The Poké Radar is the most powerful tool of the fourth generation for collectors. It flushes out Pokémon you can’t find any other way and, used well, it makes Shiny Pokémon appear with unprecedented regularity. It all comes down to one skill: knowing how to chain.
Professor Rowan gives it to you along with the National Pokédex. You use it from the Bag, in tall grass, and it recharges after you walk 50 steps. The Poké Radar chain counter on the Pokétch, given by Professor Oak at Pal Park, displays your current chain.
This guide details the technique step by step, along with the mistakes that can cost you a chain of thirty encounters.
