Most studs have things (like drywall) nailed to them, and the nails are usually made of iron. So, all you need is a high-power rare earth magnet. I use a particularly strong refrigerator magnet.

If you want to splurge (or are willing to couple trips to the coffee shop), you could buy one (or two) of these:

I was tipped off to these by the someone in the construction industry. He buys a few whenever they're in stock, so that he can have them in every toolbox, lose them, etc.

Note that, once you find a nail head, you can just leave the magnet hanging in place. If you have two, you can hang both, then use a straightedge or chalk-line to mark the point between the two where you want to make a hole. The fancy radar puck thing can't do that. (Maybe, someday, fancy AR goggles will solve that problem, but we're a long way off from that.)

This doesn't work for conduit and plumbing. mmWave radar does.
