Got this today at the local Sears store. Price was $34.99. Two (2) AAA batteries required and are not included. It comes in a nice zippered case. Warranty is one year. The unit is plastic (not necessarily fragile, but not a Sherman tank), so it will need to be treated like a multimeter, a moisture meter, a thermal leak detector, or your high dollar stud finder.
Stated accuracy is +/- 0.1 degree. The unit also has bubble tubes, but after using this instrument digitally, I think mostly just to show how inaccurate bubble levels are.
It reads level and plumb and any angle in between. It has a percentage mode for plumbing or gutter fall. It also has Inch/feet mode for measuring the pitch of a roof or stairways. it beeps at 0, 45 and 90 (but can be silenced). It has a zero button for relative/absolute measurement. It has a hold button to freeze the reading (allows you to get a blind reading, hit the hold, and turn it around to look at it, etc.)
I purchased this tool for a reason, of course. I am beginning the assembly of my main work table. I have already modified a base cabinet to 38 1/2” height so that my finished top height will be 40”. The cabinet will be located on the back wall of my shop about half-way between the two side walls. The cabinet will be shimmed level with the world (not my concrete floor). I needed something to help accurately and quickly run wall cleat supports continuously along the back wall on each side of the cabinet. I want this table to be as flat and level as practically possible.
How did it do? This thing is awesome! It is (with my eye judgment) 5 to 10 times more accurate than any of my bubble levels. It’s a hell of a lot quicker (it is instantaneous), and I do not have to line my head and eyes up for visual judgement. The backlit LCD screen is very easy to see.
It is also magnetic, so I was also able to play around with attaching it to the top of my 2 and 4 foot steel bubble levels (piggyback) so that I could cover spans longer than the 8 1/4” length of the unit. Sweetness !
I like it. I like it alot. I highly recommend this digital torpedo level.
