I need to power a buggy, with a metal detector attached to it. This metal detector uses 9 volts. It also contains 4 motors, all with 7.5 volts each. The weight of the whole thing is about 20kg. I was thinking about using a parallel circuit for the metal detector and another circuit for the metal detector. Thank you for your help.

For Christmas my boyfriend would like a metal detector, and I know nothing about them. He's never owned one before either so he also knows nothing about what to look for. My price range is around $100-$150, I know I can't afford the top of the line, but I'd like to get him something decent. What I need to know is, what's a good brand for a beginner? Also, what should I look for in a metal detector?

I was doing some metal detecting along the shores of Lake Ontario when I was on vacation. The mental detector went crazy beeping on this rock. I have searched several sources and even asked the guy at the metal detector store. Does anyone know what this rock might be? It is solid, dull black and you can see many flecks of black crystal like bits in it. I unfortuntely can't get a good picture of it?

I would like to purchase a metal detector. I want to use it on the beach and maybe at the edge of the water or in shallow water. I need something that is not to heavy and not too expensive. I want to look for stuff while I hang out at the beach with family.
