We have tried all manner of gadgets over the years and haven’t found anything more accurate than a hammer and a tuned (experienced) ear. Gentle taps (so as to not damage roof) are all that’s needed. We also have a 12” piece of solid #10 copper in each tool belt for those tricky roofs where rafter spacing isn’t consistent or there are sistered rafters for long spans. Insert the wire thru a test hole, bend into a U shape, then rotate to find exact location of rafter, mark with chalk, then go to town.
