Overview: The DeLorme Earthmate PN-40 is a versatile hand-held GPS unit that is ideally suited for hiking, biking, boating, hunting, fishing, and geocaching. It features a bright,
2.2" daylight-readable color screen. The PN-40 includes topographic, street, and satellite maps, plus nautical charts, to give you accurate detail as you navigate. It comes with a 1 GB SD Memory card
for quickly loading additional map data to your device.
Waterproof Design: The PN-40 conforms to IPX-7 waterproof standards with an
impact-resistant rubberized housing for a solid grip.
GPS Receiver: The PN-40 is equipped with a new, high-sensitivity, extremely fast 32-channel GPS Chipset with a dual core processor for fast map redraws when panning or zooming. The STMicroelectronics
technology and DeLorme firmware give you faster acquisition times and ConstantLock for outstanding satellite signal retention. The PN-40 is WAAS enabled to give you accuracy within 3 meters. It also employs a proprietary Kalman
filter for enhanced GPS accuracy.
Color LCD Display: The unit offers a 2.2" Sharp (brand) color TFT (220 x 176 pixels) backlit LCD display.
The display's backlight comes on whenever a button is pressed. You can set the backlight intensity incrementally between 100% (max) and 10% (min).
Power Requirements: The unit
comes with two "AA" batteries. The unit can operate on alkaline,
Lithium, NiCd, or NiMH
batteries. An optional PN-series power kit comes with a rechargeable Lithium-Ion battery, along with an AC wall charger and a 12-volt in-vehicle charger. The Device Setup page allows you to indicate
the type of batteries being used.
Internal Flash Memory: The PN-40 stores waypoints, tracks, routes, and the basemap data in its internal memory. An additional 500MB of internal memory is available for transferring
and saving maps in the unit. The PN-40 can hold up to 10 tracks with up to 10,000 points per track, and up to 1000 user-defined waypoints and up to 50 routes.
SD Card Slot: The unit features an SD Card slot inside the
battery compartment to load additional detailed maps. The PN-40 supports
high-capacity SDHC cards up to 32 GB; a 1 GB SD card is included, but adding a
larger SD card allows more map storage.
Built-in SD Card Reader: The PN-40 supports fast USB 2.0 data transfer to the internal memory or directly to an inserted SD card. For large map packages (over 350MB), using an
external SD card reader with your PC would be a faster download. It takes about 10 minutes to transfer a 350MB map to a card loaded in the unit, but it takes about 2 minutes using an SD card reader.
Included Maps: The Earthmate PN-40 comes with the full version of the newly-released Topo USA 8.0. The
included DeLorme Topo USA 8.0 DVD software gives you full, updated U.S. topographic and street maps to export as needed to the PN-40. You can transfer many types of data to the unit, including
satellite imagery, aerial imagery, USGS Topo Quad maps, and NOAA nautical charts. The unit has a pre-loaded world basemap that includes major highways as well as secondary and connector roads in the
Sensors: The unit is equipped with a 3-axis electronic compass with an accelerometer which allows it to work in virtually any position, while in motion or standing still. It also
has a sensitive barometric altimeter to give you reliable, accurate altitude readings.
Map Orientation: The PN-40 features a two-dimensional on-screen
map that can be set to one of three orientations.
- North Up: North is always represented at the top of the map screen.
- Heading Up: The direction in which you are traveling is always represented at the top of the map screen. The North arrow is shown in the upper right corner.
- Course Up: The direction of the finish of your route is always represented at the top of the map screen. The North arrow is shown in the upper right corner when
Find Button: You can use the Find button (indicated by a magnifying glass) to search for addresses, roads, cities, points of interest, waypoints, coordinates, and more. You can
search for a destination near the map center or by the location's name.
Mark Button: The Mark button (indicated by a push pin) lets you mark a waypoint at your current GPS location, or if
you're panning the map, at the cursor position. The waypoint is saved to allow you to navigate to it at a later time.
Geocaching: Geocaching is a popular hide-and-seek sport for GPS
users. The PN-40 allows you to locate and navigate to a desired cache, as well as marking the location of a cache you may hide.
Almanac: The PN-40 has a Sun/Moon page which allows you to
view sunrise/sunset and moonrise/moonset/moon phase information for your current GPS location. You can also see high and low tide information based on a specific time, date, and tide station. For
sportsmen, you can view a prediction of the type of day it will be, and the best times to hunt or fish.
