The basic intention of a GPS tracking system is to allow the user to fix his or her location at any time. That is achieved by reading the screen on a hand-held unit that picks up a signal from a series of satellites in geosynchronous orbit around the Earth.
There are in fact various different styles of Global Positioning System units. One style is optimized for use at sea on a vessel, others function better in vehicles, and still others are ideal for use when hiking. Some fundamentals apply to each style, however.
The user must have to be capable of operating the controls and interpreting the display without being knowledgeable in electrical engineering. Many are not much more than electronic maps, various models will simply be static (they only store pre-loaded charts); others are capable of downloading fresh charts via wireless or through a Laptop / Internet connection. Some will certainly offer cryptic longitude and latitude readings, calling for you to interpret the location by using a map.
Garman GPS is the market leader of these tracking systems, but they are not the only maker. Lowrance, Magellan and various other manufacturers make great models, as well. With such an assortment of models and manufacturers to select from, what should you be looking for? Of course, the answer will depend on what you aspire to use the tracking unit for.
For a backpacking GPS device, long battery life is essential. Ploting a route through some wilderness areas is typically done in a reasonably casual way, unless you become lost. If that happens, you require the device to remain active for a long time.
A water-proof tracking unit is a near must, as swift, unforeseen changes in weather conditions are typical in camping regions. Rain can start and finish before you know it. You do not want your GPS unit to stop operating or become damaged when you’re finding the way back to the campsite. Always remember to inquire if the tracking device you’re debating is robust. It is not ideal if it can not hold up to the harshness of the outdoors.
The amount of maps and routes, as well as the quantity of coordinates or waypoints, which a system can hold differs by model. The higher the memory the model has (similar to your laptop), the more it can store.
Map capacity bought to be at least twenty, but fifty or more is desirable. Coordinate capacity is often a strong five hundred for many units, but given that each position is a coordinate, this can add up quickly. Here again, more is preferred, but you pay up for that.
The facility to align the maps you see in various compass directions is very useful. The directions (bearing) to your next coordinate is standard, but verify to be certain. Knowing where you’re at a given time is frequently almost worthless. Your objective is to move from one point to the next, not merely to identify which latitude and longitude you occupy.
Ergonomic elements are reasonably important. The ploting device bought to fit snugly in your hand and not be too large as to result in fatigue. It needs to be pocket-size, but light enough so not to cause irritation when it’s there.
Be geared up to pay a little extra to acquire the ideal GPS tracking system. It bought to last for several years as they’re already packed with features, so you should not need to replace it within a year with the latest unit.
