Anyone have any specific knowledge/experience of ultrasonic measures?

Good for approximate measurements IME, not usually that accurate.

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.

The best ones are the Leica laser measures. But be prepared to spend
£200 ish for one of those.

Just searched the B&Q (bloody useless) site for 'ultrasonic measure'. Only
two results, B&Q own brand & Ryobi. I know they do B&D + Stanley, I've seen
them in there.

Specification for the Ryobi 'Stud Sensor & Ultrasonic Measure' icluded the
phrase "2 year warranty. Must be connected by qualified electrician".

Is inserting a 9v battery really covered by Part P?

Depends on where in the electrician you insert it ;-)
