ZIPLEVEL PRO-2000 High Precision Altimeter Cord and Display READ DESCRIPTION

Description

In good condition with minor scuffs and scrapes from usage. It works, however the last time it was recharged was many years ago so the display reads out "Cord" every few seconds. It will likely need to be serviced to get the fluid refilled. Please see photos for details.
ZIPLEVEL contains a proprietary hydrostatic liquid and pressurizing gas. Like the air in pneumatic tires, the proprietary pressurizing gas will diffuse out of the elastomeric cord over a period of about three years. When ZIPLEVEL needs a gas recharge or in the unlikely event that its tough Cord is cut or punctured, "Cord" will flash on its display. If your ZIPLEVEL or Compulevel has not been damaged and is flashing "Cord" it may be possible to temporarily continue use by frequently rechecking your measurements and zero reference for repeatability. If damaged or if flashing "Cord", ZIPLEVEL must be returned to the factory for service.
