They are awesome aren't they! The one I use (Disto Plus) has a
built-in 2X telescopic viewer for longer distances and Bluetooth so you
can transfer you measurements wirelessly to a PDA or Tablet pc with
Bluetooth and sketching software. Until you try this out for yourself
it is hard realize just how much time you can save while on site.
The Stanley TLM 100, TLM 200, TLM 300 are made by Leica for Stanley in
Austria and are true laser measuring devices, as are all of the Leica
Disto products. They are not ultrasonic devices with a laser pointer -
yes even the $99 TLM 100 is a true laser device. Again, look at the
specs at www.laserstreet.com or other sites (just search on Disto or
Stanley laser meters).
For the rest out there: it does take a while to get use to measuring
with one of these. But once you are use to it you will find that it
will replace your tape for many situations but not all. I personally
keep a tape in my truck but have not used it at all in the last 6
months. Again, I do house measurements inside and outside for
appraisals, floorplans and as-built surveys for contractors and with a
+- 1/16th of an inch accuracy, I have found that I couldn't live
without it. I have cut my measuring time in half with it - not on
the typical rambler but on complex layouts and houses in the 4,500 SF
and higher category, especially the 9,500 SF house I did recently.
