Crossfire Auto Leveling Laser With Projected Level Line, Plumb Line & Cross Hair, Laser Line Is Visible At 40' With Accuracy To 1/8" At 20', Includes Innovative Wall Mount System With Horizontal Surface Base & Can Be Attached To a 360 Degree Tripod.
Throw out your chalk lines and trash your plumb bobs—-Crossfire is all you'll need. Just place it where you need it and the Crossfire levels itself for accurate straight, level lines every time. It's spendier than Black & Decker's Sight-Line model, but you do get more for your money, and its "cool factor" is high. First, it levels itself automatically, eliminating the need to squint at bubble vials and ensuring accuracy, something we've never been fond of. But what distinguishes this laser is that it projects two lines at once—-one vertical, one horizontal—-and the position of each can be adjusted individually. So if you need a square work area, the smooth rack-and-pinion mechanism will let you create it easily. We think this is the perfect tool for laying floor tiles or hanging a suspended ceiling. Once you've got your hands on it, you'll find dozens of uses around the house.--Kris Jensen-Van Heste

Summary: BDL310S Projected Crossfire Auto Level Laser
Comment: Shipped on time as promised. Took it to work (volunteer church construction) the next day. It is being used to install suspended ceiling. It can be hung on drywall with its unique pin device making it easy to layout the established height. I am very pleased with the product and its price.

Summary: .Should have bought this a long time ago.
Comment: Highly useful, highly accurate, and a professional tool. A real time saver also. Have used this tool frequently since I bought it. Sure beats the old fashioned carpenter's level.

Summary: Good amateur's laser level
Comment: Only 1 of the 2 lasers worked in the first unit I received in spite of the box being in good shape and the product well packaged. For the price, this is a very cool tool. The laser assembly hangs from the top of the housing which is how it autolevels. The laser lines spread perhaps 45 degrees wide. From 10', the horizontal line was about 8 feet long. The brightness is marginal outside in daylight at 10' but its useable early or late in the day. Inside is no problem. There's a tripod socket in the base but it's recessed so much that you need a long screw on your tripod. There's a hanging loop on the top and the bracket that comes with the unit has a vertical adjustment of about 4". There's another adjustment that pivots the unit horizontally. It takes some head scratching to figure out how to get it to do what you need and having a ladder to put it on is necessary if you want to use it outside with a high line. Not bright or robust enough for a professional but handy for the homeowner.

Summary: Cool tool...
Comment: Works very well around the house. I've used it for hanging pictures and some shelves.

One note: it doesn't seem to screw into my tripods (as other reviewers have noted) - the screw isn't long enough. I have tripods with both a 3/8" and 1/4" threaded screw. This level is 1/4", so I picked up a Manfrotto 015 3/8-Inch Female to 1/4-Inch adapter and the adapter IS long enough to screw into the level! So if you happen to have a 3/8" tripod, pick up this adapter (about $5 here at Amazon, or a good photography store) and it will screw into the base of the level!
