The DeLorme Earthmate PN-60 updates the PN-40 with improved battery life, expanded internal memory, and activities (similar to Garmin’s profiles). Power management is one of the biggest improvements, as short battery life was a common complaint with the PN-40.

- The DeLorme PN-60w is slated to allow wireless communication between units, following a promised firmware update
- The PN-60w can be paired with the SPOT Satellite Communicator to allow you to send messages from the field via satellite
Note: Much of the following is adapted from my hands on review of the DeLorme PN-60w.
DeLorme PN-60 hardware
The form factor of the unit remains unchanged from previous generations, as you can see at the top of this post. 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 data cable connection is proprietary (bad), but it avoids possible waterproofing issues caused by a mini-USB port (good). Inside the battery compartment is a full-size SD card slot.
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. These two features are enabled by placing the device in Power Saving mode.
DeLorme PN-60 interface
The interface remains very similar to previous models, though I believe the main menu has improved graphical elements…
Here are some other sample screens:
Maps and imagery
The PN-60 comes with a set of disks containing TOPO USA 9.0 (vector) maps of the US and Canada. It’s now very easy to pick a region and install it to the device. 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. I covered this in more detail in my PN-40 review. Here are USGS topo and aerial imagery samples (courtesy DeLorme):
Other improvements to the PN-60 series
Other changes since the PN-40 include:
- 3.5 GB of internal memory (vs. 500 MB in the PN-40)
- Activity profiles (Hiking, Cycling, Geocaching, etc.)
- Screen rotation (lets you flip the device upside down; does not work in landscape mode)
DeLorme PN-60 performance
NOTE: The following refers to my field tests of the PN-60w.
I tested the DeLorme PN-60w against either the Garmin GPSMAP 60CSX and 62s on various trips. Most testing was done with the units mounted on the handlebars of my mountain bike, although some testing was also done while hiking. 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. I prefer this type of test because it (mostly) removes issues related to satellite constellation variability, aerial photo registration accuracy, etc. It’s merely testing the device against itself, to see how well the track matched up on the way in and then back out a short time later.
Performance was generally comparable to that of the other units. Sometimes the PN-60w performed better, sometimes one of the Garmin units. I routinely saw track separation errors of 100’ or more when biking, where high downhill speeds often produce greater errors. When hiking, errors maxed out around 40’. I think it would be overkill to post all the tracks here, but to give you an idea what I’m talking about, here is a blown up typical section of a PN-60w track…
In terms of altimeter accuracy, the PN-60w’s Elevation Climbing data field generally recorded total ascent around 10% higher than what was expected based on USGS topo maps.
I did notice occasionally delays of a second or so in response to button presses. It wasn’t often enough to be extremely annoying, but it was certainly enough to notice.
Paperless geocaching with the PN-60
To load caches, you can transfer a single geocache directly from geocaching.com, use DeLorme’s Cache Register widget, or transfer a pocket query via Topo USA. I found the PN-60 series to be as accurate as my Garmin 62s, settling down just as quickly.
Shown below are some geocaching screenshots. Unfortunately you have to scroll down to get to the logs; there is no separate menu item to access them. Perhaps a bigger downside is that there is no ability to filter caches on the basis of difficulty, terrain, size, etc., a feature found in many recent models introduced by Lowrance, Magellan and Garmin.
PN-60 data management
The PN-60 utilizes a file system for data management. This has advantages and disadvantages. You can have waypoint files for specific areas and track files for specific trails, and only load the ones you need.
On the downside, you cannot load a file of waypoints and a pocket query file of geocaches at the same time. So you can’t be navigating to a waypoint and see nearby geocaches on the map. There are ways to combine data sources, and get them all into one .gpx file, but then you’re talking about extra prep time.
And you can only load one track file at a time, so if you have trails for a given area set up as one trail per track file, you cannot see all the trails. Again, with data manipulation in Topo USA, it is possible to overcome this.
Navigating with the PN-60
Navigating to waypoints and geocaches, and following routes, functions pretty much as expected. I’ve been spoiled by Garmin’s advanced track navigation feature though, and was disappointed not to be able to display the distance to waypoints along a track. The image at right shows a track being navigated. You can display the distance to the end of the track, but not to waypoints along it. I am told that there are improvements on the roadmap in this regard, although I’m not sure exactly how those will be implemented.
On the road
One advantage the PN series has is the built-in ability to do highway navigation. Unfortunately, this is compromised by the small screen, difficulty entering an address, and limited database. I would not suggest using this as your primary auto GPS, nor would I depend on it to get me to a job interview in a strange city. However, hikers, geocachers and others may find it useful for getting them to the trailhead locally. It is probably best used in conjunction with POIs, waypoints or geocaches on the device, as opposed to addresses you have to enter. Don’t expect to be given directions to a specific address either; in looking up an address with a street number of 789, I was given a 10 block range (414-1498) as the best choice for a destination.

- Can load aerial imagery, USGS topos and NOAA charts (subscription required)
- Topo USA vector maps easy to load
- 3.5 GB internal memory
- Uses a full size SD card, rather than a micro
- Built-in highway navigation capabilities
DeLorme PN-60 cons
- Small screen
- Battery compartment thumb screws are a pain
- Limited track navigation functionality
- Proprietary cable
- File management system limits you to one file (per type) open at a time
- Weak highway navigation capabilities
- No geocache filtering for difficulty, terrain, etc.
Conclusion and recommendation
Highly recommended for previous DeLorme Earthmate owners looking to upgrade. The PN-60 is a powerful device, with an extensive feature set and capabilities. Nevertheless, I find myself reluctant to recommend it beyond this, partially due to its small screen. I also have concerns recommending it for first-time handheld GPS owners. It isn’t any more complicated than earlier Garmin units, but that company has made some strides with their Dakota/Oregon/62/78 series interfaces. Nevertheless, folks upgrading from a different brand shouldn’t have too much trouble learning the PN-60.
