Performance
- Blazing-fast, high-sensitivity 32-channel STMicroelectronics Cartesio chipset
- Dual-core processor for instantaneous map and satellite imagery redraws, even with large aerial imagery files and multiple maps layers
- 360° raster rotation sets the PN-40 apart from other common GPS handhelds. With 360° rotation road, building, and other images really are on your left or right as you look at the map and walk, bike or drive
- 3-axis electronic compass with included accelorometer performs when held in any position—while in motion or standing still
- Sensitive barometric altimeter for reliably accurate altitude readings
- WAAS-enabled for accuracy within 3 meters
- Now supports SDHC high-capacity SD cards (up to 32 GB) for fast and direct map transfer from the included maps discs
Maps
- Comes with three discs containing detailed hybrid 1:100k topographic and street maps of the entire USA. You do not need anything else to hike, geocache, or navigate the backcountry. It's all in the box.
- A $40 certificate is included for downloading sample supplementary datasets. Take a "test drive" with any of the supplementary datasets DeLorme offers: high-resolution aerial imagery, USGS 7.5-Minute Quad Map, NOAA Nautical Charts, and more..
Pros
Color screen with the ability to load and view aerial and sateliite imagery. Quick access buttons make marking waypoints a cinch.
Cons
No good bike mount for this unit. Small buttons can be difficult to press with gloved hands. Trip start and stop functions are buried in on-screen menus. Serial USB connection is super slow - plan ahead if you're loading satellite imagery before a ride.
Verdict
This is a good all-around GPS for outdoor enthusiasts and does quite a bit out of the box with the included Topo USA software. Routing on trails works well, tracks are easy to load.
