I posted this a while back:

ISTR Zircon being mentioned here before as being the only type worth

fairly soon, where I believe they're about half the price they are here,
so I might just avail myself of one...

....the replies indicated that the Triscanner Pro was definitely the
one to go for.

Anyway, I'm now posting from across the Pond and have called in to a
"Home Depot" looking for one of these. They don't seem to sell them,
but have a considerable other range of Zircon sensors, including their
Multiscanner i500 OneStep for 20 quid, or the i700 OneStep for 25
quid. These are evidently 'higher' spec than the Triscanner Pro, and
as far as I can see from the blurb on their website, seems to use the
same technology??

So I'm just wondering whether anybody has tried either of these
Multiscanners and can vouch for them?

One thing which worried me slightly (from the link above) is mention
of erasable marker tips which you can order from customer services in
the US (read: unobtainable in the UK!) so I wonder whether the device
will work OK once the supplied marker tip has run out?

Thanks a lot

PS - I know everyone hates a smug ******* (me included) but just take
a look at the view from my window today:
