Features and Capabilities that Make a Portable GPS Superlative
- Waterproof and durable to withstand the elements, and rugged use. Small and lightweight so you can carry it easily in a pocket, pack, or clipped to clothing, and can be operated with just one hand.
- 12 channels to lock on to the satellites; older models with less are too slow and not accurate enough.
- WAAS (Wide Area Augmentation System) enabled – this means your GPS unit will give you up to five times the accuracy because you're linked in with a system of satellites that ensures position accuracy within 10 feet (3 meters) for about 95% of your searching endeavors. Many Garmin models have this technology.
- Plenty of waypoint storage capacity. Waypoints mark where a geocache is. You can also input them as you go, to easily retrace your steps back. Expandable memory means detailed routes and points of interest for all your far flung travels in the backcountry are right at your finger tips.
- Removable SD Card for any additional maps you want on it.
- You want to be able to read the screen easily in direct sun, under heavy clouds, with your shades on, and at night.
- Long battery life. Easily replaceable and/or rechargeable.
- Preferably a USB cord compatibility to hook into your computer for downloading data such as maps and cache coordinates from software or online.
- A built-in compass that works when you’re not moving.
- Altimeter to know your elevation and to further assist you in acclimating to your surroundings.
- Mapping capabilities with terrain features included which either come with the unit, or the unit has the capability and storage room to download them off the Web or from software.
- A powerful external antenna certainly comes in handy when you're under a thick patch of cedars or deep in the canyons walled by either steep rock faces or skyscrapers. It keeps you from losing your lock on those eyes in the distant sky, the GPS satellite systems.
- A rocker key pad (operates with a wheel similar to an IPod) or touch-screen.
