TRUE SAFETY IS KNOWING YOUR TRUE SPEED

Take the guess-work out of knowing how fast or slow your vessel is moving. Know your precise speed anywhere with the Marquardt Speed Log.

Based on the pulse doppler sonar principle, this new generation speed log measures your true speed over the bottom to 800 feet depth. What's more, by having precise speed readings, it provides a con- tinuous performance check for greater savings.

The Marquardt Speed Log is also an aid to dead- reckoning navigation. Its accurate velocity meas- urements are relative to the ocean floor in channels, harbors, coastal waters and for docking.

To get the full story on this precise speed log, contact Marquardt today. urn
