I have the very simple Leica DISTO E7100i and I love it. It does have the Bluetooth feature. But I tried it and found it was not worth the hassle. It takes me around 1 hour to measure an entire house and sketch the dimensions on a piece of paper. When I tried using the Bluetooth for the dimensions it just took that much longer. Yes it would be nice to walk out of the measure with a done as built drawing in SoftPlan. But I rather just take measurements quickly and get out of my clients house to come back to the office and put them in. That usually takes less than an hour. So it just has not been worth it for me.
But I love how small the Leica I have is that makes it very easy to use and carry around. I have 3 of them and leave it in each car.
