Magnavox Introduces New Low-Cost Speed Log —Brochure Available

The MX 720 electromagnetic log, a compact unit delivering reliable speed-through-the-water measurements, was introduced recently by Magnavox of Torrance, Calif.

A brochure is available describing how the MX 720 operates either as a stand-alone speed log, or interfaces with equipment requiring standard speed inputs such as s a t e l l i t e navigators, ARPAs, and true-motion radars.

The system consists of a small, remotely located electronics unit, a speed indicator graduated in 0.5-knot increments, an odometer displaying up to 9999.9 nautical miles, and a through-the-hull transducer easily installed through a standard 2-inch gate valve. The transducer extends only 2 inches beyond the hull, virtually eliminating any problem with debris fouling.

The new Magnavox speed log can be calibrated quickly and is designed for unattended operation and minimal maintenance.

Up to four additional speed indicators can be added at the user's option.
