I'm currently renting an apartment and my spouse and I want to hang a metal fixture above the wall where our bed is (in lieu of a headboard...for now at least). Where I want to hang it is 4 feet above the only electrical socket on that wall and I drew a line 5 feet width.

The stud detector is detecting live wires all throughout the line I drew, which seems a bit crazy to me. The socket does however control the light switch on the adjacent wall and the light fixture on the ceiling so maybe there is just a huge square of electrical wiring on the wall.

Should I be trusting the detector? I get mixed results depending on where I start the detector and if I start it in a certain position once it picks up the live wire it seems to keep the light on for feet, until I'm about a foot away from the line I drew, which would be about 4 feet from where the hole I marked is. Since the piece is metal it's a bit heavy (like 10 lbs at most) so I was going to use some heavy duty metal drywall anchors (just in case) that are also quite sharp, so I'm very leary on this.

Thanks for any responses.

I think you should reconsider hanging a heavy metal fixture above your bed using just drywall fasteners. If it should accidentally come down while you were in the bed you may just not ever wake up again. – Michael Karas Sep 1 '13 at 20:34
I hear ya. It's maybe 10 lbs max. Not too heavy, but heavy enough for me not to trust those plastic anchors. – EHorodyski Sep 1 '13 at 20:41
You may want to look at this discussion about anchors. – bib Sep 1 '13 at 21:41
You also may be detecting horizontal bracing or metal studs. – bib Sep 1 '13 at 21:44
If you should damage a wire it will be very difficult to properly repair. If you're going to make holes to find structure, you're better off lightly tapping a small nail through the drywall. Almost impossible to damage wiring this way. The building may have foil backed wallboard or insulation which confuses most electronic stud locaters, rather than containing that much wiring. – bcworkz Sep 2 '13 at 18:06
