When it comes to geocaching, you don’t really need a pricey and sophisticated GPS unit. The most important things to consider when it comes to GPS for geocaching are its usability, accessibility, and durability. It is very common for outdoor gear to get seriously abused. GPS can get smashed in bags and packs, rained on, frozen, dropped in an icy river, and so forth. Luckily, most receivers are designed from military specs to withstand a lot of electronic killing factors like moisture, dust, and vibration. The following is a list of things for you to consider when buying your first GPS for geocaching.
- Can you see the information on the screen easily? You screen should be easy to read in bright sunlight and at night. You should also consider a GPS unit with a good contrast and reasonable screen size. Color is a plus because it helps define map features, although it does drain the battery power faster.
- Does your GPS unit lock onto satellite signals quickly and accurately? Your GPS unit should be able to receive guidance through tree covers, the windscreen of your car and while inside your travel pack or pocket. A GPS unit with 12 parallel channels should be able to meet all these qualities. Most GPS manufactured after 1997 will have 12 channels while older ones are much slower and may not be as accurate.
- Can you understand the information you receive easily? You need a GPS that, at minimal, marks cache locations and significant points along the way (waypoints) - like laying a trail of breadcrumbs. Your GPS unit should store at least 500 waypoints.
- Is it comfortable to carry around? Your GPS unit should be compact and lightweight. It is recommended that you look for one with a wrist strap.
- Is it waterproof? Some caches are hidden under or near water so sooner or later your GPS unit will get wet while your out on your geocaching adventure. Plastic bags and boxes can give a little additional protection, but it is better for your GPS to be waterproof to begin with.
- How long will the battery last? A long battery life is a must especially for those hard-to-find, remote caches. You don't want your battery dying on you in the middle of nowhere.
- How large is the GPS memory? The memory is used to load detailed topographic or street-level digital maps into the receiver. Topographic maps use a lot of memory so it is recommended that your GPS has at least 8 mb of memory. If possible, look for a GPS unit that includes the ability to accept a memory card so you can have as much memory as you need.
- What other power sources can you use? You should use a cigarette lighter power cable whenever possible to save batteries. Also, look for one with a solar charger for use when looking for hard-to-find geocaches. If you are only using batteries, make sure that you bring spares.
Here are other advanced features for you to consider when buying your first GPS unit. These features will make it easier for you to locate all those geocaches.
- Built-in Compass. It really comes in handy when you get within 100 feet of the cache you're looking for.
- Altimeter. This shows your elevation. They are convenient when looking for vertically hidden geocaches.
- External Antenna. This will help you keep your satellite signal while under heavy tree cover or difficult terrains.
- WAAS-Enabled. This basically means that your GPS unit will be accurate within 3 meters (10 feet) 95% of the time.
