Bosch GLL2-80 Laser Level - Reader Review (Richard K.)

If you recall, a bit ago we ran a contest where we gave out ten new Bosch Dual Plane Line Lasers to chosen readers so that they could review them for the site (our original review is here). We encouraged them to be hard on the tools and to be nothing, if not honest in their assessment. The selected readers ranged from tradesmen to DIYers. We asked that they also rate the laser on a scale of 1 to 10 (10 being best). Here is the first review...


bosch_laser_RK.jpgI received the Bosch Laser Level the other day as promised by those kind hearted souls of The case was extremely big and bulky for such a small device, but once I opened it, I was told my eyes lit up as though it was my favorite holiday. By the way my favorite holiday is any day I get to open free tools. I played around with the Laser Level for a few hours. It has a very rugged design and the built in alarm definitely lets you know when you're not holding it level. Around the house it worked perfectly. It easily demonstrated how badly my picture hanging ability really is, but out in the field is a whole different story.

Here's a little background on myself. I am a Certified Master Plumbing Contractor in the State of Florida. I have issues with makeshift plumbobs and Electricians who already own Dewalt laser levels and love to show Plumbers up in front of their customers. Fast forward to now and I am only mildly bitter about the incident with the Electrician. The Bosch Laser Level comes with a magnetic attachment so I was able to stick it to the metal studs and a ladder at one of our jobsites. The Laser has a very bright beam even though the photos I have taken do it no justice. Shooting a horizontal line across all the studs is great because it eliminates the time it normally takes to measure and mark each individual stud to drill through when running our water piping in walls. As for drains and waste arms, it works equally well except its...well...level. Our drains and waste piping are supposed to be at a 1% to 2% slope for gravity drainage. That's not happening with this tool.

bosch_laser_RK1.jpgThe other plumbing type use I was able to figure out for this piece of equipment is that it works well for shooting vertical lines from existing roof vent penetrations onto new wall top plates, thus eliminating the need for the dreaded makeshift plumbob I can never make work. This level also seems good for replacing the chalk line when tiling showers and baths.

As for a laser level, I give it 8 out of 10 gold stars, hammers, or whatever. Its rugged, well designed and a complete necessity around the jobsite. From a Plumbers' standpoint, I give it 5 out of 10 whatevers. It's not 100 percent necessary for the trade but it does make a few simple tasks much quicker. I plan on keeping the Bosch Laser Level not only because it is a beautifully free tool, but the next time I see that Electrician with the Dewalt Laser Level, I can show him that mine is bigger.

I just picked up a Stanley auto-leveling cross laser. Used it for lots of things including recently siding on my 30x30' garage. Started at one corner and drew a line all the way around the garage. When I got back to the original corner, I was off by less than 1/16th of an inch. For under $100 that was worth it.

...but full 360? Sweeeeeet!
