I changed a couple things,,

"Perdon(Excuse me)Senior or seniorapuedo entrar a su propiedead a detectAr metales, por favor?"
And then you can add words/phrases like "pasa tiempo" (for "hobby of mine") or "enfronte" en frente (for "front yard"), or "en la tierra" ("in the dirt").
throw in a cerveza and that might grease some palms..be it Corona,Budlight...
Have you tried asking them in English? Some people automatically assume someone only speaks Spanish
and at the least do Spanglish...talking in Spanish with English words thrown in to describe something.
"vamos a la playa para buscar oro con mi metal detector"

"Let's go to the beach to look for gold with my metal detector"
Cause some words in Spanish get longer..detector de metal = metal detector, but literally translates to detector of metal..lots of phrases are
reversed in English.

Let's not forget how complicated English words can get with ..there,their ,they're, etc.
Good luck, and don't call anyone a "pendejo" trust me...

don't listen to your friends at the office saying that means "friend" in Spanish
