PokéNav
A PokéNav is a type of electronics equipment found in Hoenn. It's short for "Pokémon Navigator". It was produced by the Devon Corporation under the orders of Mr. Stone, who wanted to find a way to keep track of a Pokémon's feelings. Mr. Stone gives it to the protagonist of Pokémon Ruby, Sapphire, and Pokémon Emerald for recovering the Devon Goods from Team Aqua or Team Magma. They appear to be small, compact-disk-shaped devices.
In the Pokémon anime, Max has a PokéNav he received as a traveling gift from his parents.
They are chiefly useful for Pokémon Coordinators to keep track of a Pokémon's status for Pokémon Contests.
It has several functions:
Map
The PokéNav displays a map of Hoenn, along with the current location of its owner.
Condition
The PokéNav checks the Cool, Beauty, Tough, Smart, and Cute condition of Pokémon in detail. It can search through party Pokémon only, or all Pokémon owned combined.
Trainer's Eyes
The PokéNav will keep track of 69 unique trainers and alert the user when they want a rematch. Appears only in Pokémon Ruby and Pokémon Sapphire.
Entry Call
