How does the Itemfinder work in Pokemon Crystal?

The Gen II Itemfinder only confirms that a hidden item is somewhere on the visible screen. It does not point to the tile, so walk to the landmark, face the likely tile or object, and press A.

Quick Answer

Use the table as your route sweep

The Itemfinder does not give a direction in Pokemon Crystal. If it reacts, the hidden item is somewhere on the visible screen. Use the area, coordinate, and access filters below, then face the suspected tile or object and press A.

Story Blocker

Machine Part

Search Cerulean Gym during the Kanto Power Plant story. This hidden item is required to restore power and continue the Kanto route cleanly.

Rare Pickup

Berserk Gene

Surf in Cerulean City near the old cave area. It is easy to miss because the item is hidden on water rather than a normal floor tile.

Power Items

Rare Candy and PP Up

Use the priority filter for permanent-value items such as Rare Candy, PP Up, Max Revive, Full Restore, vitamins, and Moon Stone.

Itemfinder Tips

When the Itemfinder says something is nearby

Check the whole screen

The reaction means the hidden item is on the visible screen, not next to your character. Move around the landmark and press A from different sides.

Water can hide items

Cerulean City's Berserk Gene and Cerulean Gym's Machine Part are reminders to search water tiles once Surf is available.

Old saves need a reset sweep

If you cannot remember what you collected, filter to priority items first, then run the area list in story order and mark confirmed empty spots.
