How the hunt works
Stand facing water, cast, and reel in whenever you get a bite. The Old Rod has the shortest species pool of all three rods, so it's only worth it for the handful of Pokémon it can hook.
The base rate in Pokémon Platinum is 1 in 8,192. There is no Shiny Charm in this game, so the base rate is the best you can get. Poke Radar chaining can reach ~1/200 in grass patches.
