The Garmin company produces navigators for different purposes and users. Car navigators keep drivers on track, and marine instruments combine the functions of a navigator and an echo sounder. For athletes, a special sports navigator "Garmin" is produced, which makes training more effective. Devices for outdoor activities have become reliable assistants for tourists and hunters. Also a great advantage is the ability to update the GPS navigator in a timely manner.
How to determine what is important in the Garmin navigator
If the Garmin navigator is supposed to be used at sporting events, then maps may not be needed. For a device that will be used for hunting or fishing, additional map support is required. A standard set of maps is included with the navigator free of charge.
A device intended for use in a car must have a large screen. The mass of the device does not matter. If the navigator is intended for pedestrians, the lighter the weight of the device, the better.
Large memory size allows you to store tracks, routes and maps. The operating time without recharging is an important criterion when choosing a navigator. Additional functions of the device, such as a magnetic compass, altimeter or barometer, are quite specific and are needed only for a certain part of users.
Necessary accessories for Garmin navigators
Important accessories for your navigator are a USB cable for a personal computer (usually included) and a car charger to save batteries. The navigator can operate on conventional AA batteries and AA rechargeable batteries.
For a car navigator, you will need to purchase an external antenna. Covers allow you to protect the device from damage, but make it somewhat difficult to work with the navigator. A special bracket is required to mount the device in a car, bicycle or motorcycle.
Not all modifications have a memory card included, so you need to buy it additionally. The removable memory card in the device is ideal for experienced travelers and backpackers.
Cartography for Garmin navigators
Maps for navigation devices are the most important attribute. It is with the help of the map that the user will be able to orientate himself in space and achieve his goal.
Maps are referenced to the longitude and latitude of the Earth and contain various types of objects. The types and number of objects depends on the type of map. For example, the object could be a forest, river, city, road, or landmarks. Most of the maps provide maximum detail. Many navigator models are supplied with a standard set of maps on sale.
The manufacturer is developing maps based on satellite imagery specifically for Garmin navigators. To survey water depths or mountainous areas, the magnetic resonance method is used, which makes it possible to create maps with a three-dimensional image.
Maps for Garmin navigators are divided into road and tourist maps. Road vector maps are linked to highways and junctions. Tourist maps contain maximum information about recreation sites, attractions and green areas. A good full-fledged map will allow you to plan your travel route in advance, marking the necessary points in the navigator.
The range of maps for navigators is frequently updated in accordance with user requests. Also, navigator users can make unique maps for their routes on their own. The owner of the Garmin navigator can add the necessary objects and labels to existing maps or create a new one. Special software products have been developed to correct and create custom maps.
