DOT-Z1 Basic Distance Measuring Instrument (without GPS)

Note: The DOT-Z1 Basic is non-GPS based instrument, as such it requires additional wiring to a VSS source.

DOT-Z1 Basic is a versatile vehicle mounted DMI (distance measuring instrument) offering the most complete set of operating features.

The most commonly used features are:
  • Measures precise distance in feet, miles, and meters.
  • Measures precise speed in mph, fps, and kph.

The instrument utilizes new and improved algorithms for greater accuracy in measuring distance. A high performance microprocessor and solid-state circuitry make it reliable and impervious to interference and noise in a typical automotive environment. Unlike other DMIs, the DOT-Z1 does not need an external sensor to operate, making installation easier and lowering costs and maintenance.

Infinite expansion capabilities and utilities are offered via vast set of signals for peripheral equipment such as printers, laptop computers, paint marking systems, and remote controls. We offer customizations for suit almost any task or application for a nominal fee.
