Gadgets play a role in practically every part of our lives, and with the proliferation of smart phones, laptops, MP3 players and other electronics, it’s getting harder for people to disconnect from technology. When my family and I leave the pavement behind, we have a rule that anything with a plug or batteries stays behind, with one important exception.
Electronic navigation plays an important role in our outdoor getaways. From helping to find that perfect lakeside campsite or backcountry trailhead to guiding us safely back to camp after a long day of trekking, today’s sophisticated and user-friendly GPS units are indispensable.
We’ve beaten the bushes, as it were, to bring you these examples of the latest and greatest offerings in automotive and hand-held GPS navigation systems that can help to enhance your camping experience.
For 2011, outdoor-optics leader Bushnell introduced two new models of its key fob-sized BackTrack GPS, BackTrack Point 3 ($70) and BackTrack Point 5 ($90). Both are simplicity defined — just press a button to set a location you wish to return to, whether it’s camp, trailhead or car. Both new models feature improved graphics and have the latest in GPS technology for quick satellite acquisition and signal sensitivity. The BackTrack Point 3 comes with a key ring attachment, while the BackTrack Point 5 includes a carabiner clip, allowing for easy attachment to backpacks, belt loops or zipper pulls. With the BackTrack weighing only about 2 ounces, campers and hikers likely won’t know it’s there.
The BackTrack Point 3 allows users to mark up to three separate locations or waypoints and it guides them with an electronic compass-arrow. The BackTrack Point 5 stores up to five separate locations and features an integrated digital compass and latitude/longitude coordinates. It also displays time of day, temperature and altitude.
Both offer distance-to-go with an arrow. A backlit screen is provided for low-light conditions. To extend operating hours from the two AAA batteries, an Auto Off feature powers down the unit five minutes after the last button is pushed. Bushnell: 800/423-3537; bushnell.com.
Delorme’s new Earthmate PN-60w is the first hand-held GPS specifically designed for combination with a SPOT satellite communicator. It can provide outdoor enthusiasts with a safety net and reliable communication with the world back home.

Using Earthmate’s internal keyboard, freeform text messages can be sent to individuals or groups. The SPOT unit also has stand-alone capability to send location-based SOS notification signals to emergency responders anywhere in the world.
The PN-60w ($550 with Spot) is no slouch as a stand-alone hand-held navigator, providing a 32-channel GPS receiver, fast dual-core processor, three-axis electronic compass and sensitive barometric altimeter. A large library of available mapping and data includes high-resolution color aerial imagery, USGS 7.5-minute Quad Maps, USGS high-resolution city maps and 150,000 Canada topographic map sheets. For an annual subscription fee of $29.95, navigators can download all the updated land or marine charts and imagery they desire. Delorme: 800/561-5105; delorme.com.
Renowned optics manufacturer Celestron has ventured into GPS navigation with two simple yet sophisticated devices, the reTrace Lite ($60) and the reTrace Deluxe ($100). The reTrace units are relatively inexpensive but worthy of note because Celetron kept the features pared down while making sure the units had the essentials. Small enough to carry in your pocket and easy to use, they are perfect for tasks ranging from locating your car in the parking lot of a crowded stadium to getting back to that favorite fishing spot.
The Lite is a WAAS-enabled GPS unit that measures up to IPX6 water-resistance standards, and offers a 2-inch, icon-style screen that displays satellite signal, battery status, distance to location, latitude and longitude, and a digital compass. It has the capability to store five waypoints. The Deluxe (pictured) gets a 1.8-inch color TFT screen, an altimeter, pressure and trend barometer, a thermometer and a real time display. In addition, it has the ability to upload 50,000 trail data logs though a mini USB cable, create map routes and store up to 20 waypoints. Celestron: 310/328-9560; celestron.com.
Garmin has introduced innovations for both the car and hand-held GPS markets. Drivers will appreciate the new Garmin nuvi 2400 Series auto navigators, with five-inch displays and a new range of optional features including voice-activated navigation, real-time traffic alerts and enhanced route calculation.
The 2400 Series has four models: the 2450, 2450LM, 2460LT and 2460LMT. The 2460LT and 2460LMT let operators “wake” their nuvi with a customizable voice command, and then begin speaking menu options to control the unit.

Many of today’s GPS receivers have up to 40 channels or more. What’s the point, given that these channels outnumber the satellites the receiver could realistically track at one time? Your GPS might be tracking six to 10 satellites, but other channels can be used to search for new satellites that might be coming into view. This can improve performance and maintain consistent position fixes if ground obstructions or natural features block satellite signals.
The IPX-7 waterproof rating means an instrument can withstand one-meter submersion for 30 minutes. Most hand-held GPS units that don’t meet this standard are generally referred to as IPX-6, able to withstand heavy rain and splashing.
Transflective LCD displays use ambient light to provide illumination for the display, making them shine in direct sunlight. TFT LCD displays are a variant on liquid crystal displays that use Thin-Film Transistor technology to improve image quality and contrast. Screen resolution is measured in pixels (for example, 320 x 240), with the higher the number indicating a sharper picture.
The Wide Area Augmentation System was developed by the Federal Aviation Administration to improve GPS accuracy. Using a network of ground-based reference stations to measure variations in GPS signals, these deviations are sent to geostationary WAAS satellites, which then broadcast the appropriate correction signals back to Earth. WAAS-enabled receivers use these corrections to improve accuracy, usually to within a distance of three to five meters.
A lock on three GPS satellites is required for a GPS unit to determine your position in 2D (two positions), latitude and longitude. Some units can use the signals from four satellites to fix and provide a 3D position, latitude, longitude and altitude.
Hand-held GPS units can provide altitude information based on GPS location and topographic map data or barometric pressure measured by an internal sensor. Pressure-based readings are generally more accurate and have the added benefit of providing barometric pressure trends to indicate changing weather patterns.
