Overview

Money can be difficult to earn during the early stages of How to Fish, so choosing the right upgrades is important. Some purchases help you catch better fish, while others provide the additional firepower, storage and speed needed to explore new islands and defeat stronger bosses.

These are the best items and upgrades to spend your money on throughout the game.

Helpful guides and tips for every stage of the game

Radar

The Radar is one of the first important items you should buy. It costs just $10 and allows you to follow the coordinates received after completing each island.

Purchase it after unlocking the boat so you can find the Forest Island and every location that follows.

Extra Inventory Slots

Additional inventory slots are one of the best long-term upgrades available. Every new slot allows you to carry another weapon, lure, piece of food or important quest item.

Buying multiple slots also allows you to keep different guns rather than leaving them on the ground. This becomes especially useful before boss battles, where you may want to carry a weapon alongside cooked fish and the required boss bait.

Better Fishing Equipment

Upgrade from your starting fishing rod when a better Fishing Rod becomes available. Improved fishing equipment makes the later islands more manageable and prevents you from relying on the basic equipment for the entire game.

You do not need to purchase every piece of equipment immediately. Upgrade when you reach a new island or begin struggling with its catches, while keeping enough money for weapons and bait.

New Lures

Each island introduces a new lure used to catch its local fish. These catches are generally more valuable and can be cooked before being sold, helping you afford the island’s other upgrades.

Boss Lures are separate from ordinary fishing lures and are usually much more expensive. Always check the full name before buying one, as purchasing the wrong version can waste a large amount of money.

Weapons

As you progress, you will unlock stronger weapons such as the SMG, Assault Rifle, and Sniper Rifle. The SMG fires quickly but can be difficult to control, while the Assault Rifle offers a more balanced option for dealing with enemies and bosses.

The Sniper Rifle is one of our favourite choices because its accuracy and high damage make earning a high Killscore much easier. Whichever weapon you choose, purchase attachments and upgrades whenever possible to improve its overall performance.

Bullet Damage Upgrades

Buying a stronger gun is only part of improving your damage. Shops also sell repeatable bullet upgrades that increase the damage dealt by your weapons.

These upgrades become increasingly expensive, but they are extremely valuable before later boss battles. Improving a weapon you already own can be more affordable than immediately replacing it with another gun.

Extended Magazine and Weapon Attachments

Weapon attachments can make your favorite gun much easier to use. The available options include:

  • Extended Magazine
  • Laser Sight
  • Red Dot Sight
  • Sniper Scope
  • Compensator
  • Suppressor

The Extended Magazine is especially useful because it allows you to fire for longer before reloading. A Compensator can help control the SMG’s recoil, while sights make it easier to track smaller or more distant targets.

A weapon can hold attachments across four slots. Completely filling all four slots on one gun also unlocks the Fully equipped achievement.

Boat Engine Upgrades

The first boat engine upgrade costs $230 and can be purchased on the Forest Island. It makes travelling between islands faster and unlocks the Getting an upgrade achievement.

Later, you can purchase the Dual Motors for $860 on the Rocks Island. This is the best boat engine and unlocks the I am speed achievement.

Boat upgrades are useful, but your weapon and essential quest items should normally come first. The standard boat can still reach every location, so speed upgrades can wait if money is limited.
