Handheld GPS Buying Guide

Functionality

Where and how you’ll be using your Handheld GPS device will determine which one is best for you. As the name implies, Handheld GPS units are lightweight and designed to fit comfortably in your hand. Many of these pocket-sized units also come equipped with a belt clip which can come in handy for long hikes or adventures that require two free hands. Even wrist-mounted models are now available, like the Garmin Forerunner 305, and are favored by hikers and bikers who need to check position at a glance. Although Handheld GPS device screen sizes are smaller than most built-in vehicle models (2 inches versus 3-5 inches), they can still be used while driving. If you’ll be using your Handheld GPS in and out of the car, look for models with optional dashboard mounts for maximum flexibility.

Now that you know where you’ll be using your Handheld GPS Device, how will you be using it? GPS devices are available with and without mapping. Handheld GPS Devices without mapping like Garmin’s eTrex are less expensive and easier to learn how to use than those with mapping. However, you will need to be able to read and plot map coordinates (this will satisfy the needs of most hikers, bikers and geocaching enthusiasts who simply want to track their point of origin, view a log of their journey in progress and find interesting points along the way). If you’re buying exclusively for outdoor use, consider models that have altimeters and/or compasses. Some wrist-mount models even include heart-rate monitoring. GPS devices that feature mapping differ from non-mapping devices only in that they include a Basemap.

Maps and Data Storage

Almost all mapping GPS devices come with manufacturer-installed US street maps. Additional software is available if you need off road or international mapping capabilities. Look for device software that offers turn-by-turn directions and/or enables you to upload your own maps, Waypoints and Points of Interest (POI) . If you’re buying add-on software for your GPS Device, be sure it’s compatible with your computer. Mac users are limited by the availability of compatible software and should do further research before purchasing any GPS device. Even if you’re a PC user, you want a device with your computer to ensure easy transfer of updated maps and firmware from your computer (via the manufacturer’s Web site or CD-ROM) to your device.

How much storage you choose depends on how frequently and extensively you travel and whether you prefer to upload your data with or without the aid of your computer. If you need to save map information for several areas, you’ll need space to store them (a single Metropolitan area takes approximately 8Mb of storage space). If you prefer not to upload your data to your computer, additional memory can be purchased in the form of Compact Flash (CF) or Secure Digital (SD) cards which can be swapped on the road or in the field as needed. If you prefer to store your data on CF or SD cards, you’ll need a GPS Device with the appropriate slot for data access.

Interface

Handheld GPS Device screens are typically 2.1 inches (wrist mounts are even smaller). Often, these smaller screens aren’t in color (Handheld GPS devices with color screens will cost you more, but if color is easier to see, it’s worth the investment). Above all, you want your device’s display to be easy to read and offer easy-to-navigate menus. Your most frequently used functions should be no more than two (2) screen taps away and it should be no more than another two (2) screen taps to get back to the original screen. Button size and placement are also considerations—if you’re device is awkward to use, you’re less likely to take advantage of all its features and functions.

Power Source

Handheld GPS devices are designed to spend more time out of the car than in. Battery life in relation to usage is a key consideration. Purchase additional battery packs if you think you’ll need them and at least one additional pack even if you don’t. Cigarette lighter adapters give you another charging option for in-vehicle use alone or on your way to and from your outdoor activities. If you’ll be outdoors for an extended period of time, solar chargers, like the iSun are also good options.

Accessories and Options

Handheld GPS device are more prone to falls than other GPS devices. Rubberized cases minimize impact and can protect your device from damage after a fall. Likewise, if you’ll be using your device near water, look for models that are waterproof, not just weatherproof. Waterproof means the device can be submerged in water without sustaining damage, however, not all waterproofing is created equal: be sure to check the ratings (for example, an IPX7 rating means the device can be submerged in up to three (3) feet of water for 30 minutes).
