Anyone have any specific knowledge/experience of ultrasonic measures?

I'm looking for a simple accurate way of measuring things like door frames,
alcoves, cupboard interiors etc rather than complete rooms.

Most seem to have a minimum range of 60cm which is fine, maximum range
whatever. Like one with a laser pointer to make life easier.




Take 2 strips of 50mm doorstop timber, less thah the alcoves you want to
measure. drill a hole for a bolt some way from the end of one. cut a
slot along the length of the other to take the bolt. use a bolt with a
wing nut and assemble. put into alcve and slide so that the ends are
touching the sides of the alcove. Tighten the wing nut. You now have
an accurate measure of the width of the cacove which you can transfer to
the timber you need to cut
