    My second one of these
    With the line locked, I project a cross line on a wall or floor at a sharp angle. I project an unlocked vertical or horizontal line in the same plane with a second laser. Low points in the surface appear as waves in the locked line. simply fill the surface until the lines converge and the surface is perfectly level.

    Clever Idea / Good Value
    Ok, I havent used this too much as it is new, but it worked accurately out of the box, projecting a level laser line across a 30' room.

    This will come on very handy on my 3 current renovation projects.

    For the price, on sale, cant be beat.

    not sure of stablity of this product,
    Product seemed to rock on flat surfaces, unsure of swivel base. removed base from laser and it would of make better sense to have installed 4 buttons on bottom of laser for improved stablity

    I would buy this product again.
    This level is top quality, yet compact in size and in price. The compact size is actually a handy advantage -- it easily fits in most tool pouches or tool boxes or glove boxes. It shoots both horizontal and vertical laser lines.

    Accurate and Easy!
    Three different beams (vertical, horizontal, or both) to choose from. All accurate and bright. Ability to to mount via tripods, poles or via magnet. Super easy, durable and priced very well.

    Works well and saves time
    I've used this device to install shelving and it appears to be very accurate. Using a tripod is pretty much a requirement as you can't tilt the unit up or down beyond several degrees. But for the price, I'm not complaining.

    Can the horizontal laser line be projected higher or lower than the height that the unit is sitting on the tripod. In other words, can I shoot a horizontal line 6" off of the floor or 12" from the ceiling with the unit sitting 4' off of the ground on it's tripod?
    Home User on Mar 27, 2015
    BEST ANSWER: According to Bosch technical team, they do not offer a laser with the desired function. The laser beam will just project on the service and you cannot adjust the beam.
    can I aim the laser on the ground in manual mode to help line up grout lines between 2 rooms?
    Nick on Dec 22, 2014
    BEST ANSWER: Yes, but the laser would need to be mounted so it is facing down

    New Vs. Reconditioned

    What's the difference between New and Factory-Reconditioned?

    Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
    • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
    • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
    • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 60 days.
