Need to buy a rotary laser level system.
Hi, I want to buy a used or new rotary laser level system to use around the farm, I’ve got some plastic drain tile to install with a trencher – couple of drain tile strings at 300 feet each, got a septic system to install next spring, misc other projects that I am tired of renting a laser for $60 per day. I see some on ebay, topcon, spectra, dewalt, hilti, etc…the dewalt can be had for a $200 or less, maybe a well used topcon for $300-400. What is the lowest level of accuracy I should get – some are 1/16 th at 100 feet (the best) some are 1/4 inch at 100 feet (the worst). I dont do this type of stuff for a living, so I just need a individual use unit, nothing fancy…..where do I begin, what models are good/OK – what do I have to look out for?
Thanks!

Welcome to BT and watch out for a guy named Bosshog, hes got GREEN envy and because of that he's kind of ornery to guys that are fortunate enough to own a John Deere!
If you go into the Tools column you'll see a lot of discussions on lasers and their uses, give that a try, you may find some valuble info there.

black and decker had one at amazon for $150 that look good.
First decide if you need the "slope" or "grade" feature, not all lazers have it, it would allow you to set the slope of the dig at the transit and then dig to the transit line.
Technically the difference between the "level" and "transit" in systems but the words are used interchangably way too often.
Transits are more expensive. I looked at a good Topcon early last yr. that had a inexpensive version of the "slope" system, costs new almost $1000 with stand, reciever case etc.
good used ones are available on e-bay , craigs list and from most factory dealers and service centers.
I just got the Stabila rotary manual-levelling for Christmas for a current job; I'll know in a bit how it works. On sale for ~$100 off at Amazon takes it to around $300. Comes with a detector.

I had the Stabila that's ~$500 and it was no good--beam so dim you could barely see it. I think it just had a bum diode and sent it back, but didn't buy another. Let me know how yours works out.
For what you describe...I would look for a laser with a grade feature and the capability to shoot up to 500' or more with a detector.
These run around $600+ new.
Or..call the Soil Conservation Service ( now Natural Resource Conservation Service) to engineer your tile drain systems.
You can always sell it when you run out of projects!
We have a $1000 older laser and the $450 Dewalt. Both work fine for the septics and sandmounds we have installed.. I have a friend who uses a cheaper rotary, also works well.
$1K will get you self leveling and $1.2K will get you slopes these days.
edit - I am referring to using it with the detector and a rod - neither laser is particularly visible outdoors.

To do 300 foot runs, you will not need any thing more than a 350 foot range, even if you want to do it in one set up. If your not going to use it frequently, manual leveling is fine. If your decent at math, you don't need the slope/grade function. If possible get one with "out of level" shutdown. It is a real pain to have it get off level, and find out only at the end, with no idea of where/when it got off, and where you need to start the redo ( from the lessons learned file).
Be sure you get a good detector, and rod. I prefer a direct reading rod, as it saves on the math. I am pretty adamant about the crews at work using them because I am more comfortable that things will end up at the grade I designed them at.
For personal use, I have an inexpensive Porter Cable unit, that I got on sale (50% off), at HomeDesperate when they were switching brands, and a really high quality LaserLine Rod (cost more than the level). When I was doing land development I used it daily for about a year to check grades, and pad elevations.
At work we have Sokkia, and Topcon laser levels, and I have a Sokkia Total Station.
Any of the major brands is going to be of a fairly high quality, and reliable. You need to focus on what features you need/want. For accuracy it depends on what kind of slopes your dealing with. 1/4-in / 100-ft is generally good enough for most common work at short ranges. You said you were going to lay runs of 300-ft. Is 3/4-inch of error going to enough to cause a problem? Would 3/8-inch of error make it better?
