Hand Held GPS
Hand Held GPS – When selecting a hand held gps device for hiking, you should consider a unit that provides good navigation capabilities and will not encounter satellite reception problems.
For navigation purposes, a basic hand held GPS device should be lightweight with a sturdy waterproof design. You should consider a larger high resolution color display screen for easier daytime viewing. Depending on your budget, you can find units that include features such as touch screen interface, barometric altimeter, tri-axial electronic compass and 3D aerial imagery. Another important feature is that the hand held GPS device can be set up properly for navigation. Not all hand held GPS devices can accommodate topographical maps and most GPS units do not preload these detailed maps. Fortunately, there are plenty of free (and legal) topological maps out there that you can download.
Regarding reception capabilities, you should consider hand held GPS devices equipped with the multi-parallel channels feature that enables multiple GPS satellites to simultaneously track your location, resulting in faster and more reliable functioning. With high-sensitivity receivers, such as those with the SiRFstar III or MediaTek chipsets, you can keep the device in your pocket and still have good reception on demand. Keep in mind, some of this is dependent upon how the satellites are positioned at that time of day.
If you venture far off the beaten track, or go it alone, some hand held GPS devices have integrated a feature that allows you to communicate with the outside world and allows you to send a “help” message, even where there is no cell signal.
Determine your budget, review product comparison charts and customer reviews to determine which of the features are most important to you and fall within your budget considerations for your hand held GPS.
