The Shop Force Laser Level is...well...a laser level.

Use it as you would a regular bubble level, or turn on the laser and use it for distance work like putting in a foundation or installing WDV pipe.

It measures 16" long, not including the switch/tailcap assembly for the laser. It has a ruler printed on the side, reading 0" to 15.25".


SIZE



Use this as you would any standard bubble level. Set it down somewhere and see if the bubble in the glass vial is centered within the two markings on the outside of the vial. If it is, the surface is level. If it isn't, the surface is not level.

To use the laser, turn the red knob on the end clockwise (as if tightening it) approximately half a turn until it goes down slightly and "locks" in. Turn it again clockwise (approximately half a turn) so the knob extends slightly and "locks" in to turn the laser back off.

I'm not a carpenter, and I don't play one on TV or on the internet, so please read the instructional leaflet that comes with the laser level for details on how to use the level for distance use, laying pipe, etc.

Claimed accuracy of the laser beam is a maximum deviation of 0.20" at 50 feet.



To change the batteries, unscrew and remove the red cap at the end of the level, throw it in the {vulgar term for toilet}, yank that silver handle on the front of the cistern down, and flush it away...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

If necessary, tip the two used AAA cells out of the level and into your hand, and dispose of, recycle, or recharge them as you see fit.

Insert two new AAA cells in the opening, flat-end (-) negative first, and screw the red cap back on.
Aren't you glad you didn't flush away that cap now?

Measures 21.1mA on my DMM's 400mA scale.



This is a laser level, not a flashlight meant to be thrashed and abused, so I won' try to drown it in the toilet, smash it against a concrete sidewalk, throw it against a wall, stomp on it, sit down hard on it, or otherwise abuse it. So this portion of the web page will be more bare than this section of the web page on a page about a flashlight.

The beam does have some artifacts in it visible from close range, but at longer distances (10 feet or more out) and in normal room illumination, these artifacts aren't bothersome or even noticeable.

I set it at one end of the house so it would shine to pretty much the other end (appproximately 40 to 50 feet), and observed the laser spot. The laser spot was pretty much on par with inexpensive red laser pointers; consisting of a central hotspot with two striped bands extending from its sides. You don't see this configuration when you're on the laser level side of the beam, but do when you're standing where the beam spot is shining.

As I said before, I'm not a carpenter, and I don't play one on TV or on the internet, so please read the instructional leaflet that comes with the laser level for details on how to use the level for distance use, laying pipe, etc.
