Anyone know about the Laser Trac 4 in 1 level at Sears?
I was thinking that it would be handier than a water level being used by one
On the box it says "accuracy + or - 1/2 inch at 30 feet".
I asked what this meant. Could a supposedly level line be 1/2" high at one
end, and 1/2" low at the other. Answer "I don't know".
Anyone give any help. If I think the line is level, and it's out of level by
1/2" on a 12' wall, the tool is worthless.
I looked on Deja news, nothing.
When reading the subject line/tool name, stop after the first word and go
look somewhere else.
I've traded, sold, junked every piece of crapsman I've ever had the
misfortune to buy, some without even using.
Just my 1cent worth.
1/2" is optomistic.
Everyone hear this. If it says laser level, and costs under 350 bucks, turn
and walk away. No, run away.
Not bright enough to be seen outside in bright daylight, and crazy
It means, measured a thirty feet from the level, that the line could be 1/2"
high or it could be 1/2" low. If they are stating this accuracy, chances are
it would be much better than that. it comes out to .016 per foot. That's
better than you will do with average spirit levels and much better than a
chalk line. The water level would still beat it though.
Used mine for a project today, did exactly what it supposed to do. I
don't know about the accuracy thing over 30', I haven't witnessed it,
but I also haven't worked in a 30' room either. For my house working
on my basement walls, other areas of house installing chair rail, etc,
it has done a great job. Got it as a gift, but I think they only cost
I doubt most folks really need to use a level on a 30 foot surface. I find
15' is the farthest I go. Since opinions are like belly buttons... one
thing to note is how good are your eyes? I'm blind as hell, so a laser or
chalk line is usually a better solution for me since staring at a bubble
oftens seems to to result in inaccuracy.
Good luck with it!
Why not check the laser's accuracy with the water level? I've never used one
of these, only the big lasers on tripod w/laser eye. One thing about it, the
laser is gonna be a straight line whereas the chalkline could fail in many
ways (bumps in the wall, somebody let the dummy end slip, etc.) Nothing more
fun than having multiple chalklines in one area. Hopefully you'll post back
here and let us know how acurate it really is.
You can do a self-check. Set up a level line where you can mark both
ends. Now do the same from the other end. The difference between the
two lines at the end where you started is twice the error in whatever
the length of your line is.
There are two types of errors. One is repeatability error, i.e. how
different is the position of the "level line" as you repeat the same
setup an number of times. The other is consistant error, i.e. the
level has a built in error of xxx over some distance.
You may want to repeat the above test several times to get an idea of
how much of each error you get. It's like target shooting. If a
rifle is perfectly sighted in, you still have a scatter of the pattern
(unless you, the rifle and the ammo are perfect). If the rifle is
sighted off in one direction, you still get the same size pattern but
it is shifted off center from the bullseye.
For what you're buying it's not bad. I checked at
ROBOTOOLZ who makes all sorts of laser levels
and their level that HomeDepot is now selling
for $249 is +/- 1/4" at 100'. I wouldn't use
the Sear's level to layout a large building or
something at least 30' away, but something
along a 12' foot wall or similiar seems to
be in its capability.
One of the magazines did rate this tool
as a good value. I think it was Workbench.
I'd go for it, if you couldn't afford the
better laser level.
Others, I'm sure will disagree.
FWIW I was just given one, and tried it last weekend while installing
some chair rail. Bottom line: it's getting returned.
1) The laser isn't bright enough. Even with the "laser enhancing"
glasses, in a moderately lit room it was darned faint 8' away.
2) The laser line is too fuzzy for precision work, in my opinion.
And the biggie...
3) I "leveled" it using the internal level. Was out a good inch over
8'. Maybe mine is defective, but this isn't even in the ballpark.
