Waterproof GPS Handhelds - Practical Features For Modern Sportsmen
GPS were originally used in military and other government applications. Today, it is also used in other areas like navigation and sports. Though GPS is composed of electronic devices, some handhelds can be used in water.
Sportsmen that are focused in water activities like kayaking and canoeing can benefit from this. They can now enjoy the basic features of waterproof GPS handhelds, calculate distance between points, and have a map display according to latitude and longitude coordinates.
Some features should be understood before buying waterproof GPS handhelds, as they can be found in its specifications, and worth the comparison among models. Such features are also suitable for older and non-waterproof units.
In buying waterproof GPS handhelds, some characteristics should be understood because they often appear in specifications sheet and are good measures when comparing units. The following terms are also applicable for non-waterproof GPS.
Augmentation System: This system serves as the corrector for the received signal by the GPS. It can be found in the specifications as WAAS, or Wide Area Augmentation System. It increases the accuracy of the signal for positions outside 10-feet from the unit. WAAS-enabled units are five times more accurate than WAAS-disabled units.
Topographical Maps: Most GPS can electronically display 2D or 3D maps, but older models do not. For such models, plotters will be required to have a printout of the map. Advanced models can go beyond normal topographic information by implementing Digital Elevation Model technology, commonly called as DEM. It is a feature to have better visualization of contours at different zoom levels. Moreover, handhelds can store new maps by accessing data cards and compact discs.
Wide Area Augmentation System: Commonly known as WAAS, augmentation system corrects the signal received by the GPS for distances beyond 10 feet. Enabling WAAS can increase accuracy up to five times.
Advanced features of waterproof GPS handhelds include touch screen display, switch controls for various activities, expansion slots, and digital compasses. High-end units have the feature to display water depth, harbors, and other marine information. Some also comes in floatable packages for easy retrieval when dropped in water. In addition, some unit incorporates GPS with two-way radios, enabling sportsmen to have a 5-mile range communication. However, such units should first acquire FCC license before using to ensure that it will not interfere with other electronic device. - 2368
