I founded it!!!
"King of California" http://www.imdb.com/title/tt0388182/
Michael Douglas in one scene hold Minelab Excalibur, showing to his daughter and says " ...meet the Excalibur!.."
Next scene; he presents and explains to her, basic Excalibur behavior..and next thing - he detected and dug old spanish gold coin - dublon! Wow!

I analyzed that scene few times...hmmmm...it was Excalibur on scene...but sound was more like from GP 3500!!! Ha,ha,ha! Do watch that part and tell me what do you think!?

Just read this short comment:
"..An unstable dad who after getting out of a mental institution tries to convince his daughter that there's Spanish gold buried somewhere under suburbia..."
Ha,ha,ha!!! I am affraid most of us will face same destiny...sooner or later! ("mental institution" part!!) Boooahahahahahaha!
