Good point about the add and subtract. Very valuable feature. The new Lite and Classic will be available in 2 to 3 weeks. It should be noted that the new Lite will not have the add/subtract/multiply feature. Leica has decided to make it a "laser tape measure". Point and shoot.
The new Classic is pretty slick. It has raised/enlarged buttons, built-in bubble level and 2x telescopic viewer. It also has "quick keys" for the pythagorean function, reference setting, and units of measurement.
As an appraiser, I would purchase the new Classic. It is a little more expensive but I believe that the add/subtract/multiply feature is a must. Also, the pythagorean function is very handy for straight walls where there aren't any targets.
I am selling the new Classic now. I will begin shipping them in a few weeks. If you want to see it, click on the following link......
