Indeed.

I am sad to say that I have the same sculpture on a shelf around here somewhere. The trouble is that all the nails used to tack down the shingles interfere. The same happens with a flat roof with the first layer of tar paper tacked down. On one flat roof job I was able to get good confidence on the rafter location by doing many many passes in order to develop a kind of night sky of markings where the rafter showed up as the milky way. Haven't used the D-Tect since.

We have tried a number of products.  The D-Tect is in amazing stud finder
but did very little on shingle roofs.  The mechanism by which you run it
across a surface is clearly not made for shingles.  It is basically a
$1000 sculpture on the top shelf in our shop.

I am still not aware of any great method for identifying rafters.

Hello, Mechanix~


"Sub Scanner" was mentioned a couple of seasons back so I wonder if
those who "bought in" could "weigh in" with their opinions? My main
goal is to scan through composition shingles and find the trusses for
anchor points...with no goofs. Also I'd like to find wall studs when
scanning through synthetic stucco & exterior rigid foam insulation.

Bosch D-Tect 150 is a more costly version in this glorified "stud
finder" category; that one seems to have a bigger display and no need
for calibration. Could I get user opinions on that?

...and then DeWalt had their version which picked up some bad reviews
and I think that was replaced with a new model so now I'm thoroughly
confused but looking for installer opinions on these type products.

Contact me "off List" if there's an extra scanner-gizmo available for
purchase or for lease. Thanks in advance. The Wrench List is the Bomb!
