ZIPLEVEL PRO-2000B High Precision Altimeter. This is a high precision level. I bought it several years ago to level my pier and beam house. Worked perfectly. This level can measure the thickness of a business card. It has .005 precision. It comes with an aluminum padded case, a mono pole, the rubber case for the hand held unit, the instruction manual, and a 9 volt battery. I somehow damaged the 75’ hose that hooks the two pieces together. I sent it to the factory in December of 2019 and they recertified it to factory specs. I used it since then so I know it works as it should. Be sure to read the instruction manual before use!! The hose is delicate and needs to be handled carefully!!
