Okay, I understand. You're looking for a metal detector that's sensitive enough to reliably detect 2€ coins in a park environment. I'll focus the search on detectors known for good sensitivity to small, high-conductivity targets, and also consider models suitable for general park use (durable, easy to use).

Okay, I've reviewed the search results. Here are a couple of options that look promising for finding 2€ coins in a park:

1. Nokta FINDX PRO Professional Metal Detector:

2. Bounty Hunter Quick Draw Pro Metalldetektor:

The Nokta Simplex Ultra looks good too.

Do any of these seem like a good fit, or would you like me to refine the search with any specific features in mind (e.g., a specific price range, or discrimination features to filter out certain types of metal)?
