Never occurred to me to use magnets to find rafters.... got a link to how? I know it seems simple but also seems like it would take strong magnets?
The little magnets from Harbor Freight weren't strong enough, so I got some from eBay.
With brackets attached to the clamps by screw, I stuck one magnet on each, both facing same way.
My rafters are expose in the attic. Pair of this clamps let me find both ends from outside.
Magnet only had to work through 1" of wood and roofing.
The cheap compass I got seems sticky, could be better ones. It did point toward magnets from several inches away.
