Leica Geosystems 840384 NA520 Automatic Optical Level

This is a great level for construction projects. It is very accurate, easy to set up, and has better optics than any I have ever used. More expensive than other levels Amazon sells, but well worth the money.

Excelente calidad como lo q siempre a caracterizado a Leica

Good quality. Checked initial calibration using the 2 peg test, 1/16" off over a 140 feet distance. Easy to set up each time, for a spectacle wearer, i take my glasses off to sight & the magnification is great & focus adjustment with horizontal fine tuning is great. Exactly what i was wanting in a transit. Just have to call a friend to be the rodman each time.

Nice instrument but it came with the instructions on a 2.5 inch CD. I have nothing that can open it. Staples can’t open it and our local Word Pro couldn’t open it either. I wasn’t able to get instructions on line or from Leica. It’s not complicated but I’d like to have at least seen the instructions.

Works exactly as expected.

its a Leica of course its great

This is the NA500 Series, Leica’s mid-grade line above the 300 and below the 700 series. I’ve had the NA720 for 10 years With the 500 series 32x it is ISO certified for 1.6mm Std Dev for 1 kilometer double leveling. Anybody, such as the gentleman who found it to be a foot or two off in 100 Ft - this means your compensator is likely jammed. Read the manual and you’d know that. Any auto level is susceptible to this and it can be easily resolved. All that being said, this will be more accurate most construction work will require. Surveyors should get the 700 series. However, true first order leveling will require a grade of beyond these devices ($3k to $10k), and exceed leveling capabilities of 1” total station.

checked it with my gps and ts.... this thing was wayyyy off. it MAY run uphill with this thing

This Leica builders level is very accurate, easy to use and good quality. Very good value for the money. Much more accurate than a high value rotary laser... provided that the operator does their part, of course.

Precisie Gereedschap Leica !

Had the level 6 weeks , it’s faulty and fogs up inside camera when used first time last week . Contacted leica direct and they explained it was sent to USA May 2025 and returned. Sold to me as a new product but was probably reconditioned.

ENTREGA SUPER SEGURA PAGUE POR EMBALAJE DE AMAZON PARA QUE NO SE VIERA LO QUE ERA. PERO DE AHI EN FUERA NO TUBE NINGUN CONTRATIEMPO NI PROBLEMAS CON EL EQUIPO NI CON EL ESTADO EN QUE LLLEGO EXELENTE PRODUCTO Y EXELENTE VENDEDOR.

The level itself is very nice but I hate the case . It's very hard to open especially working outside where it's cold .
