BHID multi tones on disc but all metal one tone--came back from Siesta Key and lots of clad no gold or silver--lots of pull tabs and caps--Got a tone on a pull tab dug 15 inches to get--only problem was i had to turn the sensitivity almost all the way down while in the water--never had to do that before--came home and works ok in my simming pool--anyone have any thoughts--also i was hitting everything in the wet sand-out of water
