rotary lazer level

[tupmaster]

looking into buying a lazer level ive looked on ebay and seen what appear to be similar products but vastly ranging in price has anyone any recommendations.
wanting it for various ground works around the farm including fitting receiver to the dipper arm on excavator for levelling ground and drainage work
does green or red lazer make any difference
thanks in anticipation

I’ve always used spectra or Leica, they aren’t cheap though. Definitely get a red beam laser

Had a basic Topcon 1 (just sold it for £100+vat), now have a dual grade Leica.
Both very good lasers.

Have a topcoat RL -H5A single grade laser, bought the cheapest kit available which came with the LS80L receiver which is fine. If buying again would have bought same kit with LS 100L receiver as the distance from grade display would be of benefit for stuff i am doing (shed foundations, drainage, concrete forms, sub bases etc).
5 year warranty with unit and recognised manufacturer.
Did look at the ebay lasers but figured that back up wouldn't be there if any issues so although cheaper initially may not have the longevity of other makes.

If mounting on excavator dipper different receivers can be used which have a wider reception for laser than standard receiver which needs to be face on to laser to pick up beam.

Green laser is easier to view in day light but is more expensive to manufacture.

I’ve a Datum machine control receiver it’s alright and will get you close when digging trenches etc due to being on the dipper. If you want to be within +/- 10mm you’ll need someone with the staff n rod eye, I also have a bracket to fit the grading bucket to put it on and it’s pretty good on that as it always sees the laser !.

Anybody used imex lasers? They are definitely keen on price and high on spec, 5 year warranty aswell, good enough for farm use?

Never used them nope. Check the technical data, if it’s a accuracy of around 1.5mm at 30m you’ll not go far wrong

They advertise 2mm in 3m , is that ok ? the more expensive models are down to 1.5mm in 30m i see.

so thats like 20mm in 30m then

Na i missed a 0 as you well know

Markovitz builders merchants do the 88r which is 1.5mm in 30metres at £500+vat and that's dual grade aswell

2mm in 3m is awful 2mm in 30m is ok though

Always fancied one, but probably can’t justify. So interesting thread.
Question, what does dual grade mean?

Single grade means you can set it to fall from north to south. Duel grade means it will fall north to south and east to west, so you can make south west corner the lowest. If that makes sense

The Trimble/Spectra, Leica Rugby and Topcon units are all well known, respected brands. All fairly much the same quality and price per spec. bracket.

The biggest question in my mind about the ‘cheapies’ is how absolutely accurate are they to begin with and how well do they stand their calibration over time.

Not sure some of these cheapies have been around for a long enough time to answer the second half of the question...

They should be re calibrated every 6 months anyway

I’d be shocked if ANY rotating laser levels used by farmers EVER made it back for a calibration let alone every six months.

I usually check mine myself and if they’re ok don’t send them away. Usually once every 12 month mine get done

How do you check yours?

I was told to stand it 20+m back from a wall, mark it, rotate laser 90°, mark again and repeat. If all 4 marks are rough enough then crack on?

Yeah mark on a wall about 10m from wall, rotate 90 degree and do it again, then move to 20m away and keep going for as far as I can
