Zoom Lens

Boosts accuracy by 20% when moving after the opponent. (Hold)

Zoom Lens gives a 20% accuracy bump IF you move after your opponent. This works well with slower Pokémon or Trick Room teams!

This is better than Wide Lens's flat 10% boost if you're consistently moving second. Slow Pokémon with inaccurate moves like Focus Blast or Stone Edge can benefit from the larger accuracy boost. Just remember it does nothing if you move first.
