The Silph Scope was seen in Celadon City. After Satoshi had been scared away from the Pokémon Tower by a Gastly, he saw several Team Rocket Grunts exciting the Tower, using a Silph Scope to avoid being scared by the ghosts.

Using the Scope, he was able to get past of the ghosts in the Tower and all the way to the top floor, where he encountered Mr. Fuji, who was being held captive by Team Rocket.
