After researching a lot of GPS units we Choose the
DeLorme Earthmate GPS PN-20.
This compact GPS receiver lets you create tracks of your travels, create routes, and find points of interest, and more!
I’ve been looking for a GPS device to show me not only a map with my current position, but show my position on aerial photography and satellite imagery. Think of this new type of GPS as having Google Earth, GPS enabled, in your pocket. The device itself is nice and small; it is very light making it easy to travel with.
I bought my DeLorme PN-20 as Bundle It came with a USB cable, SD card with Reader, two AA batteries, Travel Power Kit, printed user manual, and a copy of Topo USA version 7.0. Inside the Topo USA product is a coupon good for 400 sq. km of aerial data packets (ADP), which is where the aerial photography and satellite imagery comes from. I also purchased the RAM Motorcycle-ATV-Snowmobile Mount.
The outer skin of the PN-20 is a rubberized material, which makes the device easy to handle and waterproof. The buttons are tall enough and stiff enough that they can be used with a medium weight set of gloves.
Upon starting up the device the first thing I noticed was that the screen is very bright. The screen is a similar overall size to that of other handheld GPS devices with a resolution of 176×220 pixels. I didn’t have any trouble viewing the display in bright sunlight conditions.
When you turn on the unit it only takes about ninety seconds to fix on satellites. Not too bad at all for a 12 channel receiver (STMicroelectronics) Note: The receiver is WAAS enabled. Like normal satellite views the height of the bar indicates the relative strength of the signal from that satellite. The color of the bars will change based on other information from the satellite. If the bar is red, information from that satellite is being received, but not yet used. Green means that satellite is being tracked and data is being used. Blue means the satellite is being tracked, data is being used, and WAAS correction information is being received from that satellite. You can also disable the GPS reception to save on battery life while setting up your trip on the device.
The map page is where all of the action happens on this GPS. You can choose if you want to view Aerial Photography, USGS Topo maps, DeLorme Topo maps, or Satellite imagery. There is also a base map, which displays major roads of the entire world. (Nice!) You can also pick which order you would like to layer the maps if your highest priority type of map is not available in the current view.
I’m really excited about the map views on this GPS. After all there are not many GPS products on the market like this one.
One more thing, if you like to Geocache this is the device for you.
