The fully-automatic, height-adjustable PRA 90 tripod simplifies and speeds up horizontal levelling and alignment. Thanks to an automatic height-adjustment range of 97 to 190 cm that is adjustable via a remote control, the entire levelling operation may be carried out by one person. The lithium-ion battery-powered motor in the tripod legs lends extreme sturdiness to this new product, which is compatible with all conventional rotating lasers. Furthermore, the tripod is built to keep out dust and rain, thus proving to be an efficient and reliable companion for levelling and alignment work on construction sites.
