Walker 7070 Log Only is a Speed Log System providing electromagnetic log data from a single processor.
This compact, cost effective system takes advantage of “state of the art” electronics to process the log sensor input, outputting digital data on a single NMEA 0183 data bus to DIN 144 data displays.
Walker 7070 electromagnetic log is designed for vessels above 500GRT, offering both forward and astern speed, with ranges from -0 to 80 knots full scale. It is suitable for vessels varying from patrol boats and ferries to liners and bulk carriers.

- Full sensor compatibility with Walker log systems.
- Digital display to DIN 144 for log speed and distance travelled.
- 4 point speed log calibration.
- NMEA 0183 interface to systems.
- Ease of installation, use and service.
