Bosch GLL2-80 Dual Plane Line Laser- Review

bosch_level_hero.jpgWe break our lasers down into two groups; the big tri-pod style rotary lasers, descended from transits, and the little jobsite ones like the fantastic PLS2. Each of these styles has limitations though; the rotary lasers, while they can project a 360 line (meaning a line completely around the level), are large and awkward to use; and while the little guys are barely bigger than a juice box, they can only project a line out in front of them, so they constantly have to be shifted around the room in order to complete some tasks.

Bosch with their new GLL2-80 actually combines the good from both styles of lasers. Now, for the first time, you can get the 360 line, both vertical and horizontal, in a small package.

bosch_level_hero2.jpgThe technology here is actually very interesting. In a normal 360 level, the laser itself spins, and it's this additional mechanism that leads to their bulky bodies. What Bosch has done to get around this is to utilize something they call Cone Mirror Technology. What happens is that the laser shines against a little reflective cone which then projects it out 360 degrees. Our guess is that the little cone is about as finely machined of an item as you're going to find in any tool. With this set-up in action, Bosch has found a way to deliver the 360 laser in something that's barely larger than a pocket dictionary.

bosch_level_on_stand.jpgThe GLL2-80 has a number of smart features beyond the whole 'shoot the laser at the cone' thing. First off, it can be used in any one of three modes; horizontal line, vertical line, or both simultaneously. You also have the option of locking the leveling pendulum, so you're able to work in crooked, saggy houses like ours where level is less important than straight. The Bosch level shuts off automatically in 30 minutes, but you can override that if you want, and it also makes a little squawk when it's too far out of level, but you can override that as well. When it's off, the pendulum locks into place so there's no risk of damage during transport. There is also a mode that assists the laser in getting picked up by a remote receiver (not included in all packages).

There is also a little stand for the tool complete with an adjustment knob, so you can set it up and then tinker with the height of the level. The functionality of this stand is fantastic and we were able to really fine-tune the laser height to exactly where we wanted it.

bosch_level_top.jpgThe one minor detail that we wished was different is the on/off slide switch (the red one on the side). Unlike the PLSs, Bosch went with a hard switch (PLS's have soft-touch buttons), so it's difficult to switch the tool on and off and keep it stable at the same time. We've been on sites where we leave our laser set up in one spot for days on end and we practically build a razor wire enclosure around it so it doesn't get bumped. Keeping the level stable makes turning the laser on and off every day an operation like Indiana Jones fiddling with the statue in the first scene of Raiders. We're not saying this is impossible with the Bosch, it's just more difficult.

But that's a minor quibble when placed against the positives of this laser. Normally to get this kind of functionality you've got to use something the size of a watermelon. So what does this all mean to you in a functional sense? Well, it means a single laser set up for an entire roomful of wainscotting. It means no more setting up your laser in the corner to try to get the most coverage out of it's limited beam. It means one click and you can tell that your kitchen floor is two inches out of level fron the sides to the center (we're serious on this one), it means knowing exactly where the entire face of a new partition wall will land. it means a lot of things, all of which translate directly into more a more efficient work day.

Bosch_level_in_case.jpgThe bottom line is that Bosch has once again stuffed big tool functionality into a small tool body (remember their PS21?). And then there's the price. It's looking like the GLL2-80 is going to retail in the $300 range (which is just a bit more expensive than the 180 cross line PLS). To say that this is a very good price for this item is a bit of an understatment.

Case and clamp, yes. All part of the price. And it is expensive, but also very useful.

I believe in all things Bosch..nothing but the best. But, it looks expensive. Is case and clamp all included for that price?
