Query: Useless for me

I bought this tool to detect screws in drywall and it just doesn't. It detects only the metal corner reinforcement. [Money] wasted. PLUS it requires a battery, which isn't included for some reason (after 30 years of customer disappointment you'd think batteries would always be included now). Even when you put it in the cart, the cart doesn't offer you batteries... worthless, irritating.
