Poké Walker

The Poké Walker is a device that came out with Pokémon HeartGold and SoulSilver that allows you to take any Pokémon you have captured in the game with you in real life, so long as you have a Pokémon in the PC Boxes.

Usage
To access the Pokéwalker, you must have at least one Pokémon in a PC Box and select CONNECT TO POKéWALKE from the main menu. From there, the game will instruct you to select a Pokémon from the PC Boxes and select a path, and, once the transfer is completed, you are able to walk around with the Pokémon inside of the device.

Effects
Everytime the device records that 20 steps have been taken the player recieves a Watt (W), a type of currency that is used to play the minigames included in the PokéWalker and to unlock new routes. In addition, every other trip into the PokéWalker grants the Pokémon the same effect as a Rare Candy, gaining a level.

PokéRadar
To use the Poké Radar, you need 10 Watts for every use. It shows 4 patches of grass and one with a "!" on it, which may increase in amounts if it keeps going up to "!!!". Use the arrow buttons and the center buton to select the grass with a "!". Once you select it, a battle will commence or another clump of grass may show the "!!!". In the battle, both Pokémon will have only 4 HP each, and you will have three options: Attack, Evade, and Catch which are as followed:
 * Attack means that your Pokémon does 1 HP damage to the enemy, but either Pokémon can do a critical hit, resulting in a 2 HP damage.
 * Evade is to evade your enemy's attack and attack back, but be careful because the enemy might run when you use it.
 * Catch is throwing a Pokéball at the Pokémon and either capturing it or it runs away.

Dowsing Machines
To use the Dowsing Machine, you need 3 Watts every use. When you start, the device show you a series of six grass patches of which you select one of them. If you select a patch that contains an item, the minigame ends, but, if you are incorrect, it will give a clue as to how close you are to the item. If the item in the very next patch, in either direction, it will tell you that "it's near". On the other hand, if the item is two, or more, patches away from the one you selected, the device will tell "it's far away". If you do not select the correct path the second time, the minigame ends by showing you where it was.

Routes
In every route when you choose to use the pokeradar you have a chance to fight one of six Pokémon or find some items.
