How to Buy a Waterproof GPS

A Global Positioning System (GPS) is a useful tool for navigation for many different applications. GPSs are commonly used by drivers to provide directions and navigation between destinations. A waterproof GPS is especially helpful to hikers, campers, and other backcountry travellers as they do not rely on cellular service in order to function. Instead they work by relying on satellite information which is available everywhere on the globe.

A waterproof GPS is often used in inclement weather such as rain or snow and is also made to handle submersion, which makes them incredibly durable, a necessity for outdoor enthusiasts who require more rugged equipment. GPSs come with a variety of features that are suited to different applications, so shoppers should clearly articulate their needs to determine which GPS is best for their intended purposes.

How a GPS Works

A GPS is an electronic device that works by balancing time against the position of the satellite. By constantly sending messages back and forth between the GPS and recording the time, the GPS is able to exactly pinpoint the location of the unit as well its proximity to other identifiable landmarks or destinations. More advanced GPSs also report things like weather, traffic, and altitude based on additional satellite information. Some GPSs also provide navigation to drivers, cyclists, as well as backcountry travellers.

Since GPSs have grown rapidly in popularity. The infrastructure required to use them is quite extensive. In order for a GPS to be accurate, four satellites must be "visible" or providing feedback to the device. This allows the GPS to determine the points of intersection of the four satellites which provides the location of the unit. Once that information is determined, additional information is eventually derived. Some more advanced units determine their position with less than four satellites being visible. These are an excellent choice for users who may be in more remote locations with heavy, overhead cover.

Users of a GPS

Without a doubt, the most common use for a GPS is turn-by-turn navigation in a vehicle. Waterproof GPSs have a particular appeal to those who intend to use them outdoors. This might include hikers, cyclists, and motorcycle enthusiasts who are likely to expose the unit to the outdoors. While GPSs fall into two main categories, military and civilian, civilian applications are the only ones relevant to typical consumers. The chart below outlines some of the typical applications for a GPS unit and whether purchasing a waterproof unit is practicable.

Application

Waterproof

Astronomy

Depends on location

Fleet Tagging

No

Geofencing

Yes

Navigation

Depends on mode of transportation

There are many more applications which include aviation, robotics, geotagging, geocaching, and cartography. Since GPSs also have military applications, the federal government regulates the models that are sold to civilians so the technology available to the average consumer is not nearly as advanced as it is in the military. While this may be disappointing to some, the technology available to civilians is more than adequate for any non-military purpose.

Astronomy

GPSs provide users with the exact time and location. This is incredibly useful in terms of astronomy. It allows them to know where to look to find the planets, stars, comets, meteors, or other astronomical object that they are seeking. Often times, GPS units are connected to a telescope, or other viewing device, and used simultaneously to get a precise location. Some more advanced models even provide information about the object being viewed. This is especially useful to beginner astronomers who do not have a more senior person to teach them.

Cartography

Cartography is an obvious use for any GPS unit. Cartographers make maps and GPS units provide precise location details to customers. They also help record topography, trails, and other landmarks that are later used by the cartographer to create the map. GPS help to create accurate maps that may include additional features that traditional cartography techniques are not well suited to. They assist with aerial maps, water maps, and other types of maps that are were previously very difficult to create.

Fleet Tagging

Fleet tagging is a relatively new prospect that allows each vehicle in a fleet to be tracked from one central location. Bicycle courier services, delivery drivers, service trucks, and other vehicles are all able to be viewed from a central location if they are equipped with proper GPS technology. This is extremely useful for businesses who need to track the location and estimate travel times of their service providers. This also allows employers to remotely supervise their employees ensuring that they remain on task and deliver timely service.

Geofencing

Geofencing is a useful tool for both parents and employers. Geofencing allows the user to program a GPS to notify that person when the GPS leaves a certain area. Parents may program the GPS to alert them when their child is outside the permitted zone. Employers may program the GPS to do the same when an employee leaves a designated area. This is a great way to monitor and restrict the area where an individual is located without being overly invasive, as the user is only alerted when the GPS unit leaves a certain area.

Navigation

The most common and familiar use for a GPS unit is simple navigation task. GPS units are used for navigation in a variety of different settings which include aviation altimeters, aquatic, pedestrian, backcountry compasses, and automobile. Whether the GPS should be waterproof depends on how much exposure to inclement weather, and water, the unit may receive. Obviously, the more water the user is exposed to, the greater the need for a waterproof device.

Other Helpful Uses

GPS units are not only useful for moving towards a destination, they also help to record progress using waypoints, therefore users have the ability to easily backtrack their steps. This is great tool for users who are heading into uncharted territory and want to be sure they have a route back out. It also tracks rates of speed, distance, and some advanced models include weather, traffic, and other similar information. Finally, some GPS units include messaging capabilities much like a walkie talkies, but more reliable since they use satellites instead of radio signals.

How to Buy a Waterproof GPS on eBay

Buying a waterproof GPS is simple and straightforward when shoppers rely on eBay for their shopping needs. eBay makes it easy for shoppers to find the best possible deals on electronics best suited to their needs with a variety of different search tools and filters. The best place to begin is with a basic keyword search which is done by entering simple terms into the search bar found on every page of eBay's website.

Once these results are displayed, shoppers have the option to sort, organise and filter those results in different ways to assist in finding the ideal product.

Conclusion

A waterproof GPS unit is a useful tool for many different kinds of travellers, but particularly those who are exposed to large quantities of water, such as boating enthusiasts, or inclement weather such as cyclists and hikers. Waterproof GPS units are used in many different applications, and have a variety of features so it is important for shoppers to narrowly identify what their intended use for the product is. This ensures they not only get the features they need but also avoid undue expenses paying for features that are not suited to their purposes. Whether a user is a cyclist, boating enthusiast, pilot, hiker, or business owner, a GPS may have great appeal and finding the right one is easy when they use eBay for all their shopping needs.
