catches 11 fish per volley. Reach the required Rebirth before buying the next level; see Rebirth requirements and unlocks to plan that milestone.

A Rebirth lock is separate from the overall level cap. Sharper Tips, Multi-Spear and Fast Reload each have 34 levels, Range has 15, and Barbed Tips has 10. Read the requirement on the specific upgrade you want to buy.

Calculate fish per minute

Use the Catch and Speed values from the same configuration:

Fish per minute = fish per volley × 60 ÷ seconds per volley

These are configuration examples. Moving from five fish every 40 seconds to eight every 32 seconds doubles catch throughput from 7.5 to 15 fish per minute. It does not imply twice the income: rarity and fish size are separate parts of the comparison.

The menu rounds the starting rate to approximately 0.8 fish per minute. Later, a Fast Reload preview can display 9 seconds → 9 seconds because the interval is shown in whole seconds. That display does not establish identical underlying timings; use the menu’s fish-per-minute readout to compare those configurations.

Speed up the Spear Gun with skills

Open Rebirth → Skill Tree → Crew & Dock. Learn Fisherman Drills to open Spear Training, then spend one Skill Point per rank on Spear Training. Its first rank makes the Spear Gun 2% faster, the next rank raises the bonus to 4%, and the fifth and final rank reaches 10% faster operation. See the Skill Tree guide for broader point-allocation choices.

Two helper passes also affect the Spear Gun:

• Turbo Helpers: the Spear Gun, Fisherman and Boat work 50% faster and bring back twice the fish.
• Helpers Luck: doubles luck for those same three helpers, helping them find their rarest fish more often.

Choose speed and extra fish for catch volume, or helper luck for more frequent rare catches within the device’s available rarity range. Raising that range is Sharper Tips’ role.

Enter and leave Turret Mode

During normal fishing, the nearby E interaction opens Upgrade. During an active Megalodon encounter, the Spear Gun provides a manual boss interface:

1. Go to the Spear Gun when the encounter prompts you to use Turret Mode.
2. Press E at Fight the Megalodon / Turret Mode, or select the encounter’s ENTER TURRET MODE shortcut. The shortcut also displays Q as an entry control.
3. Once inside, press Q or click the red X to leave and return to the dock view.

For aiming, shooting, range handling and collecting victory rewards, follow the Megalodon boss guide.
