By the time I started playing Pokémon Go, Pokévision no longer worked.
I recently read an article on BGR.com and found this website which accurately helps me track Pokémon - Fastpokemap.se. I got so excited I've made a video to show how this works.

Happy Pokémon hunting everyone. GONNA catch'em all!
Thanks for watching.
