After a few days use of the Bosch DLR 165 Rangefinder, I'm convinced that it deserves a place with the trusty Fat Max measuring tape. The nice digital readout is great for compensating for age related eyesight difficulties or memory problems. Main reason I bought one is because I have been cutting an occasional board exactly 1" too short and after climbing down off a ladder can't remember the exact tape measurement I just made. It may be something of a crutch for us old timers, but for you young bucks it could also be a real time saver. The length, area, and volume are really nice for laying out framing. The inside measurement feature is great for getting rough openings to behave. Doesn't take much of a learning curve. Only took me a half hour to master the controls, so you texting geniuses can probably do it in a minute. Sources are the usual, Amazon, CPO Bosch, maybe some box stores. The wallet pain vs. utility factor is quite good, i.e., there are a lot more expensive and less handy tools out there.
