Pokéwalker

The Pokéwalker is a device that comes included with every copy of Pokémon HeartGold and Pokémon SoulSilver for the Nintendo DS. It is a pedometer designed to look like a Poké Ball. In the game, you can merge a Pokémon over to the pedometer wirelessly. Afterwards, each step you take will give one experience point to your Pokémon. Once you return, you can transmit the data back to the game. Transfers are all via infared which is built into the cartridge and the Pokéwalker. First, you transfer pokemon you want to walk with to the PC in the game. Then you restart and pick the Pokéwalker from the start menu. It can be tricky to sync, but after you go through the menu a few times you'll be able to do it. When the EXIT button comes up, you aim the Pokéwalker at the game cartridge about 2 inches apart and sync via holding the larger middle button for some time to get it to work (not just a quick push - you have to hold it) it will beep and make noises for feedback. As you wear it, it does sleep after some sitting and you have to press the bigger middle button a few seconds to wake it up. According to the operations manual, it doesn't record steps when blanked and is only made to store about one day of walking (10,000 steps). It should be synchronized every day. You do get pokemon and items while using it and can store three Pokémon and ten items. After ten items, it receives Watts instead of items. It says to use it for a half hour a day, with that guideline it should last about 4 months on a battery (CR2032 watch type). It starts with two courses: Refreshing Field and Noisy Forest. As you walk other routes become available: Rugged Road (50W), Beauitful Beach (200W), Suburban Area (500W), Dim Cave (1000W), Blue Lake (2000W), Town Outskirts (3000W), Hoenn Field (5000W), and so on for 32 total built in.

Usage
Each number on the counter is steps and every 20 steps is known as a Watt. For every 3-31 watts you can play the item finder (next to left most icon) and 10-31 watts to find and battle Pokemon (left most icon).

Poké Radar
The leftmost icon is the Poké Radar, which lets you find, battle, and possibly capture Pokemon every 10-31 watts. It shows four groups of tall grass and notes one with ! and you have to select it with the left and right buttons (to move to it) and Larger center button to select it. Select it several times (as it blanks and moves) and a Pokemon to battle/capture will appear. Then the buttons become (Ieft to right) Attack, Pokeball, Evade. You can capture 2 pokemon on your stroll.

Dowsing (Item Finder)
Item finder lets you find items every 3-31 watts. After picking a place will tell you if the item is near or far: near means it's next to the place you picked (left or right), far means at least one away (two or more places).
