Does what it says on the tin [updated],
Verified Purchase(What is this?)
This review is from: Bosch PCL 10 Cross Line Laser Level (DIY & Tools)
I bought this in preference to the Quigo because the price (about £60) wasn't much higher than the Quigo's and the quoted range of the laser was greater. On reflection maybe the Quigo would have been a better bet, mainly because it has a built-in screen protector that snaps into place when you lock the device, whereas the PCL10 has the locking mechanism but no screen protector, just a soft carry case. It's a small quibble, perhaps, but in the real world carry cases get lost or damaged and I I can't really see why Bosch couldn't have built the protector in to the more expensive models. That said, the PCL10 is a decent device for indoor work. The laser line is about 1mm wide and is bright enough under normal lighting conditions. Both horizontal and vertical lines are always on (i.e. you can't select to have only one or the other), but this isn't a problem (at least, not to me). One thing that's a bit of a pain is that you have to get the device almost level for the auto-leveling system to work, but the best way to use it is on a tripod in any case. It would have been nice if Bosch had included some kind of clamp-equipped mounting device in the purchase price, but I guess they think you'll rush out and buy their ridiculously expensive tripods instead (rather than just getting a cheap camera tripod for a quarter of the price). Being a lone DIYer (i.e. I have to do everything by myself, as the wife is more of a hindrance than a help) I can say that getting a level with the Bosch is easier than doing the same with a spirit level or a water level. I have also seen a professional plasterboard installer do a rather clever trick using a laser level to get ceiling-mounted aluminium framework level, which involves tapping the frame pieces downwards until the laser beam just starts to reflect off them. Having tried to level similar framework using a spirit level I can tell you that it's very difficult, and I'll be trying the laser trick next time.
[Update, March 2015] Haven't used this a lot, but where it has come in really useful is (a) checking a floor for level screeding, and (b) checking verticals, when an installer was installing doors for us. For the floor, you put the laser down somewhere and measure the height of the red line nearby (it should be 5cm off the floor), then go around with your tape measure and measure the height of the red line in different places. It's very quick and easy, and shows problem areas better than using a spirit level, in my opinion. For the verticals, I wish I'd insisted on the installer using the laser from the start, because the first couple of doors were out of whack by a few mm, which was enough to notice, even though he's used a Sola level. The red line is plenty bright enough indoors, though of course it spreads wider the further away from the instrument you go. Overall, still pleased I bought this gadget.
