ZIPLEVEL PRO-2000B High Precision Altimeter  with 75-Feet Cord and User Guide
The ZIPLEVEL PRO-2000B is essentially a PRO-2000 with a shorter Cord and no accessories. The less expensive PRO-2000B comes without a protective rubber Boot, Unipod or Stakes and has 75' (23m) of Cord that covers a 150' (46m) circle. Each of the ZIPLEVEL accessories can be purchased individually and we recommend buying the protective rubber boot, particularly for outdoor work.
