The ZipLevel Unipod Adapter ZLU-ADP makes your life easier when taking precise measurements with your ZipLevel PRO-2000 or PRO-2000B altimeter. Taking drop ceiling measurements or floor measurements in the top end of the ZipLevel's high-precision range requires much less effort. This monopod bracket attaches to the bottom of your ZipLevel unipod (sold separately), and provides a base for it to stand upright when fully extended. Included in the package are a corrosion-resistant aluminum bracket (3.8”L x 1”W x 0.7”H), thumb screw, lock ring, revised rubber foot, and acorn nut. The unipod adapter is designed to fit in as usual when your unipod is collapsed and put away inside the ZipLevel base unit.
