I prefer this type of test because it (mostly) removes issues related to satellite constellation variability, aerial photo registration accuracy, etc. All tests consisted primarily of out and back segments each track from the devices was examined for track separation errors – how far each track varied on the way out compared to on the way back. Most testing was done with the units mounted on the handlebars of my mountain bike, although some testing was also done while hiking. I tested the DeLorme PN-60w against either the Garmin GPSMAP 60CSX and 62s on various trips. NOTE: The following refers to my field tests of the PN-60w. Screen rotation (lets you flip the device upside down does not work in landscape mode).Activity profiles (Hiking, Cycling, Geocaching, etc.).
Here are USGS topo and aerial imagery samples (courtesy DeLorme):
I covered this in more detail in my PN-40 review. To download raster imagery such as aerial photos and USGS topos to the device ( $29.95 annual subscription required), you still have to process them through the TOPO USA software. It’s now very easy to pick a region and install it to the device. The PN-60 comes with a set of disks containing TOPO USA 9.0 ( vector) maps of the US and Canada. The interface remains very similar to previous models, though I believe the main menu has improved graphical elements… These two features are enabled by placing the device in Power Saving mode. The improved battery life results from power management changes such as use of an ambient light sensor to control the screen backlight, and letting the accelerometer sense when the device is not in motion, allowing GPS tracking to be temporarily minimized or disabled.
Inside the battery compartment is a full-size SD card slot. The data cable connection is proprietary (bad), but it avoids possible waterproofing issues caused by a mini-USB port (good). I’m not a fan of the battery compartment thumb screws found on the rear, but fortunately, improved battery life means you don’t have to mess with them so often. The form factor of the unit remains unchanged from previous generations, as you can see at the top of this post. Note: Much of the following is adapted from my hands on review of the DeLorme PN-60w. The PN-60w can be paired with the SPOT Satellite Communicator to allow you to send messages from the field via satellite.The DeLorme PN-60w is slated to allow wireless communication between units, following a promised firmware update.How much does it cost?
