Furuno Introduces New Low-Cost, High-Performance Loran Navigator

Furuno USA, Inc. has recently introduced a new loran navigator, LC-90, which is housed in a rugged diecast aluminum case and provides all the features necessary for safe and efficient navigation aboard any size boat, ranging from freshwater bass boats to the largest worldcruising yachts. Reportedly, the unit's performance matches or exceeds even the most expensive loran C receivers on the market today, yet it is inexpensive and compact, measuring 11 inches wide, 5.75 inches high and 3.5 inches deep, including mounting bracket. The LC-90 weighs 6.4 pounds.

Sealed membrane touchpads provide positive, splashproof control of all functions displayed on the large five-line liquid crystal display (LCD). Both touchpads and display have variable back-lighting for nighttime operation.

Once local position has been entered, operation of the LC-90 is completely "hands-off." It automatically selects the proper GRI and optimum slaves, compensates for ASF to give accurate latitude/longitude readout, compensates for local magnetic variation for accurate magnetic bearings, and sets the six internal notch filters to eliminate interference. If desired, these automatic features can be manually overridden by the operator.

In addition, entry and readout for all position functions may be either Lat/Lon or TD, making Furuno's LC-90 extremely simple to operate.

The LC-90 is highly sophisticated.

For example, with 100-waypoint memory and route planning capability, up to 10 individually designed routes can be entered (each consisting of up to 10 waypoints) and the LC-90 will automatically guide a vessel along the programmed course. It will compute and display range/bearing from present position to any waypoint or between waypoints, crosstrack error, course offset and steering indication.

It also has off-course, border, arrival and anchorwatch alarms.

Additionally, the unit will compute and display speed and course made good, velocity to destination, time and distance to go, plus complete loran system status information.

Connecting to other onboard equipment is simple and straightforward.

The LC-90 has a built-in interface that provides Furuno CIF output for course plotters, printers, sonars and color video sounders; NMEA 0180 simple format output for autopilots; and NMEA 0183 complex format output for plotters.

The LC-90 will operate from any 10-42 VDC power source and draws only 9 watts. It comes complete with antenna coupler and cable, installation material and basic spares.
