The Only Wristwatch GPS Navigator

Ideal for backpacking or canoe trips, this global positioning system (GPS) is built-in to a compact wrist watch. Despite its tiny dimensions (60% smaller than other GPS devices), it operates as effectively and precisely as a larger system anywhere on the planet. Shield layers prevent electrical interference between neighboring circuits, yet still enable the sensitivity necessary to receive transmissions from the twenty-seven GPS satellites in orbit. Its eight-channel receiver tracks up to eight satellites simultaneously, ensuring accurate latitude and longitude readings in as little as four seconds. Almanac data from satellites is stored in the device, and used in conjunction with preset area and time data to expedite position determination. A navigation feature allows the user to input a destination, whereupon the GPS will graphically indicate the direction and distance from the starting point to that location. It has storage capability for up to 200 waypoints, and up to 100 points of continuous route data which will provide a graphic display of a route to take back to a starting point. The unit's computer chip picks up GPS transmissions on a mere three volts of power. The single lithium CR2 battery (included) allows up to 600 single readings, or approximately ten hours of automatic monitoring with readings updated once per minute. Incoming GPS satellite data also ensures that the watch keeps accurate time. The watch also has an alarm, day, hour, minute, second and AM/PM display, automatic time correction by GPS and area, and Daylight Savings Time on/off. Face measures: 2 1/2" W x 2 1/2" L x 1 1/8" D.
