DeLorme describes its Earthmate GPS PN-20 as the only handheld GPS that can display DeLorme maps and aerial imagery. The company says the all-in-one color-screen GPS and mapping solution doesn’t require an additional mapping software purchase or subscription; DeLorme’s Topo USA 6.0 DVD software is included with the device, with detailed topographic and road maps of the entire United States, available aerial imagery and a broad range of GPS capabilities.

With its waterproof rubberized housing, the Earthmate GPS PN-20 is designed for rugged outdoor use. It measures 2.43 inches wide, 5.25 inches high and 1.5 inches in depth, and weighs 5.12 ounces, with an ergonomic design and large, accessible function keys. Its high resolution (220 x 176 pixel) transflective color screen is designed to deliver exceptional visibility under a wide variety of conditions, including direct glaring sunlight. The 12-channel, NMEA-compliant receiver includes STMicroelectronics chip technology with SiGE front-end noise reduction, plus DeLorme firmware for faster acquisition times and improved signal retention.

Topo USA 6.0 works with Microsoft Windows Vista, as well as Windows 2000 and XP. Six map types are available, including a world base map, U.S. streets and topographic maps from Topo USA, regional routable maps, free downloads of scanned USGS quad maps, black-and-white aerial imagery, and colorized satellite imagery. In addition to nationwide map coverage, the receiver comes preloaded with a worldwide highway/major thoroughfare reference base map.

The Earthmate GPS PN-20’s intelligent data layering feature is designed to allow users to easily toggle between maps and aerial imagery of the same location. When GPS tracking on an uploaded road, an audible signal warns of upcoming turns, and there is a back-on-track feature should users go off course while driving along a route. On-device road routing also is available, with back-on-track and turn alerts. The device is WAAS-enabled for accuracy within meters, and with its proprietary Kalman filter, the Earthmate GPS PN-20 also addresses the complex problem of reflected GPS signals.
