But cheap buy twice, get the Bosch gtl3 if your gonna get one, personally I'd invest the money in the biggest straight edge I could get hold of, laser lines can be a big hard to spot unless you block out all the light
Ive had grumbles about the quality of carb blocks lately with my supplier as they are cheap far eastern ****e, doing my head in having to buy them constantly for doing the edge of anhydrite grinding, the blocks are not compressed enough and rub down to nothing to quick, they never used to be like that, probably will just invest in the metal grinding edging plate thing from janser
I've got the Bosch which projects 3 lines had it for over a year now and very accurate. Set out 800 Sam of carpet tiles with it and spot on. Not cheap tho about £200. If you get a cheap one it won't be accurate and if your doing a large area 2 mm difference and your line will run big time on a 8 m length.
I love new toys and I've seen these Bosch lasers in Actionion but do I really need one ? Obviously I want one but how beneficial are they for my average job say a 40m2 lvt ?
